Social Authentication and ContentTypes

telenieko commented 5 years ago

Hi,

If you follow the doc about socialauth you will end up with a non working setup, at least when enabling google OAuth2

Traceback (most recent call last):
  File "manage.py", line 28, in <module>

    from django.contrib.contenttypes.models import ContentType

    class ContentType(models.Model):
  File "lib/python3.6/site-packages/django/db/models/base.py", line 95, in __new__
    "INSTALLED_APPS." % (module, name)
RuntimeError: Model class django.contrib.contenttypes.models.ContentType doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

The solution looks obvious: add contenttypes to INSTALLED_APPS. Which you could do in two forms:

You see the error, you are an experienced Django developer so, after instantiating Site() you add:

INSTALLED_APPS += ('django.contrib.contenttypes',)

And you will be greeted with...

table_factory() failed for <class 'django.contrib.contenttypes.models.ContentType'>. table_factory() failed for <class 'django.contrib.contenttypes.models.ContentType'>.

Only then will you think "hey, it's not a plugin, but maybe the right place to put it is Site.get_installed_apps, like: yield 'django.contrib.contenttypes'.

Now it works.

So, that page might explain that contenttypes is needed, and how to add it?

How did you get that error? I cannot reproduce it. What is your output of pip freeze?
