How to have two models reference each other Django
The Django documentation for the ForeignKey field states:
If you need to create a relationship on a model that has not yet been defined, you can use the name of the model, rather than the model object itself.
So in your case, that would be:
class Game(models.Model): # Other fields... on = models.ForeignKey('Member', blank = True)class Member(models.Model): # Other fields... game = models.ForeignKey(Game)
You don't need to have the two models reference each other with foreign keys. Remove the line:
on = models.ForeignKey(Member, blank = True) #<----and logically your Member's will still be associated to different Game's (and this makes more sense because a member can belong to one game at a time, whereas a game can have more than one member).
You can use reverse relation to figure out which members are on a particular game.
