Django manage.py do not show commands of an app

Question

I'm using Django 1.4 and have a project similar to the following:

project/
    __init__.py
    app1/
        __init__.py
        models.py
        views.py
        management/
            __init__.py
            commands/
                __init__.py
                ...many commands...
        test/
            __init__.py
            ...many tests...
    app2/
        __init__.py
        models.py
        management/
            __init__.py
            commands/
                __init__.py
                ...many commands...
        test/
            __init__.py
            ...many tests...

where models.py of app2 is an empty file, and both app1 and app2 are listed in INSTALLED_APPS. The problem is that when i run

python manage.py --help

the commands of app1 appears as:

[app1]
command1
command2
...
commandsn

but not those of app2 as if there's no installed app2. And if try to run a command of app2 named app2command it complains Unknown command: 'app2command'. But the tests for both apps can be run, in particular

python manage.py test app2

goes good. Is the problem the fact that app2 has no models?

Answer 1

I have just realized that I have a local settings which overrides INSTALLED_APPS. In settings.py the INSTALLED_APPS contains both app1 and app2 while in local settings app2 was not there.
