Django django-extensions commands unavailable ( graph_models )
Question: I'm trying to install django-extensions + graphviz + pygraph but i can't. I
have done the following steps ( under Ubuntu ):

    
    
    sudo apt-get install graphviz libgraphviz-dev graphviz-dev python-pygraphviz
    

in the project virtualenv (running python 2.7.2+):

    
    
    source <path to virtualenv>/bin/activate
    pip install django django-extensions
    

if i run

    
    
    which python
    

it selects the python in my virtualenv, so the python i'm using is the right
one. in the virtualenv's site-package i have pygraphviz and django-extensions

    
    
    python manage.py shell
    import django_extensions
    import pygraphviz 
    RUNS OK
    

in my django project i have added 'django_extensions' in my INSTALLED_APPS

But when i run

    
    
    python manage.py help
    

i can't see the commands and they are unavailable.

    
    
    python manage.py graph_models -a -g -o model.png
    Unknown command: 'graph_models'
    Type 'manage.py help' for usage.
    

How can I fix this ? Thanks!


Answer: Run this in `manage.py shell`:

    
    
    from django.conf import settings; 'django_extensions' in settings.INSTALLED_APPS
    

If it doesn't return True, then it means that you didn't add
'django_extensions' properly in INSTALLED_APPS, and that would be the only
reason why Django doesn't find the command.
