ImageField woes
I want to expand on the ImageField functionality of django. Mainly, I
want to check the dimensions of the image the user is uploading, and
resize / crop where appropriate. I would also like to set compression
amount, and perhaps even allow for watermarking. I know there are
several libraries out there that do this, but I want to keep it as
lightweight as possible, and haven't had much luck with sorl.
It seems to me the best way to do this would be to create a custom
field type, so I could do something like this in my model:
image_tb = models.CustomImageField("Thumbnail Image", upload_to
='uploads/projects', size=(50, 50), compression="60", watermark="path/
to/watermark.png")
Is this the best way to do something like this? I understand that you
could also hijack the save method, but I might want to have more than
one image field in each model meaning the sizes might vary. Can anyone
point me towards any articles which will help me on my way?

What data structure to use, and how?
Hi all.
I think django really rocks, but i have a question:
I wrote a script in python that will get some values from servers and
puts in them in a dictionary.
The data is in the following format
{'somehost': ['yes', '2'], 'remotehost': ['yes', '1'], 'localhost':
['yes', '1']}
In python, i can then print the values as such:
>>> print "Server: "+server+" Version: "+serverlist[server][1]+"
>>> Reachable: "+serverlist[server][0]
Server: somehost Version: 1 Reachable: no
Server: remotehost Version: 2 Reachable: yes
Server: localhost Version: 1 Reachable: yes
In a django template however, this doesn't go far.
The serverlist[server][0] type notation gives an error when used in a
django template, so i tried this instead:
{% block status_table %}
{% for server in output_list %}
{{ server }}
{% for value in server %}
{{ value }}
{% endfor %}
{% endfor %}
{% endblock %}
This prints each letter of the server name in different cell, which is
not what i want.
How can i retrieve the 'version' and 'reachable' values in the django
template?
Many thanks in advance.
Jon

Re: user object in login.html
Simply have an 'if logged in:' clause at the beginning of your login view definition that redirects to the /loggedin/ view if it matches. Of course this implies that you know some variable that will always match once someone is logged in. Most likely, django sets this already. If you cannot find one, you just set one yourself. I am new to django, only started learning it last week, so the solution may look a bit dirty in the eyes of seasoned django developers, but i am sure it will work. Have a look at the forms chapter, and read about the HttpResponseRedirect to see how to go about doing the redirect. HTH Jon.

Re: user object in login.html
Ah, and if you only want to display a message on the login page,
that's possible too. In that case you don't use the redirect in the
view, but use an if clause in your index.html template.
Something like this:
{% if logged_in %}
You are logged in already.
{% endif %}

Finding a form field's widget type from the template
I'm trying to figure out how to determine a model form field's widget type from the template. I would like to loop through the fields as opposed to writing out each field explicitly in the template, but in order to loop through them, I need to know the widget type so I can do something special with certain types of form fields (checkboxes, for example).

Re: Considering Django: How simple is customising django-admin?
1. Inlines
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#inlinemodeladmin-objects
2. Form media http://docs.djangoproject.com/en/dev/topics/forms/media/
3. Your example does not require custom template overrides for the
admin HTML, it is possible to simply include a function from your
Model in 'list_display'.
http://docs.djangoproject.com/en/dev/intro/tutorial02/#customize-the-admin-change-list
... In your example the function must return the HTML for the
thumbnail image, and it must escape it and allow tags so that the HTML
shows correctly in the admin. Example (from django-imagekit):
>def admin_thumbnail_view(self):
>if not self._imgfield:
>return None
>prop = getattr(self, self._ik.admin_thumbnail_spec, None)
>if prop is None:
>return 'An "%s" image spec has not been defined.' % \
> self._ik.admin_thumbnail_spec
>else:
>if hasattr(self, 'get_absolute_url'):
>return u'' % \
>(escape(self.get_absolute_url()), escape(prop.url))
>else:
>return u'' % \
>(escape(self._imgfield.url), escape(prop.url))
>admin_thumbnail_view.short_description = _('Thumbnail')
>admin_thumbnail_view.allow_tags = True
You would then include 'admin_thumbnail_view' in 'list_display' in
your Model's admin.
4. As for the thumbnail question, you can look at 'sorl-thumbnail' or
'django-imagekit'. I use my own amalgamation of both, for their
different features.
As for the rest of the question, you can add onto the admin app all
you want with your own views, templates, etc. by hijacking the URL
routing in urls.py to look for '/admin/my-report-page' and route that
to your own app. To integrate this into the admin you can simply edit
the template for the main index, or use 'django-admin-tools' which
gives you a much nicer way of adding onto the admin with your own
dashboard links and modules. Or you may watch out for 'django-
grappelli' to soon integrate 'django-admin-tools' into its already
existing body of work, like their Navigation sidebar which lets you
add your own links to the admin index, and Bookmarks which appear at
the top of every admin page. (The latest work is still not quite
usable but still very impressive)
5. I've pondered on both examples myself, but haven't really gone
anywhere with those ideas, so I can't tell you for sure whether it's
possible or not. But my bet's on it being possible, because in the
first example you're simply filtering out child categories based on
the parent category selection, so this would be doable completely with
JS it seems. The second example seems doable as well, though I
haven't tried it myself.

Inherited models...
I wanted to share some fields and functionality in several tables without having to recode all of the field definitions in each table. Obviously, this is an inheritance problem. So I did what I figured was the logical thing: class MyModel (models.Model): date_created = models.DateTimeField(auto_now_add=True,blank=True) date_updated = models.DateTimeField(auto_now=True,blank=True) class Poll(MyModel): class Choice(MyModel): I ran manage.py syncdb and THREE tables were created: mysite_choice, mysite_poll and mysite_mymodel. It appears (although I haven't yet fully tested it) that as expected, the fields from MyModel are implicitly included in the other two tables (precisely what I wanted to happen!) I haven't explored all options, but it appears the two poll tables work correctly and have the extra fields in the database just as I wanted. The question then is can you SUPPRESS the creation of the "abstract class" table MyModel with some flag or option that I don't know about? My review of the django book revealed nothing but I am new to this and may have overlooked something. Having the table isn't an awful thing, I can drop it if I want or certainly just ignore it. However, it really shouldn't be created at all and the ideal thing would be to be able to declare an option for an abstract model class that would suppress the creation of any table for that class.

Strange tutorial behavior...
I successfully ran the complete tutorial (using version 0.96.1) on my
home machine over last weekend without incident.
This week, I tried to bring up my new application at work and started
getting some strange errors in the admin tool. So I went back and
redid the tutorial (to see if I was doing anything different in my own
app that I could understand) and I got the same weird errors (which is
diffferent from what I got when I did this on my home machine - both
are Windows XP, one is Home, one is Office, and the home machine is on
Python 2.4 whereas the office machine is on Python 2.5 - those are the
only differences).
When I try to open the Polls table in the admin tool (which has the
Date/Time), I get the following traceback:

The admin app still appears to work and I can put new entries into the
table. I just keep getting these tracebacks anytime there is a date/
time in the view. This does not appear on the Choices screen which
has no date in the tutorial, but if I add a date/time field, it starts
to happen there. Of course, the traceback indicates that it is
happening on the time.asctime() call.
Is there something that changed in Python 2.5 that causes this?

I simply cut and paste from the tutorial, but here 'tis:

===
from django.db import models
# Create your models here.
from django.db import models
class Poll(models.Model):
question = models.CharField(maxlength=200)

And that is it :-) Like I said, it was cut-and-paste from the
standard tutorial so unless I screwed something up, I don't see why I
am getting the weird error.

Re: Strange tutorial behavior...
Both cases I am using MySQL 5.0. However, new info: this ONLY appears in IE. When I use Firefox, this doesn't happen. I think this may be an IE 6.0 problem. I am using IE 6.0 on this machine, but at home, i was using IE 7.0. Still, this seems really weird. Also, when I switch from http://localhost:8000/admin/ to http://127.0.0.1:8000/admin/, the second exception that was occurring above disappears (only the first remains). And when I switch to Firefox, no problems at all. Any ideas?

Re: Strange tutorial behavior...
Answering my own question here :-) It looks like this is related to the proxy server settings in IE. Home machine didn't use a proxy server - no problem on IE7 (and probably not a problem on IE6 either). On work machine, there is a proxy server in the settings and localhost isn't automatically exempted so this was going through the proxy server. When I added localhost to the sites that don't use the proxy server, it worked in IE6 (and IE7). Firefox apparently always exempts localhost (or at least by default) so that was probably why I saw the immediate difference between IE and FF So, problem appears to have been solved!

you've
traced it down to where the SQL executes, have you gone farther to determine if
somehow that SQL query when issued by Django isn't returning any results while
the one you issue in the mysql command does? It'd be pretty bizarre, but maybe
the SQL is returning the same result but somehow it's getting lost before the
.filter() is returning? The alternative seems to be that the same SQL query is
returning different results, which seems equally bizarre. (There is no
configuration option to change what collation is used for the query, which is
all I could think would change the result as you have described -- Django
always
uses the default collation.)Karen

Apologies for the long silence before responding. Although I do not recall if
this was the precisely the issue (it was a long time ago), I did eventually
hunt
down an accepted bug in Mysql that makes the "in" clause unreliable,
particularly when used in subqueries. The recommended workaround was to replace
with joins, however my preferred solution was to use Postgres, which solved
this
problem and worked a treat. I appreciated your responses - so thank you.

Re: Choosing a JS framework to go together with Django
The idea is to generate pure HTML views for non JS clients like search bots. If your view depends on AJAX calls, then it defies the purpose. I've been developing native mobile apps for the past year, so I get your argument about providing REST end points for your data. The point of my original post was to NOT do two different views; one for search bots and one for browsers. I agree that providing a REST interface is the "right" way to provide data for both browsers and mobile apps. To that end, the project I was suppose to work on, used tastypie. // Jon On 14/07/2013, at 15.16, Phang Mulianto wrote: > Hi , > > Why not using REST for serving your data to the Front End app, it can be from > mobile app or just web app with HTML + javascript. > > With that you don't need to worry about redo the template side in django and > in your front end js app. > With REST serving JSON, no template / html needed for the response. > > You can use Tastypie or Django rest framework which still using Django engine > .

Master-Detail Form help needed
I have been struggling mightily with Master-Detail forms in Django. I have done a number of online tutorials but have yet to find a complete tutorial which completely explains models, views, templates, URL patterns related to master-detail forms. I use the Oracle toolsets where creating a master-detail form is just a matter of feeding the template your master table (model) and then selecting your detail table (model). It generates a basic form for you with CRUD controls. Similar to how the Django admin tool works. If someone could point me toward a good comprehensive book chapter or tutorial, I would be much appreciated.

Foreign Key data not showing in formset
I have the following view with an inlineformset for two models:
1. Orders, the master / parent model
2. LineitemInfo, the detail / child model.
FormSet
LineFormSet = inlineformset_factory(Orders, LineitemInfo,
can_delete=True,
exclude = ('ordernotes',))
The edit order_edit view works fine for the master / parent form, but does
not display the child records. I can add records to the child form and they
will save, they do not display however when I select that record (I checked
the database separately).
def order_edit(request, pk):
order = get_object_or_404(Orders, pk=pk)
if request.method == "POST":
form = OrderForm(request.POST, instance=order)
if form.is_valid():
order = form.save(commit=False)
lineitem_formset = LineFormSet(request.POST, instance=order)
if lineitem_formset.is_valid():
order.save()
lineitem_formset.save()
return redirect('order_list')
else:
form = OrderForm(instance=order)
lineitem_formset = LineFormSet(instance=Orders())
return render(request, "orders/order_edit.html", {"form": form,
"lineitem_formset": lineitem_formset, })
I just get the empty fields on the child / detail form where the data
should display. What am I missing? TIA

Re: Foreign Key data not showing in formset
As much as I hate to answer my own questions, I was calling instance of an
empty Order() model rather than the instance of the populated model. So:
lineitem_formset = LineFormSet(instance=Orders())
should have been:
lineitem_formset = LineFormSet(instance=order)

Re: Does Django have a function that can be called by every view function ?
Another +1 for decorators. In fact, the example David S uses authentication and logins as an example of what he wants to do and its already handled as a decorator thus giving him a decent pattern to follow. David S, I'd suggest you look up the @login_required decorator and even look through the Django code to see how it's implemented. Don't be afraid of cruising through the code. As good as the documentation is, the code is also well organized and uses a lot of good pythonic idioms if you're new to the language. Jon.

Re: Where are all the Django jobs?
Django is starting to gain more traction and I do believe we'll start to see a bit more of a hockey stick effect on it's adoption over the coming months. 1.0 being released last year and (at least part-wise) adoption by the Google AppEngine have both been great PR events for Django but I'd also argue that Django doesn't have it's Twitter or BaseCamp yet i.e. a killer application that grabs the mindshare of startup CTO and CEOs that seemingly make them choose Rails. At Thinktiv, while we're a professional services company thats officially platform agnostic, we've chosen Django as our in-house framework of choice for development. Django suits the majority of our customers applications very well (generally interesting presentations and visualization of structured data and media). Whenever we've had customers where we get to influence the framework used, we'll sell Django into the account. However, we've had customers comeback and want to build on Rails for the exact opposite reason from this thread: lack of people in the Austin area who know Python/Django to take on the maintenance work after we've done the initial application build. So it seems like we've got a bit of a chicken/egg problem. Our organization is going continue to evangelize Django in our community. The more that the Django-community sells its virtues in our various consulting gigs the more opportunity we'll get to use the framework we love. To further Malcolm's point above, be a good programmer first. Good programmers should be able to pick up (or already know) multiple platforms, frameworks, languages quickly. Being a first rate programmer who's technology agnostic will open up a huge number of opportunities where you'll get to be the person who influences what gets used in various situations. It's in those situations that you'll get to grab your favorite tool: Django. Jon Loyens Thinktiv, Inc.

Re: legacy site in php
Rather than the structure you suggest, it might be better to think about your exhibition projects not as django projects, but as django apps. Replace pyA and pyB with root/pyA and root/pyB (e.g. make your php directories a peer of the django root...conceptually, of course...you're Python files won't live physically next to your php files, or shouldn't anyway) and control all your django urls through your urls.py file. This would cut down on the duplication you'd probably end up with in the settings.py file, etc... I don't mix PHP with Python, but I do mix PHP with Java in the enterprise and there is, IMHO, no inherent conflict in mixing PHP with anything else. There is some duplication (and will be until you're using a single language), but you can generally keep that to a minimum by using an OO approach on both sides. It does create some internal strife in your mind, though, as you switch between worlds. Use the Force, though, and everything will magically turn out all right. ;) Thanks!

accessing site settings in templates
I can't find a good answer to this in the Django docs: is there a good way to access site-specific settings from your templates without having to put them in context variables? I've got my media served by Apache and everything else by Django. In my templates, I've got an ugly hack to check for the existence of a "site_base_url" variable or default to localhost. This is a mess because I can't test it from my iPod without using a hostname, but I can't get context variables to the views I don't have control over (like login/logout, etc...), so my templates don't have the "site_base_url" for everything. Do I have to write some custom middleware that will add my global application settings to every request, then reference them through the RequestContext I'm passing in to render_to_response? Or is there some other feature of views I'm missing (I've read so much on Django lately, I'm starting to forget what I've read and what I haven't)? Thanks!

OpenID support in contrib.auth
I tried both OpenID integration packages I could find for Django and couldn't get either to integrate in what I felt like was a clean manner (or even get them to work!). I've resolved to simply write my own, stripped-down version of an Auth backend that uses OpenID (additionally storing the auth url in a user profile so I can indicate to the user under what OpenID they're signed in). Before I spend a couple days hacking on this, I was wondering if anyone else has tried (or succeeded) in integrating OpenID with Django trunk? I'm using newforms-admin and the latest egg of python-openid. Since I'm already using user profiles, my goal is to only impact my application by adding an auth handler for OpenID and mixing in the views for openid-begin and -complete. I don't want anything else scabbed on to enable OpenID integration. BTW- The ASL (python-openid's license) *is* compatible with BSD, right? Thanks!

Re: accessing site settings in templates
Sort of, but not really because I wanted something that worked even
using the built-in views (the problem manifested when I started
working with the login views). I didn't have a problem passing my
settings into the templates for the views I created myself, but I
didn't have access to the same arbitrary settings in the templates
created for the built-in views. I had to use middleware to intercept
the context and add the variables, even when using views I didn't write.
It seemed like a fair amount of extra work just to make sure all my
templates had a "media_base_url" variable! :) I've actually changed to
using plain CGI (rather than manage.py runserver) in development so
that I don't have to muck about with proxying the Django server and
other such [*bleep*]...subtleties...to get a coherent environment
where I can test in the GWT hosted mode browser, desktop Firefox, and
the iPod Touch, all at the same time.
Thanks!

Could you let me know what you did to fix this?
My urls.py is very simple, and contains:
-8<---
from django.conf.urls.defaults import *
from django.contrib import admin
from os import path
admin.autodiscover()
urlpatterns = patterns('',
# Uncomment this for admin:
('^admin/(.*)', admin.site.root),
# Index page.
(r'^/?$', 'vmanager.frontend.views.index'),
)
-8<---
My models.py file in my applicaion folder contains the following (I've
snipped aprts of the model definition, as they're not relevant)
-8<---
from django.db import models
from django.contrib import admin
class Person(models.Model):
"""This models a person machine"""
(details omitted here)
-8<---
I've tried alternating between using admin.autodiscover() in my
urls.py, and manually registering my models using
admin.site.register(Person), but I still get the permission error in
the admin site. I've also tried flushing the database, but that
doesn't seem to solve anything. FWIW, my user has is_superuser,
is_staff and is_active all set to true in my database.
The exact message I get in the admin site is "You don't have
permission to edit anything".
Any help would be much appreciated.

There seem to be a few problems. First of all, I'm a little confused about where to use admin.site.register(). A few months ago I checked out the newforms-admin branch to try to get a head start, and I followed the instructions on this wiki page[1], which recommended importing django.contrib.admin at the top of models.py in a given app, then registering the models at the bottom of the same file. Of course, I realise that the documentation is in flux, but at the time, doing that worked. I've now moved that code into admin.py in my app folder. It looks something like this: -8<- from django.contrib import admin from myproj.people.models import Person class PersonAdmin(admin.ModelAdmin): pass admin.site.register(Person, PersonAdmin) -8<- However, when I *also* include admin.autodiscover() in my project-root urls.py, the following exception is raised: ImproperlyConfigured at /admin/ Error while importing URLconf 'myproj.urls': The model Person is already registered If I comment out the contents of my admin.py file, then that exception is not raised, and also if I comment out the call to admin.autodiscover(), the exception is not raised, however I cannot have both active at the same time. A little googling brought up ticket 6776 [2], which seems to have been closed, with the introduction of admin.autodiscover() as the resolution. I'm not entirely sure what is going on there. Regardless, I took Karen's advice, and modified the __init__.py in django.contrib.admin, and added a print statement to see which applications were being loaded. In my case, the output was this: django.contrib.auth django.contrib.contenttypes django.contrib.sessions django.contrib.sites django.contrib.admin myproj.people ... which looks reasonable to me (auth is being loaded before admin, which would suggest that the permissions would be available to the admin app), but I still see the same 'you don't have permission to edit anything' message in the admin application. Any help debugging this would be much appreciated - now that newforms-admin is in trunk, I can't justify continuing development without it, so I'd really like to solve this :-) --Jon [1] http://code.djangoproject.com/wiki/NewformsHOWTO [2] http://code.djangoproject.com/ticket/6776 --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

No, I don't. I should clarify that when I previously had newforms-admin working correctly, it was in a different project. The trouble that I'm having is with a project which I started after the newforms-admin merge. > Alternatively, you are sure you removed the registration calls from your > models.py file?

The admin username and password is 'test'. It's available at: http://jonatkinson.co.uk/static/junk/myproj.zip FWIW, I'm using SVN trunk at revision 7951.

I posted a new template tag for forever-caching resources...
...at djangosnippets: http://www.djangosnippets.org/snippets/991/ I wanted to be able to use the forever-caching capability of Google Web Toolkit with my own resources, so I wrote this template tag to handle any resource. If the file you want cacheable is a JS or CSS file, it will (optionally) use YUI compressor to compress the file first. It creates a copy of your original file called "LONGMD5SUM.cache.(js| css|png|gif|etc...)". You have to set it up separately, but to get the effect of forever-caching, configure your webserver to cache resources conforming to that name. Different webservers do it differently, of course (I use lighttpd), so that's left as an exercise to the reader. In DEBUG mode, the minification and copying is turned off so you don't get a proliferation of files as you develop. I'm not entirely happy with the way I handle relative vs. absolute paths. It's hard to get a scheme that will work in cacheable and non- cacheable mode using the same pathname. I settled on setting DOCUMENT_ROOT in settings.py to my real document root (one step above MEDIA_ROOT) and using "/media/css/my.css" etc... in the "src" and "href" attributes in the template. I have to strip the leading "/" off to make os.path.join work right, but I have to put it *back* after I strip out DOCUMENT_ROOT and send it as a path to the browser. I think there's a better way to handle this and I'd be interested in hearing how to do that. I hope you find this useful. Comments are welcome! Thanks!

SuspiciousOperation exception on ImageField upload

My a cut down version of my model is below: class Promoter(models.Model): name = models.CharField(max_length=100) logo = models.ImageField(upload_to="/images/promoters/%Y/%m/%d/") When I try to upload the logo via the built-in admin interface, I get the following error: SuspiciousOperation at /admin/promoters/promoter/add/ Attempted access to '/images/promoters/2008/08/19/kitten.jpg' denied. In settings.py, my MEDIA_ROOT is set to an accessible directory in my home folder: '/home/username/projectname/media/', and this folder has it's permissions set to 777. I'm currently using the ./manage.py webserver, which (I assume) runs as the same user which starts the process; this is the same user as owns the folder specified above.

Using ETags with Django
Are any of you using ETags with Django? I'm wondering what the easiest solution for determining whether I need to send back a 304 is. I have last-modified timestamps on my models, so I could conceivably query those and match them against the If-Modified-Since header. It seems like I'd be doing two queries, though. Once for the latest timestamp and again for the real objects. The other alternative seems to be to create a model specifically for determining whether result sets have been dirtied or not. I'd have to make sure my update routines updated this object whenever a model got updated that would dirty a result set. Although new content will be added (hopefully) frequently, I'm not sure there will be that much changing once it's been added. I definitely want to reorder the list of content based on weighting a random ordering, so for some views it will be difficult to rely on ETags for caching. Since Django encourages the use of clean urls, though, it seems like I should be able to use ETags with my models, especially when getting the detail for a particular instance. How would I attack this in a reasonably clean (i.e. able to be reused with any views I want ETags for...but not *every* view) way? I'd like hear how others have solved this before I spend a lot of time hitting dead ends. Thanks!

