*now* I understand. I replaced 

from django.utils import unittest
with
from django.test import TestCase

and all is well. I think the dev docs need to be clearer on this point
and mention this at the outset. After all they *are* dev docs.

The problem here is that assertContains is not part of unittest/unittest2.

It's defined in TransactionTestCase in django.test, which extends 
unittest2.TestCase and adds in assertContains, assertNotContains, 
assetFormError, basically django specific assertions.

I am using 2.6, but according to the django docs, django has a bundled
version of unittest2 which is accessed from django.utils.unittest which
is meant for python <2.7.

I should also add, TransactionTestCase is the base for TestCase and TestCase 
is really a patch to convince TransactionTestCase that a transaction occured, 
but the transaction does nothing.

TestCase's docstring:

"Does basically the same as TransactionTestCase, but surrounds every test with 
a transaction, monkey-patches the real transaction management routines to do 
nothing, and rollsback the test transaction at the end of the test. You have 
to use TransactionTestCase, if you need transaction management inside a test."

from django.test import TestCase

the stuff in utils.unittest is unittest2 stuff if you're using python <2.7 
(unittest2 is part of 2.7 now as unittest).

assertContains is a django specific test and located in test.TestCase with the 
others (you can find TransactionTestCase in there also).

see if your home directory has an 'x' permission at the end:

and that all the directories that you are accessing under it also have

file upload size problem

[vamsy krishna]

Hi,

I'm doing a file upload from one of my forms and writing the content
to a temp file on the server. The problem is any file of size more
than 250 KB is throwing the below error:

Request Entity Too Large
The requested resource
/tera/tera_upload/
does not allow request data with POST requests, or the amount of data
provided in the request exceeds the capacity limit.

I read through the django file uploads documentation and it says the
default file upload size in memory is about 2.5 MB. Can anyone tell me
what I'm overlooking? Also how do I set a maximum file size limit and
handle it?

Thanks,
Vamsy

Re: How to limit a ManyToManyField to three choices?

[greenie2600]

werefr0g—

Yep, that's actually the solution I'm looking into right now. However,
I'm getting an error when trying to save a new instance of the
Restaurant model:

"'Restaurant' instance needs to have a primary key value before a many-
to-many relationship can be used."

Here's the new code that's triggering this error:


from django.db import models
from django.contrib.auth.models import User
from django.core.exceptions import ValidationError

class Restaurant( models.Model ):

user = models.ForeignKey( User )
name = models.CharField( max_length = 128 )
slug = models.CharField( max_length = 24, unique = True )
cuisines = models.ManyToManyField( 'Cuisine', help_text = 'Choose
up to three' )

def __unicode__(self):
return self.name

def clean( self ):
raise ValidationError( type( self.cuisines ).__name__ )

class Cuisine( models.Model ):
name = models.CharField( max_length = 32 )
def __unicode__(self):
return self.name
class Meta:
ordering = ['name']


As you can see, my custom clean() method simply raises an error
containing the type of the cuisines property. And even this is enough
to trigger the error shown above. Doing len( self.cuisines ) gives the
same result. (Raising an error containing a literal string, without
attempting to inspect the cuisines property, works as expected.)

Any ideas? It really seems like it should be possible to perform this
check at the model level. (bagheera, I'll resort to form-level
validation if I have to—but only if I have to. Client-side checks are
for UI convenience only, which is a peripheral issue.)

I'm new to Django and Python, and at this point I'm more interested in
learning the Right Way to do this (if there is one), or *why* I can't
do it at the model level (if, in fact, I can't).

Authentication Using django.contrib.auth.middleware.AuthenticationMiddleware

[hank23]

I'm trying to use the the built-in authentication framework/middlework
but so far haven't figured out how to use it correctly. I'm just
starting a new project with this and I have placed the
"@login_required" decorator in front of my first view and want to
force the user to login at this time. I have coded the
"settings.LOGIN_URL" with a value of "/admin/" and this forces the
user to the admin screen, but doesn't redirect after that point it
does not redirect, though the new url that is displayed in the browser
window's address field shows the correct original url but appended
after the "/admin/" portion of the request like this:

/admin/?next=/mymedia/

It just stays on the successfull login/admin screen. What am I
missing? I would appreciate any help I can get on this. Thanks.

I don't believe so, per this thread:

Sounds like it will work OK with default Python 2.6, it's just (oddly)
packaged to also require/pull down Python 3.1.

How do I run test and get results programmatically? (django, south, fixtures, sqlite)

[Jumpfroggy]

I have an app that I'm starting to write tests for.  The app uses
south for all migrations and mysql for the db.

I wrote some tests and also created an initial_data.json fixture to
provide some default data.  If I run "python manage.py test", the
database is created via sqlite, the tests are run, and then the report
is spit out.  This works fine.

However, I want to automate this where I can programmatically run
tests, find the failures, and do some custom logging/saving of the
failures.  How do I run the tests in python?

I've tried a few variations of the below code, but the problem is the
database.  When I run the "python manage.py test" command, it
automatically uses sqlite3 as the backend, creates the database, and
uses it for all tests.  However, when I run my own tests, it uses the
mysql backend.  If I force it to use sqlite, is has problems with the
fixtures because the migrations are not run before installing the
fixtures.

How do I run tests manually using the same database setup that happens
when using the manage.py test command?

My code:

import my_application.settings

# NOTE: Use this to force the testing database to use the sqlite
engine.
my_application.settings.DATABASE_ENGINE = 'sqlite3'

from django.core.management import setup_environ
setup_environ(my_application.settings)

from django.conf import settings
from django.test.utils import get_runner

verbosity = 1
interactive = False
failfast = True
TestRunner = get_runner(settings)

test_labels = ()

test_runner = TestRunner(verbosity=verbosity,
interactive=interactive, failfast=failfast)
failures = test_runner.run_tests(test_labels)

And this is the error I get:

calling TestRunner.run_tests()
  verbosity: 1
  interactive: False
  failfast: True
  test_labels: ()

I didn't try  it, but werefr0g may be right. It seems that
Model.clean() is the method do you need. And you can still add a

Hello,

Can Model.clean() method help you? [1] You'll still have to pay 
attention to validation before trying to save your instances.[2]

I had seen the limit_choices_to parameter, but I thought it controlled
*which* choices are available to the user - not *how many* they're
allowed to choose.

I want to show the user a list of 20 or 30 cuisines, but forbid them
from checking more than three.

Can you show me an example of how I'd use limit_choices_to to limit
the *number* of choices the user can select?



Form validation.

this should work

class RestaurantForm(forms.ModelForm):
 cuisines = forms.ModelMultipleChoiceField(Sklep)

 class Meta:
 model = Restaurant
 def clean_sklepy(self):
 cuisines_clean = self.cleaned_data[cuisines]
 if len(cuisines_clean) > 3:
 raise forms.ValidationError('You can't choose more than  
three items!')

 return cuisines_clean





Sorry, i left some of my code :P But u got the idea.

or u can add a js script to this form field that will disallow selecting  
more than three items instead validating model (or do both).

Thanks.

However, I tried the sample code in your link, and I don't think it
will work. Returning a string from the overridden save() method
prevents the record from being saved to the database, but by the time
the save() method is invoked, my ModelForm (and consequently, I
presume, the underlying Model) has already been tested as valid. The
Restaurant isn't saved, but the form isn't redisplayed and no error
message is shown, and code execution proceeds as if the form were
valid (because it *is* valid; it just wasn't saved).

I think I need to override the model validation instead. Perhaps I
need to override Model.clean_fields()?



Right, i just get to that point, there is a cave rat about limiting  
choices on form level.

Depending on limiting query it may make problems if you edit this object.

afik U can't validate m2m fields on model level, but u can do it on form  
level and rise forms.ValidationError if needed in clean_field().

Hi all -

I have two models with a many-to-many relationship: Restaurant and
Cuisine. The Cuisine table contains, e.g., "Italian", "Mexican",
"Chinese", etc. Each Restaurant record can be associated with one or
more Cuisines.

