How to use ArrayField in Django using PostgreSQL DB?

Question

I want to do this import in my django models.py:

from django.contrib.postgres.fields import ArrayField

I read this documentation https://docs.djangoproject.com/en/dev/ref/contrib/ and I added 'django.contrib.postgres' into my INSTALLED_APPS in settings.py, but when I try to sync my db or to runserver I got "ImportError: No module named postgres"

Is there something else I should do or install? django.contrib.postgres is part of the core distribution right?

This is traceback:

django.contrib.postgres will be a part of 1.8 release.

Ou thanks, do you know if there is other way of using arrays in postgresql from django?

Fortunately there are several unofficial implementations postgresql arrays in django. One of the most notable being djorm-pgarray. Another option is django-dbarray when Django 1.8 eventually gets rolled out, migration shouldn't be too difficult.
