So, this is an extension of what I asked last week (Why do I need to import a class within this class, instead of at the top of the file?) but after extensive debugging, I feel like it might warrant a new question.
I have a number of modules, all with imports. I suspect there may be a circular import but I haven't been able to find it.
Here's the weird thing:
In one models.py file, I have:
from django.db import models
from django.core.exceptions import ObjectDoesNotExist
from heythere.models import Notification as HeyThere
from heythere.models import NotificationManager as HeyThereManager
from django.contrib.auth.models import User
then some model definitions, including one with a method:
def to_user(self):
try:
return User.objects.get(username=str(self.username))
except ObjectDoesNotExist:
return None
and a little further down:
from ownership.apps.Assets.models import Item
When it's like this, I get AttributeError: 'NoneType' object has no attribute 'objects' (referring to User). So it's set to None, somehow, as opposed to raising a global name XXX is not defined.
BUT THEN, I tried accessing the User right after the import:
me = User.objects.get(username='xxxx')
print me
It printed correctly upon running runserver, so I know it can access User there, but then gave me the error message ImportError: cannot import name Item. How did simply accessing the model cause an import error? (FWIW, Item does have a number of FK relations to User)
What gives?
Traceback when User.objects.get() is included:

Assets/models.py was importing permissions
Permissions was importing Shared.models.Person
Shared/models was importing Assets.models.Item
which was a circular import.
This was corrected by moving from django.contrib.auth.models import User to inside of the Person model. I don't quite understand why--if anyone wants to elaborate and provide a better explanation before I accept my own answer, please do.

I'm looking for a solution to this error in Django. I sent you my forms and my view, and the error is as follows in my app . According to what appears to me in the tracer back, I would mark an error in the views line if form.is_valid() I already looked at a lot of things, but the truth is I'm already lost. I need help with the damn error.

I'm currently working with the Django framework to build a content management system into a company website, and after successfully completing one page, began work on a different page that requires a rich text editor within the admin interface.
Having chosen TinyMCE for the job, I spent a lot of time on Monday trying to get it running correctly, but only managed to include a simple HTMLField(). Having been slightly confused by a number of differing tutorials, I've now encountered an error that I'm struggling to find a solution to, and one which I hoped the StackOverflow community might be able to help with.
Currently, I have the following code:
admin.py
from django.forms import *
from django.db.models import *
from tinymce.widgets import TinyMCE
from models import *
from django.contrib import admin
#class MyModelForm(forms.ModelForm):
#content = forms.CharField(widget=TinyMCE(attrs={'cols': 80, 'rows': 10}))
#class Meta:
#model = MyModel
class MyModelAdmin(admin.ModelAdmin):
form = MyModelForm
admin.site.register(MyModelForm, MyModelAdmin)
The majority of this code has been commented out for debugging purposes, as the problem seems to be with models.py:
models.py
from django import forms
from django.contrib.flatpages.models import FlatPage
from tinymce.widgets import TinyMCE
class MyModelForm(forms.ModelForm):
content = forms.CharField(widget=TinyMCE(attrs={'cols': 80, 'rows' : 30}))
class Meta:
model = FlatPage
This is the traceback I'm being presented with:

As you can see, tinymce appears to be correctly installed, and the problem lies with models.ModelForm
My aim, in case it isn't clear, is to create a simple MyModel model with one content field, editable using the TinyMCE Editor. If you think I could supply any more code to shed more light on the situation, please let me know. Thanks.
I think I'm a bit confused with your model definition, either way I think your error is in this line
admin.site.register(MyModelForm, MyModelAdmin)
unless I'm being fooled by the name MyModelForm you are passing a ModelForm to the register method which takes a models.Model subclass as an argument.
This is really late to the party but this is what you need.
admin.site.register(MyModel, MyModelAdmin)
The MyModelAdmin has the MyModelForm and admin.site.register takes a Model and a ModelAdmin
I am installing a django application module.I am getting this error.
I started another MicroInstance and reinstalled everything but still I am getting this error.

