17002	ManyToManyField through a model which extends some other model	Mitar	InvalidInterrupt	It seems that currently it is impossible to create a ManyToManyField through a model which extends some other model. Django assumes that all fields are accessible in the given model and does not traverse the model hierarchy. This means that it is impossible to use inheritance to prevent data (and code) duplication and have a normalized database.
