Is it OK to use multiple inheritance with Django abstract models? [closed]

Question

I have three different abstract model base classes . . . I'd like to use them in multiple inheritance, sort of like Mixins. Any problems with this?

E.g.,

class TaggableBase(models.Model):  . . .      class Meta:         abstract = True  class TimeStampedBase(models.Model):  . . .      class Meta:         abstract = True  class OrganizationalBase(models.Model):  . . .      class Meta:         abstract = True  class MyTimeStampedTaggableOrganizationalModel(OrganizationalBase, TimeStampedBase, TaggableBase):  . . .

If you use any fields at all in your class, inherit from models.Model.

Otherwise Django will ignore those fields (the attributes will still be there in Python, but no fields will be created in the DB). Set abstract = True to get "mixin" like behavior (i.e. no DB tables will be created for the mixins but for the models using those mixins).

If you don't use any fields, you can just inherit from object, to keep things plain and simple.
