Error with rules on CreateView introduced in 1.4 #85
Description
https://github.com/dfunckt/django-rules/blob/master/rules/contrib/views.py#L37
Using self.get_object will introduce an error when using rules on a view that inherits from CreateView. This is because CreateView does inherit SingleObjectMixin and does have a get_object callable, but it will throw an exception when its get_object is called:
AttributeError: Generic detail view {InheritsFromCreateView} must be called with either an object pk or a slug.
