Very probably an error in settings.py

STATIC_ROOT has to be an absolut path name using '/' and not '\'
characters pointing to a directory, that is empty (collectstatic will
store files there)


STATICFILES_DIRS should point to the directory, where you put your
static files.

As Praveen pointed out.: A dump of settings.py might help

making history

[Mike Dewhirst]

I want to update a history record whenever a particular record changes.

Is it reasonable to call a method from within the save method of a model 
to go off and do the work?


def updatehistory(recordx):
""" if HistoryX doesn't exist, insert it so the RecordX
author can add commentary. Also, add to the story with
changed values from recordx every time RecordX.save() """
pass

class RecordX(models.Model):
... various fields including 'ancestor' ...
def save(self, **kwargs):
super(RecordX, self).save(**kwargs)
updatehistory(self)

class HistoryX(models.Model):
relation = models.OneToOneField(RecordX, to_field='ancestor')
story = models.TextField()


Is there a better way?

Thanks

Mike

Set order from admin

[Isaac]

Hi folks,

I've having trouble to find a clear solution to my problem. All I want 
is to set a relation between 2 classes, and set filter order from admin 
to the rest of queries.


pseudocode:

Class A
has_many B
Class B
foreign_key A

And then, I want to retrieve B objects from a given A instance in the 
same order as introduced (or changed) in admin.


Any clue about some clear mode to implement it in django?

Thanks in advance

Re: How to order "links" in the Admin?

[Andre Lopes]

Hi,

Thanks for the reply.

I use the field "website_position" to control the position of the url,
this is an Integer field.

The model I use is this:

from django.db import models
import datetime

class Directory(models.Model):
  website_name = models.CharField(max_length=200)
  website_url = models.CharField(max_length=200)
  website_position = models.IntegerField()
  pub_date = models.DateTimeField('date published')


Now I will populate the database with data:


website_name | website_url| website_position | pub_date
Google   | http://www.google.com| 1  |
10-08-2011
Yahoo| http://www.yahoo.com | 2  |
10-08-2011
Altavista | http://www.altavista.com  | 3
| 10-08-2011


The output of this will be: Google, Yahoo, Altavista

Another example: (Here I will reorder the links positions)


website_name | website_url| website_position | pub_date
Google   | http://www.google.com| 3  |
10-08-2011
Yahoo| http://www.yahoo.com | 2  |
10-08-2011
Altavista | http://www.altavista.com  | 1
| 10-08-2011


Ant the output will be: Altavista, Yahoo, Google

The thing here is that I control the positions of the links in Django
Admin with integers in the field "website_position". I'd like to know
if Django Admin have a better way to deal with this. There is possible
to control this with arrows to change the position of links, I click
in the up arrow and the link go up... I click in a down arrow and the
link goes down... This is possible in the Django Admin?


Best Regards,

Re: MySQLdb module not found even though it's installed.

[Subhranath Chunder]

You can check with the following:

python manage.py shell

then do the,
import MySQLdb

If this fails then you are probably running on different python
environments.

Re: Set order from admin

[Thomas Orozco]

You can use a single foreign key and store last changed in your B model.

You can then use object_a.b_set.order_by('myTimeStamp')

Keep filtering from change_list in admin in custom page?

[Thomas Weholt]

Is it possible to keep the filtering done in an admin change_list in a
custom page? For instance, I got a app showing photos where you can
filter on camera, width, height, exif-date, iso speed, exposure etc
and the admin makes filtering my data very easy using a custom
AdminModel. My filter shows up on the right side of the page. But I
want to have a custom page for displaying the actual photos using the
same filter set in the change_list page. Is this possible?

Re: Keep filtering from change_list in admin in custom page?

[Subhranath Chunder]

Yes, you can do that. You would have to override the default
change_view_template. And if required, then probably the changelist_view()
too.

You could probably consider using post_save signals and make things a bit

Re: Keep filtering from change_list in admin in custom page?

Hmmm ... Not sure how to do that. You could say I want an alternative
change_list page, but not by overriding or extending the existing
default one.

Do you know of any example or documentation on how to achive this?

Anyway, thanks for your input :-)

Generating urls for a search-engine-like application

[samuele.mattiuzzo]

Hi all, i'm developing a search-engine-like application using django
1.3 and apache-solr as "database"

I'm now stuck with urls handling. Basically, i need to compose urls
with the parameters used to query solr. Fair enough, but i faced a
problem.

