Accidentally creating a model with "def unicode(self):" will crash django with no stack trace
This might seem obvious, and I just spend a couple hours straining over it, so I thought I'd share. If you have a model, e.g.: def MyModel(models.Model): # ... # with a unicode function likeso: def unicode(self): return 'something' This will crash Django, without a stack trace. Of course, the function is supposed to be "def __unicode__(self):", but it'd have been awful nice to be able to figure that out without rehashing the entire codebase (it seems like such an innocuous addition to the model at the time haha). Hopefully this will save someone some pain. :) All the best, Brian --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Accidentally creating a model with "def unicode(self):" will crash django with no stack trace
I should be more precise. :) Here's a simplified excerpt of the
problematic code - when a Django (1.0) template tries to turn it into
text with its default unicode function, Python (2.5.1) crashes (on Mac
OS X 10.5):
from django.db import models
from people import Person
class Letter(models.Model):
to = models.ManyToManyField(Person, related_name="%
(class)s_related")
author = models.ForeignKey(Person)
content = models.TextField()
def unicode(self):
date = unicode(self.dated)
author = self.author
to = ", ".join([ unicode(r) for r in self.to.all()])
return "Letter dated %s from %s to %s" % (date, author, to)
@models.permalink
def get_absolute_url(self):
return ('letter_detail', [self.pk])
The fix being, of course, changing "unicode" to "__unicode__".

Configuring multiple Django installs transparently via FastCGI mutiplexing
Hi everyone, Here's a questions I just posted on stackoverflow.com (because I like that forum's layout) - but I thought posting it here might lead to more / better coverage. See: http://stackoverflow.com/questions/322694/ Multiple installs of Django - How to configure transparent multiplex through the webserver (Lighttpd)? Hi Everyone, This question flows from the answer to: How does one set up multiple accounts with separate databases for Django on one server? (http:// stackoverflow.com/questions/314515) I haven't seen anything like this on Google or elsewhere (perhaps I have the wrong vocabulary), so I think input could be a valuable addition to the internet discourse. How could one configure a server likeso: * One installation of Lighttpd * Multiple Django projects running as FastCGI * The Django projects may be added/removed at will, and ought not to require restarting the webserver * Transparent redirection of all requests/responses to a particular Django installation depending on the current user I.e. Given Django projects (with corresponding FastCGI socket): * Bob (/tmp/bob.fcgi) * Sue (/tmp/sue.fcgi) * Joe (/tmp/joe.fcgi) The Django projects being started with a (oversimplified) script likeso: #!/bin/sh NAME=bob SOCKET=/tmp/$NAME.fcgi PROTO=fcgi DAEMON=true /django_projects/$NAME/manage.py runfcgi protocol=$PROTO socket= $SOCKET daemonize=$DAEMON # end I want traffic to http://www.example.com/ to direct the request to the correct Django application depending on the user that is logged in. In other words, http://www.example.com should come "be" /tmp/bob.fcgi if bob is logged in, /tmp/joe.fcgi if joe is logged in, /tmp/sue.fcgi if sue is logged in. If no-one is logged in, it should redirect to a login page. I've contemplated a demultiplexing "plexer" FastCGI script with the following algorithm: 1. If the cookie $PLEX is set, pipe request to /tmp/$PLEX.fcgi 2. Otherwise redirect to login page (which sets the cookie PLEX based on a many-to-one mapping of Username => PLEX) Of course as a matter of security $PLEX should be taint checked, and $PLEX shouldn't give rise to any presumption of trust. A Lighttpd configuration would be likeso (though Apache, Nginx, etc. could be used just as easily): fastcgi.server = ( "plexer.fcgi" => ( "localhost" => ( "socket" => "/tmp/plexer.fcgi", "check-local" => "disable" ) ) ) # end Input and thoughts, helpful links, and to know how to properly implement the FastCGI plexer would all be appreciated.

Re: Configuring multiple Django installs transparently via FastCGI mutiplexing
Hi Graham, Thanks for the reply. No, I'm not stuck using Lighttpd at all - I just like it because it's simple and fast. :) Here's a link to a description of what I'd like to see: http://stackoverflow.com/questions/314515 The situation is this: I'm creating a web-site with a bunch of accounts - each account having its own database. I want people to go to the site (i.e. www.example.com/) and when they log in the application gets all its requests/responses from their account's database. For the moment, all accounts will be using the same Django applications, though that is subject to change so I'd prefer not to rely on a solution that precludes that possibility. I suspect (but am happy to be corrected...) that the easiest and safest way to do this is to have a Django instance running in FastCGI mode with a socket for each account. When a user is logged in, their requests/responses are mapped to/from the proper Django socket via the multiplexing solution I've suggested in my original post. As mentioned, accounts may crop up and disappear, and shouldn't require restarting the web-server. There could be dozens of accounts (which means lots of Django instances). Is there any more information that would be helpful?

Re: Configuring multiple Django installs transparently via FastCGI mutiplexing
Accounts could be created as often as hourly. I'd be very bad to have the webserver go down while people use the system (unless it was for less than a second or two... but even then, it's still be very bad :) ).

Re: Configuring multiple Django installs transparently via FastCGI mutiplexing
fferent mechanism than the accounts' respective databases. That's easy enough thanks to the delightfully decoupled user authentication system in Django. I hold out hope that there is a brilliant, simple solution to this problem via Django. However, my searches and inquiries suggest that it's not a common problem, nor especially obvious. Failing a safe, sensible way to change the database settings in a running Django process (or some other intelligent way to demultiplex user requests to their respective datasets; essentially semantic, mutually exclusive sharding), I believe you've astutely pointed out that this isn't a Django issue, and I should meander over to the webserver forums. I'd prefer a Django solution to a webserver one, though, because it's the right place to do it. I hope that clarifies the explanation some, and makes this vein of inquiry of some value to the body of Django knowledge. If it's not something that's a workable Django solution, I'd be happy to have some certitude about that, too.

