How does django register management commands

问题

I'm having a weird issue with something in a deployed django app (long story). Something that might help me is to know:

How django goes about detecting and maintaining a list of active management commands?

回答1:

Some things you should consider if you have troubles executing a management command:

1. The app containing the command has to be in settings.INSTALLED_APPS.
2. To be recognized as an app the package has to contain a models.py (although it can be empty).
3. All packages need to have an __init__.py file (your app's directory as well as the management and command folder).
4. Sometimes Django seems to be choking on something like an ImportError that doesn't get displayed properly - so it might help to open a manage.py shell and try something like import MyCommand from myapp.management.commands.mycommand.

It looks for any module under management.commands inside installed applications. See https://docs.djangoproject.com/en/dev/howto/custom-management-commands/ for mor details.