Here's the thing: I'd like to limit this to three Cuisines per
Restaurant. So when editing the record for "Bob's Pan-Asian Buffet",
the user would be able to check "Japanese", "Chinese", and "Korean",
but wouldn't be able to check a fourth box.

My question: can this be enforced within the model, or is this
something I'd have to build into my interface layer?




You can limit choices on model level:

http://docs.djangoproject.com/en/1.2/ref/models/fields/#django.db.models.ForeignKey.limit_choices_to

If query is too complicated (cuz u want to access object's data, witch  
isn't yet available), you still can limit choices on form level, by  
overriding __init__



class RestaurantForm(forms.ModelForm):
cuisines = forms.ModelMultipleChoiceField(Sklep)

class Meta:
model = Restaurant

def __init__(self, *args, **kwargs):
super(RestaurantForm, self).__init__(*args, **kwargs)
self.fields[cuisines].queryset =  
Cuisine.objects.filter(pk__in=[fancy query])

Re: How to limit a ManyToManyField to three choices?

[gontran]

Hi greenie,

you just need to override the save method from your model Restaurant.
Before saving each instance, you check if the restaurant already  has
3 Cuisine's objects associated. If yes, you don't save the instance
and raise an error for exemple, if no, just call the standard method
of the super class Model.
You will find more infos in the django documentation:
http://docs.djangoproject.com/en/dev/topics/db/models/#overriding-predefined-model-methods

How to have user defined fields

How can I have  "user defined fields" ( not field types).

So user will define some custom fields (with standard types) and it
will be shown and available to all members of his group on screens and

When you define an abstract model, you have to define the ``abstract''
property inside its Meta.
http://docs.djangoproject.com/en/1.2/ref/models/options/#abstract
http://docs.djangoproject.com/en/1.2/topics/db/models/#abstract-base-classes

That way your abstract class can inherit models.Model and will have no
database table created.

Are you sure that the condition is true - that the form is valid? Put some

django frontend to openmesh radius

[yolabingo]

I put a simple Django site (using only admin so far) in front of a
MySQL DB used as a backend by a freeradius server.

For each radius user, I need to update the 'radcheck' table, which
contains one or more attributes for each user.

+---+--
| Field| Type
+---+--
| id | int(11) unsigned
| username  | varchar(64)
| attribute  | varchar(32)
| op| char(2)
| value   | varchar(253)
+---+-

So, a user might have values like:
+--+-+---+
| username | attribute  | value
+--+-+---+
| joe | User-Password | mysappword
| joe | Session-Timeout  | 24000

and so on.

I'm thinking I can use inheritance in some manner, but not sure how to
have changes to `username` to cascade to all of these entries.  I am
not particular about how this happens (I believe it can be done using
'save_to()' for each model), but am curious if there is a more elegant
way to do this via model definitions.

Thanks in advance,
Todd

cache and anonymous only

[plungerman]

greetings,

we are using django trunk, updated from time to time.  we were using
revision 13303, and then wanted to update to the current revision
(15776 at the time). upon updating to 15776, the caching behaviour of
our apps changed. we are using CACHE_MIDDLEWARE_ANONYMOUS_ONLY = True
and authenticated users will need different content served up at the
template level for any given view. for example, they will see icons
for editing content, a "dashboard" bar for administrative purposes,
etc. anonymous visitors will see the same content, without all of the
administrative features.

at 13303, this was not a problem.  at 15776, it appears as though the
CACHE_MIDDLEWARE_ANONYMOUS_ONLY flag is not working properly.  an
anonymous user will go to a view, that page will be cached, and then
an authenticated user will visit the same page and see the "anonymous"
version. and vice versa, which is a problem since anonymous users will
then see a page with administrative content.  by using django
authority, we prevent any anonymous users from doing anything
administrative, but it's still a problem from a UI perspective.