Basically, you can filter your results by choosing a country, a city,
or both (example)

My urls may look like this

url(//, search_view),
url(//, search_view),
url(///, search_view)

as you can see, case 1 and case 2 are a trouble: country and city are
both strings, how's the url supposed to know if a link pointed to one
url or another? Should i use named views in templating? What's the
best way i can use them in my case?

my boss told me to use get requests instead of post, so i could
explicit the parameters, but SEO experts said "NO WAY!". i don't like
get method either, but the reason is different :P
i cannot use get_absolute_url from an object because i have no model
objects (because, since now, there were no need... just an user object
used to store some infos, nothing else)

Any hint on how i can do this? Thanks all in advance!

[Sharing] django-custom-auths

[Subhranath Chunder]

I was working on these django applications which simplifies the use of
third-party logins for a django project without breaking any existing code.

My concerns were:
- No existing code breakage.
- Easy integration with django's own authenication system API.

This is a work in progress with perhaps no documentation as of now. So, I've
included an entire django project itself for now, to check on it's working.
Currently, the Facebook authentication system is fully functional (using the
current OAuth2 based Graph API implementation).

If anyone is interested to try it out, you can check
https://github.com/subhranath/django-custom-auths

Any suggestions for improvements are very welcome.

Thanks,
Subhranath Chunder.

Re: Generating urls for a search-engine-like application

[Subhranath Chunder]

If you are planning for reverse URL in your templates, then named URL
pattern is the thing for you.
https://docs.djangoproject.com/en/dev/topics/http/urls/#naming-url-patterns

Else to simply, you might also consider changing the url patterns to
something like:
/country//
/city//
If you have the opportunity to do so.

Re: Keep filtering from change_list in admin in custom page?

[Subhranath Chunder]

You can either override a particular, or give a completely alternative
change_list page.

For your case, overriding seems to be a better option to me
https://docs.djangoproject.com/en/dev/ref/contrib/admin/#overriding-admin-templates

If you are going for new change_list template
https://docs.djangoproject.com/en/dev/ref/contrib/admin/#custom-template-options

custom made.


- So class based *generic* views also sound like they're for generic 
views, not for your own custom views.


The djangoproject.com pages about class based views also only talk about 
generic views, even though they're perfectly usable for your own custom 
views.



Am I wrong in thinking that the word "generic" is just bad PR (or 
unclear documentation)?

You could make it more explicit:

url(/country//, search_view),
url(/city//, search_view),
url(/country///, search_view)

So prefix all country urls with 'country/' and cities likewise.


You could, if you like the "/italy/rome" style of urls more, also make 
an exception just for cities (but *do* place that exception at the top):


url(/city//, search_view),
url(//, search_view),
url(///, search_view)

So only cities are prefixed with "city/" to distinguish them.


And you'd better use named variables, so

/(?P.*)/

instead of

//

(unless you meant that already in your shorthand form, of course).

The view function then can have keyword arguments:

def search_view(request, country=None, city=None)

Re: {django-tables} Caught NameError while rendering: global name 'name' is not defined.

[Kayode Odeyemi]

Thanks.

Here's the views.py

class TransactionReport(tables.ModelTable):
identifier = tables.Column(sortable=False, visible=False)
created = tables.Column(sortable=True, visible=True)

@classmethod
def get_reports_paid(self, object, req):
return TransactionReport(object, order_by=req)

class Meta:
model = Transaction


@login_required
def display_reports(request):
logger = logging.getLogger(__name__)
dataqs = Transaction.objects.filter(paid="TRUE")
req = request.GET.get('sort', 'created')
tx = TransactionReport().get_reports_paid(dataqs, req)

return render_to_response('webapp/reports.html', {'table': tx,
'rows' : tx.rows})


rows is of type TransactionReport.

Re: MySQLdb module not found even though it's installed.

[babak]

Did that and it didn't fail.
But when I run:
python2.6 manage.py syncdb

everything works fine, so problem solved.

Re: {django-tables} Caught NameError while rendering: global name 'name' is not defined.

[Subhranath Chunder]

You seem to have heavily used external django apps like django-pagination
and django-tables.
I haven't used either of them myself, so it'll be difficult for me to follow
your code like this. Maybe, some else with experience on those might be able
to help you better.

I was about to reply with exactly this - if you are using 3rd party
libraries - firstly, you need to tell people you are using them before
asking for help, and secondly, they often won't play that well with
each other.

In this case, looking at the code for django-pagination (as there
appears to be no documentation), the autopaginate tag is expecting to
be passed a queryset, not whatever a django-tables instance is.

Cheers

Tom

Your python mysql library binder is currently installed with the python2.6
instance only, and not with python2.5

You might consider changing the default python link to the python2.6
instance.

