You can use model inheritance
class SomeCommonNameHere(models.Model):
title = models.CharField(max_length=100)
body = models.TextField()
class Casts(SomeCommonNameHere):
somecastfield = models....
class Articles(SomeCommonNameHere):
somearticlefield = models...
class Faves(models.Model):
post = models.ForeignKey(SomeCommonNameHere)
user = models.ForeignKey(User,unique=True)
you can then access the subclass' specific fields by referencing:
#where fave is an instance of Faves...
fave.post.articles.somearticlefield...
or
fave.post.casts.somecastfield...
You may also want to look at proxy classes.