NOTE: we are not using the cache middleware. we are using cache_page
decorator for our views.  should we be using the middleware in
conjunction with cache_page?

basically, with CACHE_MIDDLEWARE_ANONYMOUS_ONLY set to True,
authenticated users should be served up content dynamically, built at
request time. anonymous users should see cached content, if available,
and if not, the page is built dynamically at request time, and then
cached for subsequent anonymous requests.

i am aware of ticket #15260

http://code.djangoproject.com/ticket/15260

and it seems to have been closed, but we are still experiencing issues
with caching.

any thoughts?

thanks in advance.

caching static/domain tables

[Cesar Devera]

I have in my models, some tables that hold static information, like
status codes, types and descriptions, for example:

in models.py:

class CustomerStatus(models.Model):
name = models.CharField()

class CustomerType(models.Model):
name = models.CharField()

class Customer(models.Model):
name = models.CharField()
type = models.ForeignKey(CustomerType)
status = models.ForeignKey(CustomerStatus)

so, we may have statuses like 'active', 'inactive', 'blocked',
'waiting', 'whatever',
and types like 'small', 'medium', 'other'
this statuses and types will *never* ever change.

and I use them in the templates to show select inputs, so my pre-form
view is like:

def newCustomer(request):
customer = Customer()
statuses = CustomerStatus.objects.all()
types = CustomerTypes.objects.all()
c = locals()
c.update(csrf(request))
return render_to_response('customer/customerform.html', c)

oka, okay, I could use a ModelForm on Customer, but for sake of the
example, let's consider the code above. (albeit I think the final
effect would be the same)

so, in every request, Django hits the database twice, to get the types
and statuses. but I know that they will never change. so, I'm
wondering about caching the results of those hits.

but I if query them explicitly, Django will still hit the database in
every other access to that tables.

so I thought  I could use a custom manager ou something to override
the get_query_set method and check the cache before going to the
database.

this way, even if Django queries those tables by key, or by any other
way, the results would be cached on every second try.

but I don't want to install any awesome caching solution for my app,
and cache everything and have to worry about expiring caches and all
those side-effects. I just want a simple spartan solution, to cache
forever those kind of tables. I would probably mark them somehow, or
by creating a new attribute like cache=True, or by injecting a new
manager, or extending some class and adding mixings... I'm no sure.

here is the point: what is the best point to do this? use a new
manager and intercept the get_query_set method, and return a custom
cachedQuerySet? and if this is the better way, is there any snippet
explaining how to extend the QuerySet class (which methods are
mandatory to override, etc)? it seems a little complex to mess with
without proper skills...

any other suggestion?

thanks in advance,

Cesar

How to limit a ManyToManyField to three choices?

[greenie2600]

Hi all -

I have two models with a many-to-many relationship: Restaurant and
Cuisine. The Cuisine table contains, e.g., "Italian", "Mexican",
"Chinese", etc. Each Restaurant record can be associated with one or
more Cuisines.

Here's the thing: I'd like to limit this to three Cuisines per
Restaurant. So when editing the record for "Bob's Pan-Asian Buffet",
the user would be able to check "Japanese", "Chinese", and "Korean",
but wouldn't be able to check a fourth box.

My question: can this be enforced within the model, or is this
something I'd have to build into my interface layer?

Here's my models.py.

from django.db import models
from django.contrib.auth.models import User

class Restaurant( models.Model ):

user = models.ForeignKey( User )
name = models.CharField( max_length = 128 )
slug = models.CharField( max_length = 24, unique = True )
cuisines = models.ManyToManyField( 'Cuisine' )

def __unicode__(self):
return self.name

class Cuisine( models.Model ):

name = models.CharField( max_length = 32 )

def __unicode__(self):
return self.name

class Meta:
ordering = ['name']

Chaining stacked inline

[gontran]

Hi,

I'm wondering if it's possible to chain StackedInlined object in a
django admin page.
Let me explain it:
I have a class UserProfile which is linked by a OneToOneField to the
django auth module class User. By this way (which is recommended) I
store additionnal informations about my users. In those informations,
I have a ForeignKey to the school of the user.
With a StackedInline class, I can edit user's profile in a user admin
page but I also want to be able to edit the school of a inside this
page, not with a pop-up.