Re: making history

[Shawn Milochik]

I do essentially that, using a post_save signal and dumping the
serialized model instance to MongoDB with datestamp, etc.

The relevant part is this (after importing Django's serializers):

 serialized_object = serializers.serialize(
"json",
sender.objects.filter(pk = instance.pk),
ensure_ascii = False,
)

I store them outside of the primary database because it doesn't makes
sense to store audit history where, if your data is corrupted or
tampered with, you audit data could be also.

E ... I do not want to override. To be precise I want a
button/link beside the "Add " in the change_list which,
when clicked, opens a new page, extending the base-admin template,
taking the current filters used in the change_list and displays the
same data in a different layout, using a different template. Perhaps
I'm not understanding what you're saying, but I need the standard
change_list as well as the alternative one.

But thanks for your help. I see you're very active on the list today.
Very good :-)

Re: Is there a way to use a tree control in my template

[Tiago Almeida]

As far as I know, Django does not ship with that by defaut. Try
searching for an app or a snippet on http://djangosnippets.org
It shouldn't be too hard to do.

Best regards

Seriously? Is there something unclear about the instructions in that

Did you try setting STATIC_ROOT and reading the fine documentation
about STATIC_ROOT?

Re: Generating urls for a search-engine-like application

[samuele.mattiuzzo]

Yeah, it was just a shorthand to let you understand my problem, it
wasn't my actual url definition :)

I was considering the option /country/italy/city/milan/job/engineer/,
it wasn't that bat, but i'm risking very long urls if 4-5 parameters
are set...

Well, i don't understand it plenty, since i never spoke with them
directly. Btw, our "seo consultants" said that /london/designer/ is
SEO-OK while ?city=london&job=designer is SEO-BAD. I really don't
think there's much difference between the two, but i cannot discuss
too much with them :)

If /italy/milan/barber is the normal url, by all means use that.

The other scenarios can then get a longer url, like

/city/milan

This makes the city-only scenario distinguishable from something that's 
a county+city combination. That way your regular urls stay nice and 
short. Best of both ways?

You have two options:

you can extract the value in the view, and put it into the context
that is used to render the template.

you can access it using dot notation [1], which is used in templates
(templates are not python, you cannot write python in templates). Eg:
{% url url-name request.GET.page %}

Best solution: calculate that url in your python view code and just pass 
it along in the context.


The generic rule is that most processing should happen in python code, 
not in your template.

Re: Generating urls for a search-engine-like application

[samuele.mattiuzzo]

Yeah, i'll be taking the best out of every hint!
The big problem is that the user has a lot of freedom. If he just
wants to search for "barber" he can and urls will be /barber/
/... Every parameter is optional, they're just bound to an
order, if they're all present... So i don't have a "special" case (as
the city-only) i can deal with easily :(

GeoDjango and pyspatialite

[Sean]

GeoDjango normally looks for libspatialite for Spatialite
functionality.

I want to use, instead, pyspatialite which has the spatialite
functions built into the sqlite3 library.  I changed the reference in
the standard sqlite3 backend base.py to use pyspatialite instead of
pysqlite2/sqlite3.

I tried changing the base.py for the spatialite base.py in contrib.gis
to look for the sqlite3 library but that didn't work. I'm sure it's a
bad idea anyway to have it load the sqlite3 lib again.

Has anyone found a way to get GeoDjango to pyspatialite?

Thanks,

  Sean

django and extjs: works well together?

[Reinout van Rees]

Hi,

Several people in my workplace are looking at extjs now.
http://www.sencha.com/products/extjs/examples/
Basically, a big javascript UI construction kit. To me it feels like a 
desktop app in a browser window.


Question: does anyone have experience (positive or negative) with extjs 
in combination with django? Django can spew out json just fine of 
course, but it'll have to relinquish a lot of control to the browser. 
And it'll be more "spitting out json" than "using templates".

Re: django and extjs: works well together?

[william ratcliff]

We've used it--it's really domain specific, but you can look at
tripleaxis.smallangles.net (please don't crash us :>).   We do the front end
with extjs and the back-end with django.   We have a number of ajax calls
made by extjs and then handled by django.   We're also finishing up a
dataflow project (where we let users create filters through which their data
flows--imagine labview for data...).  That project also involves creating
users, redis, etc. and takes a bit more advantage of django...

One thing to be aware of is that several tutorials on the web for extjs are
a bit dated--the library has been improved to be more modular in version 4,
but as a result, some changes need to be made to existing code--we've also
had a few issues making it play nice with YUI (long story...).

