Error: One or more models did not validate:
topics.topic: Accessor for field \'content_type\' clashes with rel         


        

Answer 1

If your models are inheriting from the same parent model, you should set a unique related_name in the parent's ForeignKey. For example:

author = models.ForeignKey('accounts.User', related_name='%(app_label)s_%(class)s_related')

It's better explained in the docs
