Is it possible to make a foreign key to different models?

Question

Django

Let's say in django I have an abstract ArtObject model that stands for a work of art. She has successors Song, Picture, Writing, which are similar but different. I want to add a Review model that fits all 3 models. There is an idea to make 2 IntegerField: one is responsible for the id of what the review is for, the other for the type of this something, but it looks like a crutch, which in fact it is. So, what is the best way to implement this?

Answer 1

First, you can make a ForeignKey on the ArtObject itself. Secondly, your bike is already invented and is called GenericRelation .