Composite Forms? Are widgets the right thing to use?
Hi all, I have a sight where I need to generate forms that are made up of two or three other forms. For example I have New User sign up form that accepts user information (user name, name, password), a shipping and a billing address (with the same usual field) and credit card info. Sometimes, I need a composite form with all of the above while sometimes I need a form with just a subset of the information. As an example, I'd like to define a series of forms like this: CreditCardForm - CardType = ChoiceField - CardNumber = CharField - CardExpiry = CharField AddressForm - StreetAddress = CharField - City = CharField - State = CharField NewUserForm - Username = CharField - Password = CharField - ShippingAddy = AddressForm - BillinAddy = AddressForm Is there a way to do this sort of thing with the Forms API? I had hope for FormSets but that's a more dynamic thing that I need which is really a Composite form pattern. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Is it possible to use Django + Postgresql on leopard?
I do *all* my development on OS X Leopard! I just used the version in MacPorts. You have to compile psycopg2 against the same architecture as the server libraries (64 or 32-bit, depending on what you're on). I use a MacBook Pro and I had to add the 64-bit flags. I was going to post what I changed in the Makefile, but I've deleted it. I've used Cygwin a lot and I don't find it easier to use than the Mac at all. Of course, I would say that since I'm a die-hard Mac user. Are you using MacPorts? If so, there's a version in there that will compile fine. I use Postgres 8.3 and I had to make sure my CFLAGS and LDFLAGS were set such that /Library/PostgreSQL8 was found by psycopg's configure. It's called py25-psycopg2. Thanks!

Re: Composite Forms? Are widgets the right thing to use?
Thanks guys! Using multiple forms + prefixes is exactly what I need! Would be nice if there was some global wrapper though so you could do validation amongst the forms but beggars can't be choosers.

Schema Evolution Choices?
Hi guys, I have a small project coming up that I think having some sort of schema evolution facilities will be handy on. I was wondering what the current and best project choices for schema evolution are? I was leaning towards django-evolution until I saw a post from Russell saying that he hadn't updated it to the 1.0 branch yet. Any options or opinions are appreciated.

Re: OT: Google Chrome
I tried it on my Windows VM (still waiting on a Mac version) and it seemed quite fast. Since it's WebKit, I'm hoping it'll be as easy to develop for as Safari. I like that Gears is integrated, though I haven't yet used Gears in an app (it's on my list! :). I'm seriously considering using gears in my admin app for desktop browsers (the nature of the admin interface means you won't be doing much admin on the iPhone...mostly read-only). I think NPR was right about it, when they reported on it this afternoon: most people won't bother using anything other than IE because that's what's installed on their PC and it's what they know (we've standardized on Firefox at work and most people still use IE, though I've convinced some to switch). I can't begin to describe how much I HATE hacking what I write to work on IE. I think that's why I've gravitated to the iPhone. Closed platform or not, it's great to have some stability and predictability as a developer. I've never really had that before and it's kind of nice. Thanks!

Re: Connecting to AS400
I don't think Django can natively use unixODBC as it's ORM backend, unfortunately. It would be great if it did! You could Django without the ORM, of course. To connect from a Win server (why would want to do that? ;), you could use ClientAccess. To connect from Linux, you could use IBM's Linux version of the ClientAccess drivers. All other unices would need the DB2 xpress install, configured to use unixODBC (which works, but to connect one DB2 server to another, you have to pay for the connectivity driver...it's kind of underhanded if you ask me when you can connect on other platforms, outside of the native DB2 driver for free). Or you could use the native Python functionality to use REST-based webservices (Apache/Tomcat come standard, though unconfigured on v5r4, which is what we're running). So there are several options, but not using the ORM, AFAIK. If I'm wrong about that, I'd love to hear it because I could use that as well! :) Thanks!

Re: troubles with mod_python on Leopard
I had quite a bit of trouble with Apache/mod_python on Leopard as well. I had to go back to using the default Apache 2 and stock python 2.5. I also had to rearrange things a bit in the path and ended up putting a symlink in /Library/Python/2.5/site-packges/django to ~/src/ django-trunk/django, which is found by Apache launched by launchd. From there, the basic mod_python directions seemed to work for me. I'm not using Apache any more, though, as I've moved to lighttpd. Thanks!

Deleting a Model with ForeignKey relationship where null=True in Admin causes IntegrityError
See the following set of models: class Mom(models.Model): name = models.CharField(max_length=80) def __unicode__(self): return self.name class Dad(models.Model): name = models.CharField(max_length=80) def __unicode__(self): return self.name class Child(models.Model): name = models.CharField(blank=True, max_length=100) mom = models.ForeignKey(Mom) dad = models.ForeignKey(Dad, null=True, blank=True) def __unicode__(self): return self.name In admin if you create a Child with a Mom and a Dad, and then attempt to delete the Mom, it works as expected (prompt to make sure you're okay deleting the children, click okay, Mom and Child objects are deleted). However, if you attempt to delete the, Dad, you'll get a prompt asking if it's okay to delete the Child but upon clicking Okay, you get an integrity error. I'm using MySQL and innoDB. Here's a link to the traceback: http://dpaste.com/83431/ Is this a bug I'm seeing or am I missing something in either my models or configuration?

Re: Deleting a Model with ForeignKey relationship where null=True in Admin causes IntegrityError
As a note... I've worked around this for the time being by setting cascade on delete explicitly in db. That said, I'd still like to know if this is a bug or if I'm doing something wrong with my models. Jon.

Re: Deleting a Model with ForeignKey relationship where null=True in Admin causes IntegrityError
I was looking for a ticket like that. Unfortunately I could see where either behavior is going to be controversial. If you set the foreign key back to null, some people will want it to be deleted. If you delete, some people will prefer it go back to null. Instead could there be an option on nullable foreign key fields? Default the behavior to the non-destructive setting and then allow people to override it if it should be destructive in their application? Of course, this would amount to introducing a new feature to the 1.0 branch which is probably not what you guys want to do. Maybe a 1.1 feature. I'll shut up now as this discussion clearly belongs in django-dev being discussed by people with more in-depth knowledge than myself ;) Thanks Malcolm. Jon. In the interim, for this project, I'll continue to explicitly set cascading deletes in the db.

