Raising a ValidationError in clean() when blank=True and the field is

1. The error appears at the top of the page instead of just above the

2. I can only get one error at a time.

Any suggestions?

Your admin.py file should have this code :
-
from mysite.polls.models import Poll
from django.contrib import admin
from mysite.polls.models import Choice


class ChoiceInline(admin.TabularInline):
model = Choice
extra = 3

class PollAdmin(admin.ModelAdmin):

admin.site.register(Poll, PollAdmin)

According to me, he need not to assign cd, because it is then not used

Re: Help me choose OS for django server

2012-11-01 Thread Nikolas Stevenson-Molnar 
Whatever gives you separate physical resources. The idea is to prevent your app 
and static content delivery from interfering (i.e., consuming CPU, memory, 
bandwidth) with each other. The cheapest and most effective way to accomplish 
this is using a CDN or something like Amazon's S3. For relatively light usage, 
it will only cost you a few dollars a month, and you don't need to worry about 
setting up and maintaining a separate server yourself.

I think you are saying you don't understand my response? I'm asking if the
problem is fixed by replacing formset.save() - with cd.save(), since you
have cd = formset.cleaned_data but no other instances of cd, making it
kinda useless?

should here be a cd = ObjectName() in there?

Tom thank you for helping me on my way in to Django!

I uncomment: 
INSTALLED_APPS = (
'django.contrib.auth',

and with 
$ python manage.py syncdb 

I still get the eror:
 Error: One or more models did not validate: admin.logentry: 'user' has 
a  relation with model , which 
has either not been installed or is abstract. 

But than I also uncommented:

'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',

And everything started to work.

Re: Using RequireJS with Django

2012-11-01 Thread David Hall 
I realise that this is an old topic, but I hope this is useful to other 
people looking to use RequireJS with Django.

You should take a look at django-require, which takes care of integrating 
the r.js optimizer with Django. I've just pushed up the 1.0.0 release.

https://github.com/etianen/django-require

It optimises your project using r.js in a post_process step. There's two 
built-in storage classes, and a mixin that can integrate with any other 
django storage backend (for example, S3BotoStorage from django-storages).

It also supports compiling standalone modules using almond.js.

It's a new package, so all feedback gratefully received!

Everything worked fine, until I couldn't see the Polls entry on the admin

There is a *polls* entry INSTALLED_APPS.

Occasional IntegrityError on m2m fields using PostgreSQL

2012-11-01 Thread Bernardo 
Hello guys,

I can't detect any pattern, maybe 1 in each 1000 thousands edit of a 
certain model returns an IntegrityError on a m2m field. Most of the times 
this field wasn't even modified. When a model is saved I believe django 
always wipes the m2m field and then readds the items, right? I saw django 
calls clear() and then add()s the items. My code then fails with:

IntegrityError: duplicate key value violates unique constraint 
"app_model_m2m_field_key"

It seems like the add of items is performed before the items are cleared, 
which is very weird. I've tried to reproduce it but it's very hard, only 
happens occasionally. Any idea what could cause it? Could maybe setting 
auto commit solve this problem? Thanks in advance

Cheers,
Bernardo

Re: Help me choose OS for django server

2012-11-01 Thread Nikolas Stevenson-Molnar 
Apache+mod_wsgi is one solution (the docs also mention several others).
Their main point is that you shouldn't serve static content via Django.
Ideally, you'd serve static content from another server entirely or via
a CDN. If you are serving files + app on the same server, I think it's
fine to use nginx for both since unlike the Apache+mod_wsgi setup, nginx
isn't actually running the Django app, but simply acting as a proxy.

I used MyForm as an example, the actual class is

class McdLoad(models.Model):
"""A model representing an MCD load uploaded to the server, either by the
UI or by a blade."""
version = models.CharField(primary_key=True,
   max_length=32)
mcdload = models.FileField(upload_to='ftproot',
   blank=True)
fromversions = models.CharField(max_length=4096, default='')
remove_load = models.BooleanField(default=False)

def __str__(self):
return "%s:%s" % (self.version, self.fromversions)

class Meta:
db_table = 'mcdloads'

The view code looks like...

mcdload = McdLoad.objects.get(version=version)
if request.method == 'POST':
log.info("in a POST request")
form = McdLoadForm(request.POST, instance=mcdload)
if form.is_valid():
log.debug("yay, the form is valid")
form.save()

The logs indicate that is_valid() returned True.

unable to save ModelForm with primary key change

2012-11-01 Thread msoulier 
Hi,

I'm trying to modify a model instance, specifically the field which is
the model's primary key. When I save, nothing seems to happen.
Everything in cleaned_data is good, but the model is not updated. No
exception is thrown, the field isn't updated, nothing.

All I'm doing is

form = MyForm(request.POST, instance=model_instance)
if form.is_valid():
form.save()

I'm thinking that this might be an issue with respect to how sqlite
handles changes to primary key fields. Perhaps I'm handling the change
incorrectly. Help appreciated.

Using Django 1.4.1 with python-sqlite2 2.6.3 and 3.6.20.

Thanks,
Mike

The error message says that you have not added "django.contrib.auth"
to INSTALLED_APPS in your settings.py, as far as I can tell.

However, I have no experience of Django on app engine. App engine uses
a customized version of Django, since App Engine does not support
relational databases. This "django-nonrel" (non relational) may not
behave in a way compatible with the tutorial, I don't know. If you are
just starting with Django, I would stick to a more standard Django
setup.

Cheers

Tom

Hi, if you are using the Admin site contrib application you can do this :

https://docs.djangoproject.com/en/dev/topics/auth/#adding-userprofile-fields-to-the-admin

That way whenever you create a user, you'll have the inlined form that
belongs to
your user profile and you can simply check the is_admin checkbox.

Re: Easy way to make all form fields read only?

I would suggest you adding Boolean field to your UserProfile model like

and then in the templates do something like:

{% if user.is_authorized %}



{% else %}