Re: Configuring multiple Django installs transparently via FastCGI mutiplexing
Hi Graham, Sorry I didn't respond earlier - for some reason your last reply with the questions didn't show up until late today. Very odd -- didn't mean to ignore your question or give the impression that I was ignoring it. I most certainly am interested in potential solutions. > I don't know how lighttpd works, but if one does a graceful restart > (or even a restart) with Apache, in the main it isn't noticeable to > the user as the listener socket is never released and so new > connections just queue up and aren't outright refused, ie., server > isn't actually completely stopped.

This is > because on a restart, active instances which are still required are > restarted regardless. I know little about webservers, but I'm relieved to hear that the restarts are graceful. I believe this gracefulness was a recent addition to Lighttpd, also. Incidentally, I simply chose Lighttpd because I've never used it before, and I figure it'd be fun to learn how to set it up. I would think the Django processes ought to be persistent in the background (unless the webserver is starting/stopping them). > The actual Django application is something the users themselves are > just a user of?

This is a good question, and I haven't come to a conclusion. Probably it'll be the Django built-in application-based authentication, particular to each Django instance. There will be a master map of all users to their respective Django instance. > Does the account have a distinct UNIX account associated with it, or > would all Django instances run as same user and you are then just > mapping a logical account name to a specific instance attached to a > specific database. I'm thinking they'll all run as the same Unix user, and it's just a logical mapping from an account to a database.

If usernames are unique, e.g. email addresses, there can be a map, e.g.: [EMAIL PROTECTED] => DjangoInstanceA, [EMAIL PROTECTED] => DjangoInstanceB, This User-Instance mapping could happen prior to authentication if, when the user submits login-information from a form, a process (demultiplexer) decides based upon the username which Django instance to direct the login-request to. The Django instance then handles all subsequent requests.

Beginners questions on forms containing multiple related model types.
Hi,
I'm new to django and have been working hard to find "the right way"
or at least "a good way" to do things. I'm running into a few
problems though that I can't get answers for.
The following post describes my situation very clearly. It may be
long-winded but hopefully it's unambiguous. I'm sure there'll be
nothing difficult to the experienced django user here, but some
answers could be helpful to me and other beginners.
In my django model I have the following classes: Person and
BankAccount. There are other model types too, but these should
suffice to illustrate my problem.
Person:
person_id
first_name
surname
BankAccount:
bank_account_id
person_id (ForeignKey)
bank_code
account_number
A Person may have ZERO or ONE BankAccounts.
I want to be able to create or edit the details for a Person
(including their associated BankAccount, should it exist) on the one
html form. I've created some ModelForm types to help with this:
class PersonForm(ModelForm):
class Meta:
model = Person
class BankAccountForm(ModelForm):
class Meta:
model = BankAccount
exclude = ('person',) #Avoid the dropdown menu
I've been advised (on IRC #django) that "create new" should be handled
at one URL and "edit existing" at a separate URL. I handle the URLs
at different view functions. So in url.py:
url(r'person/add/$', 'person_add', 'person_add'),
url(r'person/(?P\d+)/$', 'person_edit',
name='person_edit'),
The "person_add" view function is easy to implement. For request.GET
for I simply create a new PersonForm and a new BankAccountForm and
expose them to the template via the context. The request.POST is easy
too - however I only save the BankAccount data if non-blank data was
supplied.
The "person_edit" view function raises some problems though:
1) I may be editing a Person that has no associated BankAccount. So
basically I'm supplying a form with "edit existing" functionality for
the Person model and "create new" functionality for the BankAccount.
This doesn't cause a problem in itself, but it does break the paradigm
of separating "create new" and "edit existing" functionality - if such
a paradigm is indeed correct.
2) When a GET request to /person/5/ is received, I retrieve the
relevant Person from the db. In a separate db query I then have to
try to get an associated BankAccount. If I do:
BankAccount.objects.get(person=person_id)
and the BankAccount doesn't exist a DoesNotExist exception is
thrown... This really surprised me. Thinking about it from a db query
perspective I would have expected an empty list. I notice however if
I do:
BankAccount.objects.filter(person=person_id)
I receive an empty list when there is no match. I presume this is by
design, I just wonder what the logic of that design is. Any ideas?
3) When a POST request to /person/5/ is received the URL tells me I'm
editing Person "5", but I also need to know if I'm editing or creating
a BankAccount too. I can obviously query the BankAccount table for a
record matching person_id=5, but again there is a db roundtrip
overhead here. Alternatively, I think I could have included a hidden
bank_account_id field when I received the GET request for /person/5/
so that upon POST I would "know" the bank_account_id - with some
security concerns though. What is best-practice in this situation?
4) You might notice that the relationship between Person and
BankAccount is modelled as a One-To-Many, however my business logic
requires One-To-(Zero or One). I wondered if I could use the
models.OneToOneField for this, but the documentation seemed to imply
that django would expect exactly one record on BOTH sides of
relationship, so it may not be suitable for the One-To-Zero case.
Again, if anyone has advice on what I should actually do here, please
let me know.
Obviously this is a simple example and I could code a solution that
would work. However, my real problem involves several similar
relationships on the one form. The POST handling code could get very
hairy if I don't do it well.
If you got this far, thanks for taking the time to read this.