Incidentally, the example website was coded by a high school student over
the course of a 6 week summer internship with us (who had to learn
javascript, django, and python during that time), so I think the learning
curve shouldn't be too steep

Missing POST request with WSGI

[RoyWilliams]

My problem is that POST data is not being copied into the request
object that my Django code is getting, but the problem only happens
with WSGI.

When I fill in the web form with a browser, the POST data comes
through correctly: request.method is POST and the QueryDict has my
parameters. But when I use code (python urllib) to POST the data, it
does not come through: request.method is set to GET and there are no
parameters (QueryDict). I have checked that this client is really
sending a POST request.

I have done this with CSRF switched on and off, and it makes no
difference.

I have found this to be a WSGI problem, because there is another
installation of the same application that uses mod_python, and that
works perfectly.

Re: Installation Problem cant extract tar.gz file

[Andre Terra]

Possible solutions:


1) Try downloading the file again
2) Checkout from the svn repository.
3) Use a different archive manager.


I'd go with options #2, personally.

Re: How to pass url parameters to template url tag

Simple but totally unpractical for most projects, as it requires
making ALL views duplicating this behavior.

Probably the most cost-effective solution - until you have to parse
all your templates when there's any change. As a side note:
1/ you can use the "default" template filter to handle the case when
there's no 'page' key in request.GET
2/ you can use request.REQUEST if you want to work as well with GET
and POST.


Now for the third solution: write your own template tag. Not
necessarily required, but that's often the best solution wrt/
decoupling / flexibility / maintainability / reusability.

Re: same form model with separate admins and data

[brian]

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.

Thank you for your help

Brian

Definitly not the best solution if this has to work for more than
exactly ONE view.

Indeed. But in Django, Python code is not restricted to views, and
another generic rule is that a view should NOT have to deal with
orthogonal concerns - IOW, it should do the very minimal possible
thing and nothing else.  Template code is where the integration
between different (preferably well decoupled) apps happens - it's
really the "glue" layer of your project - so whatever is part of your
project but none of the concern of a specific view should happen. NB :
when I say "template code", this includes template tags and filters,
context processors and eventually middlewares...

Sorry but your question is not quite clear to me. What do you call a
"form" exactly here ??? A Form subclass or a Model subclass ?

(as a side not: the convention in Python is to use StudlyCaps for
class names, and conventions are a *very* important part of Python).

If what you want is to have two or more models inheriting from a same
base model BUT each with a distinct table, you have to make the base
model abstract (cf the model doc).

Re: dull look after install on ubuntu

[Peter Kovgan]

I seriously tried.
you did not get, that I do not see statics of the ADMIN directory,
not of my own creations.
EVEN ADMIN does not work.
So basically, python does not see admin's preinstalled static files.
To be sure: I'm a beginner, I go through my first tutorial.

I ran the same application on windows installation and it worked.
Now on linux it refuses to work.
crossplatform is not a hot django goal, as far as I see.
I edited path to templates - that was all difference that I've done after I
moved to linux.

I'm thinking, that may be my django installation went wrong...
Now I'm going to reinstall everything from scratch.
Thank you for help.

Re: dull look after install on ubuntu

[Peter Kovgan]

I resolved it, setting DEBUG = True, it was False for some reason, and it
worked so on windows.

I have some doubts, that static files should become unavailable when you set
debug=false.

What do you think?

Re: dull look after install on ubuntu

[Peter Kovgan]

Ok, Ok, I've got it, read docs.

"
The static files tools are mostly designed to help with getting static files
successfully deployed into production. This usually means a separate,
dedicated static file server, which is a lot of overhead to mess with when
developing locally. Thus, the staticfiles app ships with a *quick and dirty
helper view* that you can use to serve files locally in development.

"

But why It must be so complex?
Why default admin statics become unavailable, if you use another server and
not that of development: "runner"?

Should it mean, that I must find elsewhere my admin statics, copy-paste them
to some place and poin to this place from settings.py?

OK
I do not like this burden.

The burden is not really a big burden.

Set STATIC_ROOT in config.py  to a directory, which is empty and where
you have write permissions to.


run afterwards ./manage.py  collectstatic


This should collect all static files (also the ones from standard django
modules) into the STATIC_ROOT directory.

If your STATIC_ROOT directory does NOT contain the files that aren't
served, then this is strange.



Just one more question:

Did you also use Django 1.3 on your windows host or was it a different
version???

I've been considering using custom template tag. Yeah, it is standard and
pretty. I guess
this might take me a while to implement.

However, can this concept also be used to pass page objects (e.g model data
passed to a template from a view) from one view to another.

For instance, I have a request model dynamic data saved in a session. I'm
passing this
data to another view and I want it to change based on the value of a url
parameter?

