Re: Validation on two user foreign keys

Hi Nicole,

Override the Friendship model's 'save' method to test the unique combination of (initiator, recipient).

Regards,

Hi All,

I have a model called 'Friendship' that includes two foreign keys to User. One is the 'initiator' of the Friendship, the other the 'recipient'.
I want to make sure the Friendship only exists once regardless of who is the recipient and who is the initiator.
Any thoughts on the best way to validate for this?
Should I create a custom manager and override .objects.create() ?

Thanks for your time :)
Nicole