Django 1.0.2 runfcgi fails to start on Windows
Hi, all. For various reasons, I prefer to use python 2.6 on my computer. Since mod_python and mod_wsgi won't work on Python 2.6, I have to use FCGI or switch to Python 2.5. I have flup installed without any problems. However, when I try to run this command: manage.py runfcgi method=threaded host=127.0.0.1 port=9000 Nothing happens. I get no status message or anything. If I then run this: manage.py runfcgi protocol=scgi method=threaded daemonize=false host=127.0.0.1 port=9000 I get "WSGIServer starting up", but nothing else happens, and I get server 500 errors from Apache. I know the flup library officially doesn't support Windows, and I also know that there are indications that fcgi simply won't work on Windows at all. But the Django site describes people getting it working on Windows machines. Could someone please help? I don't want to have to switch to Python 2.5 to be able to use mod_python. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Django 1.0.2 runfcgi fails to start on Windows
There are no precompiled binaries for mod_wsgi with Python 2.6. In order to use it, I would have to download the source code for it and compile it against Python 2.6, which I don't think is doable in Windows without making some sort of special adjustments to the source code.

extending admin change_form template
I'm a novice Python and Django programmer so please don't assume a lot of
knowledge here.
I'm trying to place a link on an admin change form to a label printing
function. I'd like to pass the id of the current record to the function. If
I hardwire it in (see below- record number = 920) it works. I can't figure
out how to code this so the current record number is inserted by the
program. Is there some sort of template variable that I can use for this? Or
can you suggest a better approach?
thanks , Jon

I can definitely understand how someone new to the framework, trying to use a custom widget to do HiddenFields (which is more arcane that it should be IMO, but that's off topic) and reading the BooleanField docs could get confused about using them _without a checkbox widget_. I'm going to open a ticket against the doc here and submit a first pass at a documentation patch.

A simple use for multidb... is this possible yet?
Hi everyone (particularly those working on multidb), I have a pretty simple use case that involves use of multidb support and I was wondering if the code base for multidb is far enough along to help me out on this. Basically, I have a legacy enterprise db that I've created working models for using inspectdb. The models work and are a big help in navigating and retrieving the data. What I need to do now is transform some of the data and then store the data in a new set of models in a different database. Of course I could just open another connection using mysqldb and just write raw sql but what would be great is if I could use the django ORM to manipulate the data from the first database and then store it in the second. My question is this: is there enough work done on multi-db already that maybe with maybe a little hack or two I could accomplish this?

You don't need to delete your entire database; it might be worth checking out the management commands ./manage.py sqlreset and ./manage.py reset. These commands drop the tables for a single app and re-creates them, but will leave your auth tables intact, so you don't need to re-create your superuser. --Jon --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Passing an object between views

How to save the data from a form to my db.
Hi all,
I have the a from with the following validated data posted to itself
(copied from the POST section on the error page):
cru'008'
description u'asdfs'
file u'suus'
I am trying to save it to the database. The variable names are the
same as the column names in the database. How can i go about this? I
tried various things with .save(), but that didn't work yet.
I also tried doing it using cursor.execute (with only one value for a
start) but that resulted in the error ''unicode' object has no
attribute 'items''. I used this statement:
cursor.execute("insert cr into editor.conffile values('%s')", cd['cr'])
The following failed with "global name 'cr' is not defined"
cursor.execute("insert cr into editor.conffile values('%s')", cr)
Thanks in advance for your help!
Jon.

How to pass variables from a different file to via a view to a template?
Hi list,
In an attempt to follow the DRY principle and keep environment
specific variables separate from my application code, i decided to put
a number of application specific variables in a different file.
So i have a file like this:
---
u...@host:~/program$ more appenv.py
##
# app environment specific variables
##
page_list = ('index','editor','upload')
server_list = ('localhost','remotehost')
---
This file will hold more variables, but for the sake of simplicity, i
just show two here.
In the beginning of my views.py i did an import:
from app.appenv import page_list, server_list
I have several views where the server_list tuple is used inside the
view definition.
That works fine.
The page list, however, is only read by the template.
I always pass locals() to the template and when defining server_list
inside the view definition, that works fine; the template can access
it. The following line however, doesn't work for me:
return render_to_response('static', locals(), page_list)
My question is twofold:
1) How do i add page_list to locals()?
2) What can i do if i don't want to pass locals(), but more than two
arguments to render_to_response?

Re: How to pass variables from a different file to via a view to a template?
Since nobody responded, i figured i should revisit the documentation.
Here are the answers to my own questions:
1. To add a variable from an external file, i simply redefined the
value page_list inside the view. That causes it to be included in the
local context and added to locals().
In the appenv.py file i simply renamed page_list to pages and in the
view i added 'page_list = pages'.
2. If i don't want to use locals(), i found that i should simply
manually create a dictionary passing all values required.
>From Chapter 7, Forms:
For 1. "[..] locals(), which will include all variables defined at
that point in the function’s execution.[..]"
For 2. "[..] locals() incurs a small bit of overhead, because when you
call it, Python has to create the dictionary dynamically. If you
specify the context dictionary manually, you avoid this overhead."
Django has great documentation.
One remaining question for people who have vast experience creating
reusable django applications, is if the appenv.py file is a good
approach if my goal is to write django applications with reuse in
mind.
Thanks in advance for your response.