Displaying results in Template in a Table ? What is the proper way ?Any app?

[Adam Zedan]

Hi i wanted to know what do most people here do when they need to show
results in a template which just needs to be displayed in Table.
For example displaying data from a db etc in a template. I did try an app
called django_tables2 but it just seems really simple with respect to
presentation.
I tried loading the CSS version 'paleblue' of that app but it doesnt work ?
if someone has already tried that please do let me know ?? What do people do
in case they need to display data,allow rearrangement of data etc.Are there
any other apps...looking forward to hearing from you folks

on windows it also was 1.3

I collected statics as you said, but it brought also many not static files
Actually all my sources went there.

Well, the first time, yes, possibly. But that's not rocket science
neither, and that's something anyone whishing to make proper use of
Django should learn.

> However, can this concept also be used to pass page objects (e.g model data
> passed to a template from a view) from one view to another.

You don't pass anything from "one view to another". You eventually
pass data from a request to another, using either request params
(querystring, post...), cookies, or sessions (and of course the parts
of your urls that become view args).

> For instance, I have a request model dynamic data

Sorry, but I don't know what a "request model dynamic data" is
supposed to be. Care to explain more clearly ?

Re: same form model with separate admins and data

[Landy Chapman]

If I understand you correctly, your situation is:

FORM 1  --> [table 1]
FORM 2  --> [table 2]

where FORM1 and FORM2 are *identical*,
and TABLE1 and TABLE2 are *identical*  (same structure)

*identical* meaning definition is the same but names are different for
obvious reasons...


If I understand you correctly I can help you with this.  In other
words Bruno's suggestion above fits perfectly, and you just override
the table_name parameters in the child classes.

Re: Displaying results in Template in a Table ? What is the proper way ?Any app?

[David]

I'm a fan of django_tables2. You have to write the CSS yourself if you
want anything special, but I'm ok with that. It does a good job of
handling server side pagination and sorting as well as custom column
renderers. It also ties in pretty well with Django models if you need
that kind of thing.

I store them outside of the primary database because it doesn't makes

I really like that approach for audit. Depending on where you sent the 
output it would be perfect for defeating the uglies. I have read about 
MongoDB and it looks very interesting.


Although what I'm looking for is audit history in a sense, the history 
is part of the workflow. That means it needs to be inside the database.


If I want to include details of record changes when a document record is 
saved it seems I should look more closely at post_save signals - at 
least to reduce complexity in the models.

Re: making history

[Shawn Milochik]

Mike,

I'm doing something similar in another project. I created a sublass of
models.Model and am using that throughout the project, which makes it
much easier.

On the post-save of any subclass of my custom model, I serialize the
model's fields as a JSON object and store it in a text field of my
application's database in a special audit model. That audit object
stores the timestamp, instance's primary key, and optionally the User
instance that changed it.

There's also a 'description' field in my audit model. For every entry
in the audit table for the same primary key you can grab the JSON and
compare them and write plain text to the description field like 'last
name changed from Smith to Smithe by someguy at 2011-08-10 13:42.'

The beauty of the 'description' field is that if I ever want to change
the format of that, I can change my code and then re-generate the
description from the JSON, so there won't be a cutoff between
"old-style audit history" and "new-style audit history."

Incidentally, my custom model (and therefore all subclasses of it) are
using a UUID as a primary key to avoid the horror that is generic
foreign keys. Just in case you were wondering how my audit scheme
works across various models.

Hi, I'm posting here to announce the release of the Fabfile that I use
for Django projects. Using it, you can make your Django project live
with a single command. It also comes with a default project layout
that I like to start from.

Get the code at https://github.com/reverie/django-fabfile, and read my
perspective on the project at http://andrewbadr.com/log/9/django-fabfile/.

I'm sub-classing models.Model to include created, updated and updated_by 
fields which is pretty ordinary but nice. I'm also borrowing Marty 
Alchin's (Pro Django pp257 - 260) CurrentUserField to automatically 
insert the current user into updated_by.


I used the same technique to subclass models.ForeignKey('Document', 
to_field='ancestor' ..) so I can just add AncestorKey() to any model 
which needs to link to the "line" of documents rather than a single 
document. The project isn't anywhere near finished - I'm still writing 
the models - so I don't know how well all this will work - but my thanks 
to Marty anyway!


Also - I just googled and found - 
https://bitbucket.org/q/django-simple-history/overview which builds on 
Marty Alchin's approach to history. I haven't fully understood his 
approach yet so the content of that link is probably a bit beyond me at 
the moment.

I'm definitely going to rethink my design. You are making me think a 
generic solution is worthwhile.
