Question

I’m using a hand built (Postgres) database with Django. With ‘inspectdb’ I was able to automatically create a model for it. The problem is that some tables have multiple primary keys (for many-to-many relations) and they are not accessible via Django.

What’s the best way to access these tables?

Answer 1

There is no way to use composite primary keys in Django’s ORM as of now (up to v1.0.2).

I can only think of three solutions/workarounds:

1. There is a fork of django with a composite pk patch at github that you might want to try.
2. You could use SQLAlchemy together with Django.
3. You have to add a single field primary key field to those tables.
