Description

Hi, I have a non reflexive recursive many to many relation in my app, and thought it'd be cool to have some default validation for this, instead of having to roll my own every time.

The relation I'm talking about is a twitter-like 'follow' relation between users, where users shouldn't be able to follow themselves (thus it's non-reflexive).

It's not entirely clear what you are proposing. Since you have categorised this as database layer, it sounds like you are looking for a keyword argument to be added to ManyToManyField to enforce this validation.

I really don't think this specific validation rule, which only applies to many-to-many relations to the same model, is common enough to warrant support at the database level, so I'm going to close as WONTFIX.