Is it possible to achieve this?

Just to sum-up:

My model:
Class UserProfile(models.Model):
user  = models.OneToOneField(User)
 extra fields
school = models.ForeignKey(School)

My admin.py:
admin.site.unregister(User)

class UserProfileInline(admin.StackedInline):

model = UserProfile

class UserProfileAdmin(UserAdmin):

inlines = [UserProfileInline]

admin.site.register(User, UserProfileAdmin)




Thank you for your help

Exactly, I use a pip requirements file, and if its an app that I'm
working on, it gets installed from svn. Eg:

-e svn+https://svn.nubtek.com/libraries/python/rc/trunk#egg=rc

this gets installed to venv_dir/src/rc, which is then a full svn
checkout, which I can manually switch branches, merge/test etc. When I
want to make it permanent, I can simply update my requirements.pip,
blow away my venv dir and reinstall (or remember the full invocation
for pip install --upgrade -e etc).

Cheers

Tom

One possibility is to use a development egg with is a revision control
checkout.  (The whole distutils/setuptools/distribute thing seems to be
specifically aware of subversion at some level, offering to use revision
information in version numbers.  I haven't noticed support for other
VCSs, but there could be ways to use them by having script wrappers
on your shell path...).  Then you can simply update to another revision
to test with it.

In this case, I'm sorry, I'm not sure. I don't use pip, given the arguments 
I've seen for it, I've never had a reason to really investigate it myself. 
Setuputils/distribute/easy_install are 'good enough' for me.  A long time ago 
james bennet posted a big why you want to use pip on this list, I can't 
remember much more about it, but you might want to search for that posting.

I do things manually with checkouts. If I want to work on a branch, this is 
checked out to a new location (since it's a radical change/fork of a project), 
i.e. same lib dir, different package name to let me know it's a branch. Tags 
are there for historical reasons, really I just use them to mark completion 
points and they are considered part of the main tree (usually). It's just 
easier to know how far back to go when searching for a revision that 
introduced a bug (usually). Or if I completely messed up the current branch, I 
can just go get the last tag. 



Mike.

Re: Packaging and development workflow for decoupled apps.

[DaleB]

I guess i wasn't clear enough. I am not so much concerned with when to
use tags and when to use branches.
I am still looking for a smooth development workflow.
I created a libs-dir which i put on my python path an put my different
apps in it.
Okay, now i can refer to my apps from any project without copying the
files. Great and a lot better than before.

So now i start to create different branches for an app, i create a
development branch an change stuff.
As the app is on my path my projects initially refer to the state/
branch of an app that ist currently checked out, right?
That's what i refered to by "switching branches" (= changing the
branch of my app in my libs-dir)

Another (better?) idea i had looking at pip's docs was to take my libs-
dir off the python path, put them in a git-repo and use pip to install
my app.
Pip's option to refer to certain tags and branches (http://
pip.openplans.org/requirement-format.html#version-control) seems
pretty ideal in this situation.
The only drawback i see is that i have to install and uninstall quite
often if i want to test different branches/states of my app in a
project.

And now i am not sure which route is more promising or if there's even
an easier way i don't regard at the moment.
Hope that's more clear.

Thanks fpr you patience,
Andreas

This is more of a policy situation. What that means is that it can be 
different. Depends on how you use them.

Tags, usually mark a completion point (or milestone). 

Branches are usually a fork or a radical change or a fork..

In django's history, when they added unicode support through out it, they had 
the main branch with work being aimed at generally improving django.

The unicode branch was were all the changes for adding unicode was done. We as 
users of django had our choice on what to use, checking out the main tree or 
the branch with the unicode system.

Personally,. I check out branches to a different location than the main 
project as I consider them different applications. 

Tags, I just use to mark important milestones for the code I'm working on.

Django models and inheritance

[Mark J. Nenadov]

Hello folks,

I'm a long time Python developer that is new to Django.  I have a few
questions about the role of inheritance in the models for an app.