From what I see, the problem is likely to be related to the moca framework.
If your /opt/sana/mrs/admin.py file looks like this then the culprit is likely to be located at line 12 : the created field is refered in the exclude list, but not previously defined.
As I'm not sure about your needs here are some solutions you can try :
Re-install or update your moca frameword ;
Add a piece of code before the execute definition (not sure what's type it should be though) :
from django.db import models # You may also place it in the top of the file
created = models.DateField(blank=True, null=True)
Remove the created item from the exclude list (not sure about the impact though)
Hope it helps,
I'm trying to use django's reverse() function in definition of django form for my custom widget, but am getting an error:
ImproperlyConfigured
The included urlconf urls doesn't have any patterns in it
Here is the code:
class WorkForm(forms.Form):
# ...
category = forms.ChoiceField(
required=True,
label=_('Category'),
help_text=_('Select most appropriate category for your work.')
)
subcategory = forms.ChoiceField(
widget=DependantChoiceWidget(
default_value=_('Select category first'),
data_source_url=reverse('works-json-categories'),
# data_source_url='', -- it works this way
depends_on='category_id'
),
required=True,
label=_('SubCategory'),
help_text=_('Which subcategory suits your work best.')
)
I am pretty sure, that my 'works.urls' is configured properly, since all other pages work as expected.
Is there a reason, why I cannot use reverse() in form definition? Does it have something to do with when this code runs? Is there a way to fix this, or the only choice here is to hardcode the URL?

The problem might be that the form is defined before the urls have been loaded.
Django 1.4 will have a reverse_lazy feature that would solve this problem. You could implement it in your project yourself (see changeset 16121).
Alternatively, you could set the widget in your forms __init__ method instead. Then the reverse call happens when the form is created, after the urls have loaded.
class WorkForm(forms.Form):
# ...
subcategory = forms.ChoiceField(
required=True,
label=_('SubCategory'),
help_text=_('Which subcategory suits your work best.')
)
def __init__(self, *args, **kwargs):
super(WorkForm, self).__init__(*args, **kwargs)
self.fields['subcategory'].widget=DependantChoiceWidget(
default_value=_('Select category first'),
data_source_url=reverse('works-json-categories'),
depends_on='category_id'
),
I'm new to django and Google App Engine, and I'm having trouble with using the datastore. Every time I make a query, such as
db.GqlQuery("SELECT * FROM Listing ORDER BY date DESC LIMIT 10")
I receive the error:
'WSGIRequest' object has no attribute 'user'
This error seems to be generated in context_processors.py within the django core. Now, the advice I've found on the Internet said to comment out user-related INSTALLED_APPS and MIDDLEWARE_CLASSES, but this does not seem to help. My code looks like this:
MIDDLEWARE_CLASSES = (
# 'django.middleware.common.CommonMiddleware',
# 'django.contrib.sessions.middleware.SessionMiddleware',
# 'django.contrib.auth.middleware.AuthenticationMiddleware',
# 'django.middleware.doc.XViewMiddleware',
)
INSTALLED_APPS = (
# 'django.contrib.auth',
'django.contrib.contenttypes',
# 'django.contrib.sessions',
'django.contrib.sites',
)
My Listing object is defined as the following (it had a author property earlier, but this is now commented out and the object was redefined with a new name):
class Listing(db.Model):
#author = db.UserProperty()
address = db.StringProperty()
date = db.DateTimeProperty(auto_now_add=True)
coords = db.GeoPtProperty()
Does anyone know what is causing this error, and how to fix it? Is it perhaps a case of having to reset the settings somehow?
UPDATE
The solution suggested by sdolan seems to be to add the following to the settings.py of the app:
TEMPLATE_CONTEXT_PROCESSORS = (
"django.core.context_processors.debug",
"django.core.context_processors.i18n")
This effectively removes the third default processor, django.core.context_processors.auth (which shouldn't be there because for AppEngine we don't want Django's auth component).
Thank you, sdolan, for the solution! hopefully someone else can use it, too. :)
#Nick, I think it's worth putting this golden piece about CONTEXT_PROCESSORS in the tutorial (http://code.google.com/appengine/articles/django.html)
(Original followup to the question)
Have the same problem, looking for solution.... All works fine when settings.py contains
DEBUG = True
but this error pops up (and kills my motivation to proceed with learning) when I switch to
DEBUG = False