no objects found
Django 1.0.2-1 If I do: >>> object=models.software.objects.get(id=267) >>> print models.software_installation.objects.filter(software=object) [] >>> print models.software_installation.objects.filter(software=object).count() 10 Huh? First statement says there are no results, next one says there are 10. If I spy on the packets, I see this in the SQL for the first statement: ... LEFT OUTER JOIN `inventory_license_key` ON (`inventory_software_installation`.`license_key_id` = `inventory_license_key`.`id`) INNER JOIN `inventory_license` ON (`inventory_license_key`.`license_id` = `inventory_license`.`id`) ... If I remove the inner join part (and the reference to it in the order part), and run the SQL on the server, then it works. `inventory_software_installation`.`license_key_id` == NULL on the rows in question (the model specifies null=True). I have a suspicion that the above SQL doesn't work because it requires a inventory_license object, however there is no inventory_license_key object there is no inventory_license object. The relevant definitions (I can provide more details on request) are: class software_installation(models.Model): [...] software = models.ForeignKey(software) [...] license_key = models.ForeignKey(license_key,null=True,blank=True) [...] class license_key(models.Model): [...] license = models.ForeignKey(license) [...] class license(models.Model): [...] Any ideas?

Django crashes Python without traceback on Mac OS X (Release 1.0)
Hi there, Django is crashing Python on my machine for one particular application of my Django project (the other applications are unaffected).

Model Form Field Ordering
I have a ModelForm subclass where I define a special field. How do I
make that special field appear first in the rendered form (using a
form.as_* method)?
Here is an example:
class MyModelForm(forms.ModelForm):
mySpecialField = forms.ChoiceField(label='Special', choices=(('a',
'aa')))
class Meta:
model = MyModelType
The problem is mySpecialField is rendering last, but I wish it to
appear first.
Thank you for your assistance.

Bookmark URL with form data
My experience level: basic. I'm not a developer by trade and do it as a hobby. I'm pretty familiar with basic web development--HTML, CSS and js. I have explored PHP and other technologies to improve my development. Now I've started developing using Django+App Engine Datastore. I've got an application to do various things working-- submit data, delete data, edit data, view data, etc. Right now I'm stuck on something that seems like it should be relatively simple... On my index page I have a search form (along with data and other stuff). I've got it so the user can enter a search, select type, and then get data and other stuff on a new page. Form field IDs are id_search and id_type. Action is "/search/". On the results page I'd like the URL to include the search data so the user can bookmark this and open it at a later date. I've read various topics on the django approach to formatting URLs to make them more readable and to put thought into the best long-term approach. I haven't been able to figure out how to change the URL that shows up in the browser to include the search data. I'm pretty sure I can handle this bookmark URL through URLCONF once I get to that point. Please direct me to some reading to get me through this--I'm probably not using the right search terms for this topic when I google.

Saving Deserialized Objects -- Help Needed
I'm having trouble saving deserialied model objects. My setup is that I have two django instances, let's call them A and B. The intial request comes into server A which then serializes some objects and sends them off to server B for the results of some computation. When server B tries to save the objects sent by A it fails. I believe the save is failing because the objects already have primary keys set from server A's database, but are not contained in server B's database. I could be wrong that this is the reason. Both django instances are operating the same projects with the same models. I do need the objects saved, since their relationships are described in their foreign key relationships, that are used for the computation. Any assistance would be very appreciated.

Re: Running Django on Tornado's HTTP server
I have a small Django app under development and was able to get this running using the github update. My app runs and is very responsive with Tornado. Some of my admin site layout is out of whack, but it may be my settings or my bug. Formatting and CSS I created on my own looks good (e.g. graphics and tables created using the Google Visualization API.) My app is able to go out onto the web, get files downloaded through Tornado - it feels fast ... It's terrific to have a Python-based server that could work in both development and production. (Tornado installs/runs fine on a Netbook with Ubuntu!) The real-time / asynchronous capabilities look great. Any way Django apps can take advantage of that functionality?

Re: Running Django on Tornado's HTTP server
Thanks ... this link pointed me in the right direction. Should I be able to serve up admin media using just Django and Tornado? If so, I haven't found the right combination of paths / urls etc. in settings.py to get that working. The Tornado doc describes how to "serve static files from Tornado by specifying the static_path setting in your application" - so it sounds like it might eventually work? The Tornado blog demo is one example, but I couldn't get that approach working with my Django app. I now have nginx serving up the Admin files, running alongside Tornado and Django. My Admin Site formatting and layout looks fine with that setup. -- Brian On Sep 15, 6:26 am, fruits wrote: > media files for admin is handled by the django dev server.

Thank you, Thanks you, Thank you.
{% include inpage.footer %} works just fine. The {{}} is unnecessary
as I had it.
Sometime the brain is not working.

Empty QueryDict on POST
Hello! I could use some help tracking down a problem here. I have a view that starts as follows: @login_required @json_response def save_exercise_week( request, week_id ): formID = request.POST['formID'] But this returns a 500 error because the QueryDict is empty -- MultiValueDictKeyError at ... "Key 'formID' not found in " In fact, according to the Django error page, there is no GET, POST, or FILES data. I've checked my HTML form over several times and it looks fine. In Firebug, it says the POST sent is: csrfmiddlewaretoken: ... fatPercentage: 10 formID: formWeek4 weekNumber: 17 weight: 150.0 year: 2010 which is correct. So, it looks like somewhere between the sending of the request and the calling of the view, the POST data is lost. I am using an XHR request to retrieve this view, but that's working fine for other views in my project. I would appreciate any ideas about what might be causing this.

move up tree in {% include "/dir/name.html" %} statement
Thanks for the help.
I'm using Python 2.5 and Django Template 1.1
I can't seem to move up the directory tree for inserting of html files
using {% include file %} statement
Sample dir structure:
---/lib/Top.html
---/lib/
root/
---/main/
---/main/include/HomeLogo.html
---/main/HOME.html
Inside HOME.html I can use {% include "/include/HomeLogo.html" %} =
Works just fine to any where up the tree.
BUT
I can not find a way to include the top.html file in home.html.
I tried {% include "/lib/Top.html" %}, {% include "lib/Top.html" %} ,
{% include "../lib/Top.html" %}, {% include "./lib/Top.html" %}
can not find a way to insert the html in.
Thanks again.

