22280	"""Conflicting models in application"" RuntimeError for same model with different paths"	Daniel Hahler	nobody	"When I run tests using `manage.py test`, the test file `project/app/tests.py` is used/imported with `__name__ = ""project.project.app.test""`.

When using a relative import in tests.py then, the model appears to get registered as `project.project.app.model`.

After the database for the tests is being setup, I get the following error:

> RuntimeError: Conflicting 'model' models in application 'app': <class 'app.models.Model'> and <class 'project.project.app.models.Model'>.

It refers to the same Model, but with different class paths.

This is triggered by / caused when using an relative import from the tests.py file: `from .models import Model`.

I am running manage.py from the first ""project"" directory.

`sys.path` contains the directory `.../project/project` and not the directory where `project.project.app` would be rooted.

With Django 1.6 the `__name__` of tests.py during the import is the same, but there's no error, since there is no apploader that verifies uniqueness using the labels/names.

I could not reproduce it with a simple new project/app in Django 1.7.