Dynamic Form Widget [django admin]
Hi guys, This might be best explained by example... for the following model: class Setting(models.Model): data_type = models.CharField() value = models.TextField() I want Django's admin to display a different form widget for the "value" field depending on the input of "data_type". For example: if "data_type" was "date", then the value field would use a date widget instead of the TextField's default widget. My predicament is that ModelAdmin is defined as a class, and not instances. So I can't pass it a custom form since instances (i.e. "data_type" value) are needed to decide what field the form should have...

another subfolder). To urls.py I have added:
urlpatterns += patterns('',
(r'^static/(?P.*)$', 'django.views.static.serve',
{'document_root': settings.STATIC_DOC_ROOT}),
(r'^admin/', include(admin.site.urls)),
)
To settings.py I have added:
STATIC_DOC_ROOT = '/Users/jonno/django_projects/MCOd/static'
This is what it says to do in the above referenced Django
documentation. Nothing is mentioned about MEDIA_ROOT or MEDIA_URL, so
I have left them intact (''). Many posts mention putting paths there,
but not the Django doc. I didn't want to try the django-staticfiles
packages as I understand this is folded into newer versions, so I'll
deal with changes in an upgrade. I'm really only trying to add a
little Django functionality to an existing static site, so dealing
with my vast number of static files easily is crucial. Of course, my
plan is to generate more of my site dynamically over time. I just
can't get past this point! Thanks for any help -- Jon.

Template and Form Question
Folks,
I would appreciate some help figuring out how to create a
templated form scenario. The quick form of the question is
either:
How do I iterate over two form field list simultaneously
in my template using {% for f in form %}, sort of like
{% for f,g in form1,form2 %}?
or
How do I iterate over a list of strings and use that to
select form fields in my template?
Gory details of and failed attempts follow...
I have a dynamically created form, attr_form, that derives
its fields from a query and adds pairs of fields to the form
roughly like this in my forms.py:
def create_attribute_form():
class AttrForm(forms.Form):
for every DB Attribute field, attr, on something:
name = attr.name# Eg: "Volume"
units = "%s-units" % name # Eg: "Volume-units"
self.fields[name] = forms.FloatField() # Eg, "17.0"
self.fields[units] = forms.ModelChoiceField(...) # Eg, "Liters"
In my view, I trump up this form and hand it to my template in
a context as "attr_form". I know this form gets to my template
correctly because I can simply place {{ attr_form.as_p }} in it
and all the fields are present. They are just not how I want
them arranged.
Specifically, I want to arrange them into a table like this:
Attribute| Value | Units
-|---|-
Temperature |70 | C
Volume |17 | Liters
Which means I need to iterate over "Volume" and "Temperature"
attribute names, and locate the "Volume" field and then the
"Volume-units" field of my form in order to form one row of
the table before going on to the next.
If I just iterate over the attr_form straight up, I will see
all the attributes, of course.
So I kind of want to do this (not working) in my template:
with:
{{ attr_list }} == [ "Volume", "Temperature" ]
{{ attr_form }} == The form instance with pairs of fields in it
.
{% for attr in attr_list %}
{{attr}}
{{attr_form.fields.$attr.}}
{{attr_form.fields."$attr"-"units".}}
{% endfor %}
Naturally that $attr and constructing that $attr-"units" thing
is totaly bogus. But even if I passed in a list of tuples
with ("Volume", "Volume-units") in it and looped over that,
I still can't use those for-loop-variables to index into the
form's fields[] to get and print the fields!
So another approach I tried was this: In my view, create a list of
triplets with:
("Volume", , )
and pass that into the template as "attr_trio":
.
{% for a,v,u in attr_trio %}
{{a}}
{{v}}
{{u}}
{% endfor %}
This *almost* works, but what I get is a table like:
Volume object at 0x2768910>
Temperature object at 0x2768050>
That looks like the v and u parts are either un-instantiated,
or being processed differently, or un-bound, or *something*...
As another approach I've explored unsuccessfully so far,
I've tried to create two forms: one with the Attribute fields
and another with the corresponding Units fields. I can pass
both those into the template, but now I need a way to iterate
over the attr_form and units_form simultaneously so that I
can grab a "Volume" and a "Volume-units" field for one row.
I have the itertable list of ["Volume", "Temperature", ...] available,
but I don't know how to use that iteration variable name to select
the form field from the two forms:
with:
{{ attr_list }} == [ "Volume", "Temperature" ]
{{ attr_form }} == The form instance with just Attribute fields
{{ units_form }} == The form instance with corresponding Units fields
.
{% for a in attr_list %}
{{a}}
{{attr_form.a}}
{{units_form.a}}
{% endfor %}
Even that glosses over the problem of having a form with two
fields labeled with the same name. I'd really have to loop over
a tuple of ("Volume", "Volume-units") like:
{% for a,u in attrunit_list %}
...
{{a}}
{{attr_form.a}}
{{units_form.u}}
But none of that works either.
OK. Any chance someone can point out the forehead-slapping
obvious solution for me? Or point me in the right direction?
Should I give up on doing this in the template and somehow
render the whole form into a string in the view and pass that
into the template to slap it down? Does that violate some
large abstraction separation? :-)
Thanks,
jdl

So, for the record, I failed to get any form of proper
template variable use or lookup to do what I needed.
However, I was able to achieve success in my table construction
using the following custom template filter as found here:
http://diffract.me/2009/09/django-template-filter-show-list-of-objects-as-table-with-fixed-number-of-columns/
File: my_filter.py
from django import template
register = template.Library()
def tablecols(data, cols):
rows = []
row = []
index = 0
for user in data:
row.append(user)
index = index + 1
if index % cols == 0:
rows.append(row)
row = []
# Still stuff missing?
if len(row) > 0:
rows.append(row)
return rows
register.filter('tablecols', tablecols)
and then in my template:
{% load my_filters %}
and:
{% for row in attr_form|tablecols:2 %}
{% for f in row %}
{% if forloop.first %}
{{ f.label }}
{% endif %}
{{f.errors}}{{f}}
{% endfor %}
{% endfor %}

State of the Django MPTT Art?
Folks, I'd like to add a few MPTT manged data-sets to my projects so I am wondering what the current state of the MPTT art is. I'm using Danjgo 1.1.1 right now, and would like to slap down an MPTT manager in my project that is BSD-ish licensed, allows multiple, different sets of nodes, and hopefully comes with a good admin interface too! Googling shows both django-mptt and -treebeard, but are there good recommendations pro- or con- for either one? Or is there a better third choice out there now?