Re: Can't move down then up the directory tree for inserting of html files
Dan, Thanks for the reply.
I just can not get it to work. Works just fine in same or any
directory under the dir that the .py file is in.
I played with TEMPLATE_DIRS setting without any luck, tested to the
root dir and still does not work even with "../Top.html" in the dir
under it.

Re: Can't move down then up the directory tree for inserting of html files
Thanks for the help, Still can not get it to work.
I changed TEMPLATE_DIRS setting 30 ways.
I can't seem to move down the dir tree for inserting of html files
using {% include "file" %} statement, Works just fine to any where up
the tree, i can go up 3,4 levels just fine, but can not go down even 1
{% include "../LOGO.html" %}
Sample dir structure:
root/lib/LOGO.html (1 level down then 1 level up, not working )
root/LOGO.html (1 level down, not working)
root/main/home.html <--tried: {% include "../LOGO.html" %} ,{% include
"root/lib/LOGO.html" %} , {% include "/root/lib/logo.html" %}
root/main/start.py
root/main/LOGO.html (works fine)
root/main/include/LOGO.html (works fine)
To test I put just directory text inside the html file so I know what
is displaying
Thanks.

Re: Can't move down then up the directory tree for inserting of html files
Daniel, thanks for the help!, I really appreciate it.
Believe me, I simplified this to nothing:
1) I have LOGO.html in all directories with only the current directory
name in the html file (/lib = directory of LOGO.html file)
2) the home.html file has about 30 deferent include statements so I
can see from what directory its included the LOGO file from. ( {%
include "LOGO.html" %}, {% include "/LOGO.html" %} {% include "lib/
LOGO.html" %} {% include "/lib/LOGO.html" %} etc
3) I tried TEMPLATE_DIRS setting 30 ways:
Currently:
SITE_ROOT = os.path.realpath(os.path.dirname(__file__))
TEMPLATE_DIRS = ( os.path.join(SITE_ROOT, ''),
The log file is showing the correct root path with this but I tried
coding this 20 ways, including; 'root', c:\root, /root, \\root, "../",
"lib", /lib", "/", "\\"
I hate waisting time on this as I could be more productive coding, but
I will try a new project with this on Monday, someone also said
something about Python 2.6 being better at relative paths.(I'm on 2.5
with 1.1 of templates)
FYI: I have no problem including .py code from all kinds of relative
paths down & up the tree.
Thanks again.

Re: Can't move down then up the directory tree for inserting of html files
Tom
1) the LOGO.html file contains the name of the directory it's in. (ex:
Logo.html in the root will display C:\ROOT) So when I run the web page
it displays all the Logo files that got included. When I run I have
multiple Logo files from up the tree but none from down.
2) I tried multiple tuple values in the TEMPLATE_DIRS, I tried 30
value with forward and backward / & \, I like to go to the root with
relative path.
3) Performance is not a issue, just trying to get this to work.
Thank for the info.

Re: Can't move down then up the directory tree for inserting of html files
Tom, Thanks again.
If so, stop trying - you cannot do --> just to be clear:
I like to do this:
src
├── settings.py
│
├── templates
│ ├── logos
│ │ ├── logo1.html
│ │ └── logo2.html
│ └── titles
│ ├── title1.html
│ └── title2.html
├── main
│ ├── page.html <-- in here I like to say {% include "../templates/
logos/logo1.html" %} or {% include "templates/logos/logo1.html" %}
│ └── start.py (runs application and calls page.html)
Thanks Brian

No module named urls
Hi all,
I'm putting together a Django application from scratch and have
created my models. I'm trying to activate the admin site now and am
getting the above error. I've tried everything I found on mailing
lists with no luck. This includes the old style settings.py (which is
commented out now) as well as the new. Note, the model has synced to
the database correctly.
Here is the contents of the admin.py file which resides in my app
directory (triagedb/triagedb_app):
from triagedb.triagedb_app.models import Address, TriageGroup, Nurse,
PhysGroup, Physician
from django.contrib import admin
admin.site.register(Address)

Re: Possible bug with django 1.2, postgresql and aggregates?
It may indeed be that the MAX clause is using "mat_foo" instead of the
assigned correlation U0. What happens if you paste the two SQLs into a
query window in PgAdmin 3 and execute them. If the 1.2 query fails
with the same error message, I'd report a bug.
If it doesn't fail, it's still a Django issue, but I have no idea what
it could be. I'm very new to Django; not new to databases.

Re: Complex Django Hosting
I've been a Slicehost customer for about 3 months now, and will second the recommendation. Granted, I only run Django in FCGI mode with lighttpd on their 256 slice, but they've been extremely reliable, and it "just works." If I needed to host something larger, I'd definitely use them. The fact that they don't oversell (or at least they say they don't) makes it much more responsive than my previous VPS host, where the servers would slow down over time as they'd continue piling the customers on.

Re: Render raw image
Have you considered creating a separate view for that particular
image? You'd have a view designed to grab that image and return it
with the proper MIME type. Then you could, in your Welcome method,
return a dynamically generated path to that URL using the reverse()
method, which you'd use in your tag in your template.

Unique Users Per Site in 'users' & 'sites' Frameworks
I'm building an application where each customer has an account in the system. That account has multiple users in it, each with their own username and password. Every account is a separate entity which will have no knowledge of other accounts or their data. Since each customer has their own subdomain, the sites framework seems like it would work nicely as an account model. I'd also like to use the built in user authentication system instead of rolling my own. However, I'm running into a problem: let's say that AccountA (a.example.com) has a user named UserA. How can AccountB (b.example.com) also have a distinct user named UserA? Will I need to set up a whole new database and settings.py for each site?

