Django - setUpTestData & Many to Many relationship

I need to add a many-to-many relationship in my setUpTestData sequence so that my tests will run correctly.

According to the docs, Many-to-Many relationships cannot be created until an object has been saved, as the primary key must first exist. This means that I cannot set the relationship in setUpTestData with Model.objects.create() as I do with other variables.

Is there any way to include a Many-to-Many relationship in setUpTestData?
