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>

    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?

Answer 1

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:

https://docs.djangoproject.com/en/1.7/ref/contrib/contenttypes/#generic-relations

Answer 2

This functionality has been moved into the .models and .fields modules. It's just the specific file that is removed; the generic relations functionality still exists, just split into separate files.

Answer 3

Update Django.tagging package from Python's official site, not from Pip source, because Pip does not have the latest version.