Caching: Memcached vs locmem
Can someone run down the differences between using Memcached vs locmem? The docs indicate Memcached is "the best" solution, but seems considerably harder to setup.

TypeError: Cannot resolve keyword 'slug' into field
I've searched for this, but people think it is either fixed or very
hard to reproduce. In my case it is 100% reproducible, and I wonder if
it is my own fault.
I have a model for a mp3 set (a set of mp3s). Individual mp3's are
associated with the set via a Foreign key.
I recently added a slug field to the mp3 after the fact, and I think I
have manually added it to the MySQL database to match what Django
thinks should be there. Now, when I try to edit a mp3 set in the admin
page and hit save, I always get:
TypeError at /django/admin/band/mp3_set/3/
Cannot resolve keyword 'slug' into field. Choices are: mp3, id, date,
title, text
Here are the models:
class Mp3_Set(models.Model):
date = models.DateField(auto_now_add = True, editable = False)
title = models.CharField(max_length = 64)
text = models.TextField()
def __unicode__(self):
return self.title
class Admin:
list_filter = ('date', )
list_display = ('title', 'date')
class Meta:
ordering = ('date', )
verbose_name = "MP3 Set"
class Mp3(models.Model):
mp3_set = models.ForeignKey(Mp3_Set, edit_inline = models.TABULAR,
num_in_admin = 5, num_extra_on_change = 5)
title = models.CharField(max_length = 64, core = True)
desc = models.CharField(max_length = 128, blank = True)
file = models.FileField(upload_to = 'mp3s/%Y/%m/%d/')
slug = models.SlugField(unique = True, prepopulate_from = ('title',
'desc'))
def __unicode__(self):
return self.title
class Admin:
pass
class Meta:
ordering = ('title', )
verbose_name = "MP3"
And here is the export SQL for the two tables:
CREATE TABLE `band_mp3_set` (
`id` int(11) NOT NULL auto_increment,
`date` date NOT NULL,
`title` varchar(64) collate latin1_general_ci NOT NULL,

Django developers NYC???
Hi, New to the group. I just took over the website for a smaller, weekly newspaper in NYC, and I am looking at completely rebuilding the system with a Django framework. Do you have any suggestions how I can find a good lead Django developer in NYC. Are there job boards etc, besides this I should check out (I also posted on gypsyjobs)?

Yes it was a type, otherwise nothing would work lol. Thanks for the reply.
Mysteriously it is not giving me the server error. I did simplify the html

updated the view to

results = Player.objects.filter(name__icontains=search_text)
context = {'results': results}
return render(request, 'Striker/players', context)

template tag that iterates over list with for loop
Is it possible to create a template tag that will create a list that a
for loop can loop over? I know I can create a template tag that will
store the list in a variable and then iterate over that variable. I
want to do it in one step.
For example the template tag with be “list_print” that will create a
list. I want something like the following in the template:
{% for a in list_print %}
Below is my code. When I call it the loop never iterates.
@register.tag(name="list_print")
def do_list_print(parser, token):
#test that don't have arguments
try:
tokenList = token.split_contents()
except Exception:
raise template.TemplateSyntaxError("%r tag throw unexpected
exception(token.split_contents)" % token.contents.split()[0])
if len(tokenList)>1:
raise template.TemplateSyntaxError("%r tag does not take
arguments" % token.contents.split()[0])
return ListPrintNode()
class ListPrintNode(Node):
"""

scroll to form on error
I have form that is toward the bottom of a web page. If someone submits some bad data, I want the page to scroll to the form. Currently if the data is bad, I can see the page get refreshed and the browser scrolls to the top of the screen. When I get an error in a submitted form, how do I get it to scroll to the form? I found this [1] where it scrolls after the form is submitted. I only want it to scroll when the form has an error. After the form is submitted successfully, I redirect to a thank you page. One idea I had in the view was to do something like: - if form.is_valid(): …. else: return HttpResponseRedirect(request.path + '#formId') - The form doesn't show the error fields when I do this. Also this seems to break the MTV model since I putting the div id in the view.

Re: scroll to form on error
The redirect method isn't working. I use middleware to insert a form
into the context for each page. When I try to redirect with a
fragment identifier, then the page scrolls but I don't see the form
errors. If I remove the error form redirect then I see the errors but
this removes the scroll.
Here is my code:
---
class reqInfoMiddleWare(object):
"""
inserts the req info form in content and also handles form
processing
based on:
http://stackoverflow.com/questions/2734055/putting-a-django-login-form-on-every-page
"""
def process_request(self, request):
if request.method == 'POST':
form = forms.reqInfo(request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect('/thanks')
else:
#if error then scroll to where the form is
return HttpResponseRedirect(request.path +
'#learnMoreId')
else:
form = forms.reqInfo()
# attach the form to the request so it can be accessed within
the templates
request.req_info_form = form
---
With this, I see the scroll but my form errors aren't being shown. In
my form template I have <{% if form.errors %}>.
If I comment out the line < return HttpResponseRedirect(request.path +
'#learnMoreId')> and the else before it, then I get the scroll but I
don't get the form errors.
I'm developing on Django 1.3.
I don't want to use the iframe since it is going to make resizing the
form for errors difficult. I prefer to stay away from javascript and
ajax if possible. I also thought redirect with just a url was a
shortcut for HttpResponseRedirect so it does the same thing.
Thank you for your help!!

Attach EmailMultiAlternatives message to an e-mail
How do I attached a EmailMultiAlternatives email as an attachment to
another e-mail? I want to create a EmailMultiAlternatives and send
it. Then I want to create another e-mail and attach the previous
email to this one.
For example:
parameterDict = {today:'monday', month:'june'}
txt_content= myCreateTxt( parameterDict )
html_content = myCreateHtml( parameterDict )
clientEmailMsg = EmailMultiAlternatives(xxx, myTxtHtml, ….)
clientEmailMsg.attach_alternative(html_content, "text/html")
clientEmailMsg.send()
own_contentTxt = 'created e-mail with %s'%parameterDict
own_contentHtml = 'created e-mail with %s'%parameterDict
ownEmailMsg = EmailMultiAlternatives(xxx, own_contentTxt, ….)
ownEmailMsg.attach_alternative(own_contentHtml, "text/html")
#this is where problem happens:
ownEmailMsg.attach(clientEmailMsg)
ownEmailMsg.send()
I get the exception 'assert content is not None'. I assume I need to
convert ownEmailMsg to a MIMEBase but I'm not sure how.

run form save in background
I'm having problems with a save method taking too long and the user
thinking there is a problem with the website so they hit refresh which
causes the data to be submitted multiple times.
I have this in the view:
-
if form.is_valid():
form.save()
return HttpResponseRedirect('/thanks/')
-
The save method takes a little time. It saves to db, sends a couple
of emails, and interfaces with another software package(which is the
time hog). I want to be able to show the thanks page and then call
the save method.
It seems like celery(http://www.celeryproject.org/) is the best
choice. When I read the doc it said because of race conditions, be
careful of passing models to celery tasks. With my form I want it to
save a unique instance for every time the form is submitted so I think
I can pass the form to the task.
Does anyone have suggestions or other recommendations about this? Is
there an easier way to do this?

change charfield choices from within a ModelForm
How do I change the CharField choices from within a ModelForm?

test = models.CharField(max_length=3,
verbose_name='test choices',
)
class myForm( ModelForm ):
class Meta:
model = myModel

form. Note: I haven't ran this version of the code.

field._choices = choiceTuple

super(myForm, self).__init__(*args, **kwargs)
choices = (
('a', 'choice a'),
('b', 'choice b'),
)
self.instance.changeChoices(choices)
class Meta:
model =
myModel
--
One thing I thought about was passing a parameter to the model init
but I'm not sure how to do that. I found this article that would seem
to work if I could figure out how to send params to the model's init:
http://blog.yawd.eu/2011/allow-lazy-dynamic-choices-djangos-model-fields/
Another thing I thought about was modifying the field in the form. In
the forms init do something like self.fields[ 'test' ]... but I'm not
sure where to access the choices.

Transition from VPS(WHM/CPanel) to EC2
I'm in the process of transitioning from a VPS (WHM/CPanel) to EC2. I've found some great how to's on setting up a machine for the cloud[1] but I'm not sure the best setup to add some of the WHM/CPanel features. Here are some of the features of cpanel I use: 1. Cpanel monitors the services (i.e. apache) and restarts them if they crash. I'm thinking about using supervisord for this. Does anyone have experience with this or is there other tools I should be looking at? 2. I'm running a custom DNS(BIND). I'm planning on switching to Amazon Route 53. 3. I'm switching to PostgreSQL and I'd like to have something similar to myPhpAdmin. 4. Creating a backup script seems pretty straight forward. 5. What is the best way to create a firewall to block certain IPs? I'll have an nginx server in front of apache. How have others implemented these features? Is there anything else I should be thinking about? I don't mind a command line interface.

Then in the task:
class processTask(Task):
def run(self, modelName, pk):

Forcing group_by on a field other than id
I'm trying to do a query that needs a group_by on a field other than id.
I've tried this:
s=Song.objects.using('bmillham').annotate(Count('played__date_played')).order_by('-played__date_played')
the generated query is:
>>> print s.query
SELECT `song`.`id`, `song`.`file`, `song`.`catalog`, `song`.`album`,
`song`.`album`, `song`.`year`, `song`.`artist`, `song`.`artist`,
`song`.`title`, `song`.`bitrate`, `song`.`rate`, `song`.`mode`,
`song`.`size`, `song`.`time`, `song`.`track`, `song`.`update_time`,
`song`.`addition_time`, COUNT(`played`.`date_played`) AS
`played__date_played__count` FROM `song` LEFT OUTER JOIN `played` ON
(`song`.`id` = `played`.`track_id`) GROUP BY `song`.`id` ORDER BY
`played`.`date_played` DESC
I tried adding
s.query.group_by = [('played', 'date_played')]
but that doesn't change the query.
Am I missing something here, or can't this be done?
Thanks!

Meta class ordering by related field in ManyToMany model?

performance of model instgance save()
Hi, I've been writing a testing to backfill a database (postgres) with a year's history to test the performance and I've been a bit surprised by the length of time it takes to run. I have a simple model that contains only a single datetime value and it seems (based on timing 1000 operations) that creating and saving an instance takes about 100ms, where as running "EXPLAIN ANALYZE" on a corresponding INSERT via psql claims that to take 0.1ms. Does anyone have an idea as to whether that ratio sounds reasonable? If so, is there any way to speed up the saving process?

Re: performance of model instgance save()
Having hauled myself a few feet up out of the abyss of ignorance, I can answer my own question (which might be of benefit to others getting started with django). To clarify the problem, I have a standalone script that imports the django settings and uses its ORM pleasantness to populate one of the model's tables with a history of 2 million entries. My initial version was really slow and eventually ran out of memory. After a little searching I found two useful things: - batch the inserts into transactions - the default behaviour is to commit after each save() and bundling several hundred per transaction seems to speed things up for me by a factor of 7 - switch DEBUG to False in the settings (something I read in the tutorial that wasn't relevant at the time...).

Re: performance of model instgance save()
Sure - it's just that bit more convenient and readable to use the ORM approach. If I get the chance, I must try substituting direct calls to psycopg and see if that makes it significantly faster again. I'd guess there's maybe another factor of 2 to be had. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Common sense is telling me that any further performance gains I get for this test script will be more than offset by the time I've spent on them :-) I switched to using psycopg2 directly to do the inserts (committing in batches of several thousand) and found roughly another factor of 2. For what it's worth, that single sample point is in the same ballpark as the 10x improvement mentioned for dse. One thing that was confusing for a while was that the first batch of inserts takes 5 times as long as subsequent batches. I didn't really get to the bottom of why that might be. It might be fixed by using a server-side cursor (maybe the first batch expands the client-side memory inefficiently, but hangs on to it for subsequent batches), but when I seemed to hit a bug when I tried using a named cursor (psycopg2 2.2.1). And then I climbed back out of the rabbit hole. -- You received this message because you are subscribed to the Google Groups "Django users" group.

I want to convert the class to do its work using multiple threads, but I'm having trouble getting the tests to run against the multi-threaded version. I've tried sqlite3 and postgres as back-ends, but to no avail. Is there a problem where the testing framework uses transactions to rollback any changes from one test to the next and so the evolving state of the database in that transaction is hidden from the other threads? Can the database connection (and hence transaction) be shared between the threads? Has anyone encountered this problem before? (And, ideally, came up with a really neat solution...)

Re: spawning threads within test cases in django test framework
Thanks for the replies. I realised that I could reorganise the code so that all the database updating was done in the main thread. Re TransactionTestCases, I knew I'd read something related to that but didn't find it when I went looking yesterday evening; it sounds like that would have worked in this case. -- You received this message because you are subscribed to the Google Groups "Django users" group.

auth.LoginTest seems to require sites
Hi, When I run the unit tests, I get a failure (stack trace below) from django.contrib.auth.tests.views.LoginTest. test_current_site_in_context_after_login calls Site.objects.get_current() which fails because I'm not using that app. If I include it in the list of installed apps, then the test passes. However, then a bunch of the tests that I've written fail; I think that's because they are using fixtures that are not valid with respect to the schema defined the inclusion of sites, but I haven't confirmed this. The standard apps that I'm using are: 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.admin', Is the test broken or is there something that I'm doing that makes the sites app mandatory?

audit changes to models
Hi, I need to add a basic audit capability to a django app. There seem to be lots of superficially similar apps and modules around: django-audit, django-audit-log, AuditTrail, SimpleHistory. Does anyone have any experience with these or recommendations? The models I need to track are quite simple: A, B, C where A has a many-to-one relationship with B, and B has a many-to-one relationship with C. I'd like to track create/update/delete operations together with the name of the user making the change, and present a table that can be filtered by the name of a C instance, or by the name of the user/editor.

TimeField with minute-resolution in forms
Hi,
I have a form with a TimeField and I'd like it to only accept values
in the form hh:mm, as opposed to hh:mm:ss.
The form is a ModelForm and I've overridden the 'time' field with a
TimeField where I've specified the input_formats as ['%H:%M']. This
works fine when entering value for a new instance of the model, but
when I edit an existing instance, the value that I entered as '12:30'
is rendered as '12:30:00' and so the instance fails to save.
Without much hope of success (and that proved wildly optimistic), I
tried changing the rendering of the form as follows:
{% if field.label == "Time" %}
{{ field | time:"H:i" }}
{% else %}
{{ field }}
{%endif%}
But that didn't work even a little bit.
Do I need to subclass TimeField? Is there a method that controls the
"output_formats"?
Or maybe that's not the way to do it. Could anyone offer any advice?
Thanks in advance,
Brian

Re: TimeField with minute-resolution in forms
Is that not the opposite problem? I enter a value, which is correctly rejected if I specify a non-zero seconds value, but when I try to edit it again, the value in the form's entry-box has been rendered as "hh:mm:00". Surely its the "from_python" method that I need to override - if such a thing exists? Brian -- You received this message because you are subscribed to the Google Groups "Django users" group.

Include Django form in PHP based website
I'm learning Django and was hoping to get some advice on an application I want to try. I'm trying to create a Django form that is included in a php based website. I'm working on a php based website that has a 'contact us' form that was created with http://wufoo.com/. In the php website there is a little code to include the wufoo form. The form is created in wufoo and they manage the e-mails and storing the data. I want to replace the wufoo form with my Django form. My plan was to host the Django form on a new domain. My reason behind wanting to use Django is so that when the contact is submitted I can store the info in a database, send an e-mail, and write the data to another program. I don't care about wufoo's automatic form building; My plan is to hand write the form code. I bought the book 'The Definitive Guide to Django: Web Development Done Right' and I've read about half of it. It seems creating the form is really easy but I'm not sure the best way to include that form in the php website. Do you have any suggestions about creating a Django form that will be included in a php website? In the php website, I'd prefer not to use javascript.

Re: TimeField with minute-resolution in forms
Just in case anyone else has the same problem and finds their way here...
The answers were there in the documentation once I rooted around for a
while. I just need to override the default form field provided for my time
model field and explicitly specify the allowed formats.
class EntryForm(ModelForm):
time = TimeField(required=True,
error_messages = {'invalid' :
"Please enter a time of the form
HH:MM"},
widget=TimeInput(format='%H:%M'),
input_formats=['%H:%M'])

same form model with separate admins and data
I've created a form with Model->ModelForm flow. Django is running on a sub-domain and I'm putting separate instances of the form on multiple php websites via iframe. How can I use the same form model but have independent forms? For example I want: form1 to be at: example.com/form1 form2 to be at: example.com/form2 form1 admin to be at: example.com/form1Admin form2 admin to be at: example.com/form2Admin I want form1 and form2 to use the same model but act independent of each other. For example I want form1 data to only be present in form1Admin. I believe I can add options in the url.py file for the different forms but I'm not sure how specify keeping the data separate in the database and setup the admin page. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: same form model with separate admins and data
Hi Michal, Can you provide details about the QuerySets part? I'm new to Django. One of the ideas I had was using inheritance. For example: --- myBaseModel(models.Model) … class form1( myBaseModel ): pass --- The problem I'm seeing is that when I use form1 the data gets put in form1 and myBaseModel.

