Fixed #18399 – Added a way to get ContentTypes for proxy models

Browse source 
Added kwargs for_concrete_model and for_concrete_models to ContentType
methods get_for_model() and get_for_models(). By setting the flag to
False, it is possible to get the contenttype for proxy models.

Prior to Django 1.5 :meth:`~ContentTypeManager.get_for_model()` and
:meth:`~ContentTypeManager.get_for_models()` always returned the
:class:`~django.contrib.contenttypes.models.ContentType` associated with the
concrete model of the specified one(s). That means there was no way to retreive
the :class:`~django.contrib.contenttypes.models.ContentType` of a proxy model
using those methods. As of Django 1.5 you can now pass a boolean flag –
respectively ``for_concrete_model`` and ``for_concrete_models`` – to specify
wether or not you want to retreive the
:class:`~django.contrib.contenttypes.models.ContentType` for the concrete or
direct model.
