dumpdata don't work with sub app

[Fabio Caritas Barrionuevo da Luz <bnafta@…>]

I use django-allauth. The django-allauth has a structure of sub apps.
I need to export data from some of the sub apps, although Django support the sub apps, dumpdata command does not have support to this feature

I have the following structure of directories:

django_project:

manage.py
test_dumpdata_subapp:

init.py
settings.py
...

normalapp:

init.py
models.py
...
subapp:

init.py
models.py
...
submodule:

init.py
anothersubapp:

init.py
models.py
...

On settings.py file:

INSTALLED_APPS = (

...
'normalapp',
'normalapp.subapp',
'normalapp.subapp.submodule.anothersubapp',

)

syncdb works perfectly, but try:

python manage.py dumpdata normalapp normalapp.subapp normalapp.subapp.submodule.anothersubapp

results in this:
CommandError: Unknown model: normalapp.subapp

My test project is attached or can be viewed on github: ​https://github.com/luzfcb/test_dumpdata_subapp

The app-label for a "subapp" (for any app, really) is just the leaf package name, not the full dotted import path. So you should be running python manage.py dumpdata normalapp subapp anothersubapp.

Thank's.
I'm not speaking english language, use google translator for almost everything (I'm still learning). So it was not very clear to me.
It is possible to include an explicit note about it in the documentation and/or help of the dumpdata command?

[Carl Meyer]

Many management commands accept app labels, so it doesn't make sense to document this specifically for dumpdata. It seems like the 1.6 docs don't include a clear definition of "app label" (that I can find); however, this has already been addressed for 1.7 in ​https://docs.djangoproject.com/en/dev/ref/applications/