As I build my models, I'm finding at least somewhat of a need to start
doing some inheritance, and if not a need--at least a design-related
desire to do it Everything seems to work nicely and neatly in theory
if I stick with concrete super classes, but if I venture in the area
of abstract super classes, things seem to get messy.

If I have my abstract super classes inherit models.Model,  things
technically can work. However, I arrive with a rather overly complex
SQL design generated from them (like needless tables for abstract
super classes).

On the other hand, if I have my abstract super classes NOT inherit
models.Model and then use multiple inheritance on my subclasses (ie.
have the subclasses inherit both models.Model and their Super class),
then I end up with non-functional SQL tables (ie. the SQL table for a
model would not contain critical fields that in the model had been
inherited from their super class).

Am I missing something? Is there a way to have my models include
properties inherited from an abstract super class into the SQL it
generates? And ideally without creating tables for each abstract super
class? Or is this just too much in the way of complex OO for
models.py, and maybe I'm just over-doing it and  an experienced Django
developer will point out the futility of what I'm trying.

In any case, I don't want to give up a abstract super classes until
I've satisfied myself that there is no way to accomplish this.

Any help that can be offered is much appreciated!

Thanks,
~Mark

Re: Django app and Amazon AWS (beginner)

[Graham Dumpleton]

One can if you want to get a development system closer to production use 
Apache/mod_wsgi in such a way that automatic code reloading on any change 
works, just like Django development server. See:

  http://blog.dscpl.com.au/2008/12/using-modwsgi-when-developing-django.html
  http://blog.dscpl.com.au/2009/02/source-code-reloading-with-modwsgi-on.html

Using that approach means you can properly test multithread and multiprocess 
configurations.

Also, if you have only been looking at mod_wsgi integration notes on the 
Django site, ensure that you also read what is on the official mod_wsgi 
site. Also ensure you try and get a hello world WSGI program going before 
you try to do Django itself. That can avoid a lot of problems and 
misunderstands when it comes to setting up Django. See:

  http://code.google.com/p/modwsgi/wiki/IntegrationWithDjango
  http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide

[Graham Dumpleton]

Go watch:

http://code.google.com/p/modwsgi/wiki/WhereToGetHelp?tm=6#Conference_Presentations

That presentation explains a lot about permissions and other errors you can.

Recommend that before you even try and get Django running that you get a 
WSGI hello world script running. Use what is shown in:

Re: What is it with Django and 2008?

[Artem]

I guess it's because of Django v1.0 release - people started to
consider it like stable production-safe framework. So most of Django
books came out after that, though most of them have few revisions to
be up to date, but in searches first revision usually most noticeable.

Re: When do we stop using Django admin?

[Dan Gentry]

I tend to use the Admin for internal tasks - ones that would be
performed by a application or system administrator.  These are people
that understand the data structure and know things like the effects of
a cascaded delete.

For users, even a customer 'admin' person, I would write my own views
that will handle additional conditions rather than asking that user to
make the decision.

[Jirka Vejrazka]

OK - I'm going to ask the obvious question here - have you made sure
that Apache web server user can read ALL your configuration files? The
log reveals that there are permission problems on .htaccess file that
is stored in your home directory (where Apache can't reach by
default). I'm going to make a guess that there's where your
WSGI-related Apache configuration is.

Here i need to get sum of votes for each question.So I need to edit
the code in the function getCount(). I try with the above code but

No fixtures found

[Shakthi Kannan]

Hi,

I am just getting started with Django (1.2.5) on Fedora. I would like
to create separate test data files to be loaded to the test database
for each test case for the mysite/ app. I have the following code
snippets (based on the Django tutorial):

=== mysite/polls/tests.py ===

from django.test import TestCase

from polls.models import Poll

class SimpleTestCase(TestCase):
fixtures = ['poll.json',]

=== mysite/polls/models.py ===

from django.db import models

class Poll(models.Model):
question = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')

def __unicode__(self):
return self.question

def show(self):
string = "show"
return string

class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice = models.CharField(max_length=200)
votes = models.IntegerField()

def __unicode__(self):
return self.choice

=== mysite/polls/fixtures/poll.json ===

[
  {
"model": "polls.poll",
"pk": 1,
"fields": {
  "question": "What is your date of birth?",
  "pub_date": "2011-03-08 12:30:45"
}
  }
]

=== Output ===

Destroying test database 'default'...

