Django 1.7 adds a new `check` command for models that is called on the
class. As far as I can tell, this is only mentioned (briefly) in the
documentation for the check framework.
https://docs.djangoproject.com/en/1.7/topics/checks/#field-model-and-
manager-checks
If users create a model that has a method `check`, calling `manage.py
check` will fail (because of the conflicting method names).

This is not mentioned in the release notes for Django 1.7 at all and
worked fine in previous versions:
