ImportError: cannot import name generic

Question

I am working with eav-django(entity-attribute-value) in django 1.9. Whenever I was executing the command ./manage.py runserver , I got the error :

Unhandled exception in thread started by <function wrapper at 0x10385b500>
Traceback (most recent call last):

    from django.contrib.contenttypes import generic

I tried to import generic by adding:

from django.contrib.contenttypes import generic 

in models.py. Then after few research I found out that generic has been deprecated in Django 1.7 and is no more in Django 1.9. Can anyone tell me in which other library this functionality has been added in Django 1.9 and how to use it?

The django.contrib.contenttypes module has been reorganized in Django 1.7.

Instead of django.contrib.contenttypes.generic.GenericForeignKey you can now use django.contrib.contenttypes.fields.GenericForeignKey. See the sample code in the documentation:
