I have the following in xsd_messages/forms.py
import xsd_training.models
class UpdateRequestForm(forms.Form):
lesson = forms.ModelChoiceField(
queryset=xsd_training.models.Lesson.objects.all())
This gives the error:

However models does exist as proven using the shell:

What's going on?
You've got a circular reference: members.models imports training.models, which imports messages.views, which imports mesages.forms, which imports training.models... that circularity can't be resolved, so Python reports an error.
You need to break that chain. Without seeing the code I can't help you more, but it is deeply suspicious that a models file imports a views file: that really shouldn't happen.
Moved import xsd_messages.views in xsd_training.models to inside a function rather than at the top of the file.

I cannot figure how to import correctly an existing Django project in Eclipse/Pydev, and I can't find my way in the documentation of Pydev. My question is pretty simple : I have an existing project from a different computer, that I want to migrate on a new one.
I installed Eclipse and Pydev on the new machine, and everything seems normal for a new project: I can create a new Django project and run it without issue. I also have been able to import my pre-existing project, but when I run the project, I encounter the following error :
Finding files... done.

Many thanks!
I wanted to add the first model to an already working app, and now I can't start it because it always gives AppRegistryNotReady. This does only happen, if my model MailLog is child of models.Model.
from __future__ import unicode_literals
from django.db import models
#class MailLog(models.Model): # like this, it crashes
class MailLog(): # like this, it works
# Field definitions
recipient = models.EmailField()
created = models.DateTimeField(auto_now_add=True)
template = models.CharField(max_length=500)
error = models.TextField(null=True)
def __str__(self):
return self.recipient+" "+self.template+"("+str(self.created)+")"
The error occurs no matter what's inside the class, even if there is only a pass. However, I can import my models in the admin.py, and it crashes when I import from a file I called core.py. That file looks like this:
import boto3
from botocore.exceptions import ClientError
from django.template import loader
from django.conf import settings
from .templates import *
from .models import MailLog
The traceback looks like this

You should not be importing Django models in your app's __init__ (or causing them to be imported by importing from core. If you use an empty __init__.py it should stop the error.
I was running my project using Django 1.8 and it was working properly. But then I had to upgrade Django to 1.9 now when I again run my project it gave an error - ImportError: cannot import name get_cache.
python manage.py syncdb

Since I'm new in django and it's my first project, Every hint would be appreciated. ths in advance.
It looks like you might be using a version of Django registration that does not support Django 1.8. You could try installing Django registration redux instead.

I installed simplejson but still same error. Anyone haveing experiences with this tutorial? I did everything exactly as per description…
django.utils.simplejson is deprecated in django 1.7.
Looks like you use old version of the sorl-thumbnail. Current version of sorl-thumbnail supports django 1.7 so try to update this library.