Re: same form model with separate admins and data
Hi Landy, You understand the problem correctly. I'm not sure how to implement your suggestion. I'm seeing a when I do similar to the following: - class myModel(models.Model): first_name = models.CharField( max_length=100, verbose_name='first') class abstractForm( ModelForm ): class Meta: model = myModel class myForm(abstractForm): class Meta(myForm.Meta): model.table_name = 'test_model' - Also, would db sync work with this approach or would I have to manually add the table?

Re: same form model with separate admins and data
I've figured a way that I think will work best for me for the model
and form but I'm having trouble with writing the view. Here is my
pseudo code
models.py
-
class baseModel(models.Model):
first_name = models.CharField( max_length=100,
verbose_name='first')
class form1Model( baseModel):
pass
class form2Model( baseModel):
pass
-
forms.py
-
class baseForm(ModelForm):
class form1( baseForm ):
class Meta(baseForm.Meta):
model = models.form1Model
class form2( baseForm ):
class Meta(baseForm.Meta):
model = models.form2Model
-
view.py
-
def form1View(request):
if request.method == 'POST':
form = form1(request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect('/thanksForm1/')
else:
form = form1()
return render_to_response('form_template.html', {'form': form} )
-
I'm not sure how to create a view that can be reused. The only
difference is the form name and the 'thank you' page. I thought about
a Decorators but it doesn't seem like that is the right tool to use.

inherit adminSite and get 404 when click model
I have multiple models. I'm trying to create an admin site for all
models (using admin.site) and an admin site for each model (by
inheriting from AdminSite).
The admin.site is working as expected. The AdminSite will load the
app as normal but when I click on the model, I get a 404 error.
I'm following very closely 'How to have 2 different admin sites in a
Django project'(http://stackoverflow.com/questions/3206856/how-to-
have-2-different-admin-sites-in-a-django-project).
Here is the pseudo code of what I'm doing:
model.py
---
class myBaseModel(models.Model):
first_name = models.CharField( max_length=100)
class myModel1( myBaseModel ):
class Meta(myBaseModel .Meta):
verbose_name = 'my model 1 info'
class myModel2( myBaseModel ):
class Meta(myBaseModel .Meta):
verbose_name = 'my model 2 info'
---
admin.py
---
admin.site.register( myModel1)
admin.site.register(myModel2)
---
myModel1Admin.py
---
class myModel1Site(AdminSite):
pass
adminModel1 = myModel1Site()
adminModel1.register( myModel1 )
---
url.py
---
from django.contrib import admin
admin.autodiscover()
from .myModel1Admin import adminModel1
urlpatterns = patterns('',
url(r'^masterAdmin/', include(admin.site.urls)),
url(r'^model1Admin/$', include(adminModel1.urls)),
)
---
The url is working as expected. When I go to
the page looks as I would expect but when I click on
'my model 1 info' I get a 404 error.

Customize Admin Advice
I'm hoping to get advice about customizing the admin. I have a series of filters I need to run and then I want the ability to loop though this list. I'm thinking of starting with a form where I can select the filter options. I want a next/previous buttons when I'm looping. How would I implement this? I'm just looking for high level advice. I know I can set index_template in AdminSite to create the first page. I know there is the SimpleListFilter but I don't think I can use it since I want multiple filters that need to be configured. Also I don't want to have to select all the models to loop though them. I plan on writing a custom add/change view. I'm not sure how to go from the selected filter options to looping though each of the selected models. I'm not sure if I can pass and store a query set for when I loop though each model. Some of the options I've thought about is storing the filter parameters in the url and the current model number. Another thing I thought about is storing the results in database and recalling it.

I take it you mean the flat pages part of step 3? I am using TinyMCE
for admin text areas, and it works great. I've never tried it with
flat pages yet. But the reason you have to do that unregister and
register step (for flat pages only), is that because flat pages are a
contributed app, and existing code is already registering a model
admin class for it. If you want to use TinyMCE for flat pages, you
have to create your own model admin for it with the appropriate media
class, undo what the flat pages app already did by unregistering it,
then replacing it with your own.
You don't have to do all that unregister/register stuff for the models
you write.

Re: Test failures with SQLite :memory: database - contenttypes, auth and sites
Hi Chris, I just ran into this same issue. I eventually figured out that adding TEST_DATABASE_NAME to settings.py (to prevent Django from using the default memory database for sqlite) works around the issue. As far as debugging the memory database problem, I was getting the "IntegrityError: django_content_type.name may not be NULL" error. I traced this down to this line: emit_post_sync_signal(models.get_models(), verbosity, interactive) in /django/core/management/commands/flush.py If I comment out that line, the error does not arise. -Brian On Oct 25, 9:50 am, "Chris H." <[EMAIL PROTECTED]> wrote: > I've noticed at work and with my personal code that since the upgrade > to Django 1.0 that I'm getting test failures when I run the unit tests > under a SQLite :memory: database. > > I thought it might be something to do with those two codebases, so > this morning I started a fresh project and I'm seeing the same > problem. > > Is anyone else seeing this... the steps I took to reproduce were: > 1. django-admin startproject sqlitetest > 2.
