Error report when trying to run ./manage.py migrate

Using django-dev version 1.8.dev20140509044810

When tried in Django 1.7b3, ./manage.py migrate gives,

/usr/local/lib/python2.7/dist-packages/allauth/socialaccount/admin.py:12: RemovedInDjango18Warning: Creating a ModelForm without either the 'fields' attribute or the 'exclude' attribute is deprecated - form SocialAppForm needs updating
  class SocialAppForm(forms.ModelForm):

CommandError: System check identified some issues:

ERRORS:
socialaccount.SocialApp.sites: (fields.E300) Field defines a relation with model 'Site', which is either not installed, or is abstract.

The problem is already addressed here https://github.com/pennersr/django-allauth/pull/588. Please update the version or provide instructions for installing from the git repo

588 is released as part of 0.17.0

The same error message shows for 1.7 when 'django.contrib.staticfiles' is not in INSTALLED_APPS

[eezis]

The error appears when using Django 1.7 & django-allauth v 0.18.0 (regarding the preceding message, the error occurs even when django.contrib.staticfiles' is in INSTALLED_APPS).

FIX the error by adding 'django.contrib.sites' to INSTALLED_APPS, then adding the allauth apps . . .

'django.contrib.sites',
'allauth',
'allauth.account',
'allauth.socialaccount',
'allauth.socialaccount.providers.facebook',

I had this problem. I missed the django.contrib.sites. Thanks eezis.

[sheeshmohsin]

Thanks for this answer, I also had this problem.

[jairnet]

Gracias, solo fue añadir 'django.contrib.sites', y pude hacer la migración con: python manga.py migrate para que funcionara la app django-allauth

I had the same issue and by simply adding: 'django.contrib.sites', to the installed_apps resolved it.