I also had difficulty even with the suggested d.v.static.serve
as suggested above. I had to change the ADMIN_MEDIA_PREFIX in
my settings.py to be different from MEDIA_ROOT as well.

AJAX Autocompletion Field
Folks, For likely the umpteenth time, can someone recommend a good AJAX auto completion tutorial or example that I might use to crib-together a text-field selection that would otherwise be a very large drop-down selection field? My use case would be essentially like having a table full of say, recipie ingredients, and letting the user select which one to add into a recipe. I'd like to have the user simply start typing a few first characters and then let an autocompleter search for matches and present them to the user. The source of the matches would be a "Name" TextField in some model. What is the current Best Practice or even Good Advice? :-) Pros and cons for jQuery or extjs or something else? A good "How To" or a pointer to a write up? Thanks, jdl -- You received this message because you are subscribed to the Google Groups "Django users" group.

Slugify() and Clean form data Questions
Folks, Quick question or two: Is there a canonical definition or even a reference implementation of a slug = slugify(str) function somewhere? Yeah, I could go grep through the sources and maybe find one? And yes, I see: http://docs.djangoproject.com/en/dev/ref/models/fields/#slugfield But even that is a bit ambiguous as to the treatment of underscores. Naturally, I'm wanting to use a slug to identify some model instances based on some other model field. But it's not being entered via the Admin model, so I can't do the prepopulated_fileds[] trick either. Second question: Is there a standard clean_user_input() that accepts direct user input from a form text field and de-gunks it so that it is later acceptable to be re-emitted as HTML formatted data without worry of hacking issues? I am looking form something more clever than simply validating the user's input to conform to "is a number" or "is a text field" sorts of thing. I'm specifically looking for a function that strips out embedded scripting, SQL, HTML, etc hackery. Sure, I'd then like to use it to verify clean form input of course.

Converts to lowercase, allows dashes and underscores, removes other non-alphanumeric characters, and converts spaces to hyphens. Also strips leading and trailing whitespace.

Re: Slugify() and Clean form data Questions
> > Hope this better answers your question, > Matt Matt, Indeed it does. Thank you! I guess a bit of the frustrating part of learning Django here is stumbling across the sites that explain how to do various tidbits of functionality, and then slide in some variant [*1*] of "But one would never do this on a production site." warning. I think to myself "But this is *exactly* the functionality I need." So, uh, what *should* I do differently then? Or, um, OK, so, why not take the next step in the write-up and tell me what the best practice is so I *can* "do this in a production setting." I read chapter 20. And when I was done, I had an inkling that Django escaped my user data when it went to HTML output. Good. And I read where "Django's API does this [escape SQL] for you". But what wasn't clear to me was how much *more* I really should do. How worried should I be? Should I write better form cleaning and validating functions? Should I write custom save() functions to search for SQL or script hacks? That sort of thing. And from the sounds of it, you are saying Django has taken large and likely sufficient steps already.

First match wins, right?
A lacking $ in the first people rule will match
with a trailing number as well.
So I think you can solve yuour problem by either switching
the order of the people patterns or add a trailing $ to the
first rule: r'^people/$'.

Django advocacy in a commercial environment
Hello, Having just finished a couple of large projects in PHP4, our department (of 5 programmers) is looking to move to PHP5 - but me and another on the team have been pushing towards using Python/Django in future. While everyone sees the benefits of moving to Python (namespaces! enforced syntax! and more!), it would help us immensely if we could find some resources to wow the other programmers here. I was fortunate enough to attend Simon Willison's excellent talk at LUGRadio Live 2006, which really inspired me to start using Django, but short of inviting him here (and probably paying him), I'm not sure I could recreate that kind of convincing argument myself. Which leaves us with online resources, presentations, screencasts and suchlike. If anyone has any good resources which show off the power of Django (and by association, the benefits of PHP), then please share them with us.

Re: Django advocacy in a commercial environment
Thanks for your reply, Rob. Personally, the reason we're looking to push Django is that our business needs very much match a statement Simon made in the talk I mentioned above: 'Web development on journalism deadlines' (that might not be entirely accurate). I was also considering putting together a report, but we all know the problems with code metrics - do we measure LoC, speed of development, or the very nebulous 'simplicity' concept which will be quite difficult to communicate to management. I don't mean to pry, but at your workplace have you had any difficulty hiring into Python/Django roles at your company (compared to PHP)? Do you get less applicants? A better quality of applicant?

Questions regarding contrib.sitemaps
Hello, I'm trying to implement the a sitemap.xml file using the contrib.sitemaps framework. It's pretty simple to use, but the output I'm getting is not correct. My code in sitemaps.py is as follows. Notice I've used the optional location() method.: from django.contrib.sitemaps import Sitemap from jonatkinson.blog.models import Post class BlogSitemap(Sitemap): changefreq = "weekly" priority = 0.5 def items(self): return Post.objects.all() def lastmod(self, obj): return obj.date def location(self, obj): return "/blog/%s" % obj.slug And a snippet of the output I'm getting is: http://example.com/blog/ghetto-backup 2007-06-25 weekly 0.5 http://example.com/blog/removing-.svn-from-a-subversion-repository 2007-05-25 weekly 0.5 As you can see, the locations generated includes 'example.com', which is not correct. According to the documentation, the location method is supposed to "URL that doesn't include the protocol or domain"[1]. I'm guessing that the sitemaps framework is somehow tied to the sites framework. Has anyone else come across this issue before?
