Django-registration compatibility issue with django 1.7

问题

I've been using [django-registration] (https://bitbucket.org/ubernostrum/django-registration) and now I have started using django 1.7b1 and here is the error I am getting the error copied below. It is being raised from django-registration in models.py:

try:
    from django.contrib.auth import get_user_model
    User = get_user_model()
except ImportError:
    from django.contrib.auth.models import User

and it seems it is being raised because get_user_model() is being called before the app registry is ready. I am not sure if this a compatibility issue or not, if yes is there a simple workaround for this? and if not can you help me identify what I am doing wrong?

RuntimeError: App registry isn't ready yet.

回答1:

Don't use the django-registration available from PyPI. It does not support Django 1.7 and it appears it never will. The repo maintainer has abdicated and the project appears unmaintained.

There is a maintenance fork available on Github which has worked well for me with Django 1.7:

https://github.com/macropin/django-registration

It's available from PyPI as django-registration-redux.

https://pypi.python.org/pypi/django-registration-redux/

You can install using pip:

pip install django-registration-redux

This note addresses your problem.

I think the preferred way to import User is:

from django.conf import settings
User = settings.AUTH_USER_MODEL

EDIT:

Looks like this problem has been noted but the project admin is being difficult about making the change. link. This is a bigger problem with the updates in Django 1.7.

I would say you could either: (1) fork the repo and make the change yourself, or (2) make the changes in your site packages folder after you pip install. The latter version won't work as well if you then push it to another server and install with requirements.txt. Note that if you do option 1 with requirements.txt, you'll want to point it to your repo rather than Django-registration.