If I use a file initial_data.json in mysite/polls/fixtures, and
running ./manage.py test polls, it loads the file, even if I specify
'poll.json' in the tests.py file. I have tried using the following in
settings.py to no avail.

  FIXTURE_DIRS = ( '/tmp/mysite/polls/fixtures/', )

What could be missing? If you have a working app/ solution for that
above that I can refer, it will be very helpful, or if you suggest any
other methods to load dynamic test data, please let me know.

Thanks!

request.user.save() doesnt work

[Ndungi Kyalo]

Hi guys. Am using django non-rel on appengine. I am using django's
auth backend for my authentication, since I did not want to have to
force my users to use gmail logins, and appengine models
{google.appengine.ext.db} for the other models. I have a form where I
allow users to edit their email. So :

if settings_form.is_valid() :
user = request.user
user.email = request.POST['email']
user.save()

print request.POST['email']  returns the correct data entered in the
form. But user.save() just doesnt save!
Am I doing it correctly ? Is there something else I shopuld be doing ?

Re: Help with Apache/Nginx combo

[krzysiekpl]

In my opinion you should add alias in nginx.conf for admin media
files. Put this code in server{}

# admin uses admin-media/
# alias works different than root above by dropping admin-
media
location ^~ /media/admin/ {
alias /usr/local/lib/python2.6/dist-packages/django/
contrib/admin/media/;
}

or this code for your static files

location  /static/ {
root  /path/to/project/where/static_folder_is;
expires max;
autoindex off;
}

Actually, you can have apache/mod_wsgi behind a nginx because of static files.

Anyway, without the errors, there's little we can do.
The documentation 
(http://docs.djangoproject.com/en/1.2/howto/deployment/modwsgi/) gives the 
directions. There isn't much to do to get django working with mod_wsgi.

Steps are:
- install apache
- install mod_wsgi
- configure both
- configure your virtual host
- follow the documentation

Regards,
Xavier.

Order of WHERE statements in filter

[galgal]

I want to make a specific odrer of WHERE statements in my query to use 
multicolumn index in database.
But oder in code is not the same as result query:
code:
filter(user=self.user, province=self.province, city=self.city)

Mysql result:
WHERE (`accounts_usercity`.`province_id` = 6 AND 
`accounts_usercity`.`city_id` = 32 AND `accounts_usercity`.`user_id` = 26 )

Help with Apache/Nginx combo

Hi,

I know this topic was discussed a lot, but in every post for this
topic there are diffrent configuration and this stop helping for me.

Long story short : I changed DEBUG = True to False and all static
media are gone, so this is something wrong in web server conf.

#settings.py#

You'll have to provide a bit more informations if you hope to get some
help - like, what "no success" means *exactly*

Now just for the record, chances are your Profile.id is not the same
as User.id so there's probably something wrong with your view.

Also and FWIW, I had the same need (editing user and profile fields in
a same form) in a couple apps, and always ended up writing my own (non-
model) form. ModelForms are quite handy, but it's sometimes easier and
quicker to write a custom form instead.

you do not really need to use their installer. I have set up some sites

Indeed. With my shiny new installation package i totally forgot about
the fact that the package just needs no be on the path,
no matter where the files are actually stored. That really clears
things up for me.

And thanks for for your example Tom.

One last point.
Now, how do i deal best with different versions/branches of my app? Do
you just switch branches while developing or do you use pip in project
env to refer and switch to different tags/branches in your sourcecode.
The first approach feels more dynamic, the latter more 'stable'. In
the end i guess both work, but what do you do?

Greetings,
Andreas
