Django django-extensions commands unavailable ( graph_models )

python django graphviz pygraphviz

Solution 1

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.

Solution 2

Actually, if you look at your manage.py's code, you will notice that it sets DJANGO_SETTINGS_MODULES according to your current site: let say "mysite.settings". If you want your manage.py to list additional extensions (e.g. ones from django-extensions or django-evolution) then you must add your project-root's folder to your python path, if not you will only get the bascc manage.py commands.

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!

  Welcome! Is this an existing project? i.e. does python manage.py runserver work ok? Just to confirm - there are no django-extension commands appearing when you run python manage.py help?

  Yes i confirm, no django-extension command is shown

wouldn't python manage.py runserver fail if django_extensions wasn't properly added?

Thanks! the settings.py wasn't imported in the right way... now everything works as expected... THANK YOU!

@pastylegs i think that runserver would just do as if django_extension wasn't there at all. Thank you both for your feedback.

@jpic Yea, I must check that. Well spotted anyway
