Django - 为锦标赛创建 model

Question

I have a problem with my model, i don't know how to create model called battle, because i want to choose two users from my database but i don't know how to create it

class battle(models.Model):
    user1 = models.ForeignKey(Debatants, on_delete=models.DO_NOTHING)
    user2 = models.ForeignKey(Debatants, on_delete=models.DO_NOTHING)
    judge = models.ForeignKey(Judges, on_delete=models.DO_NOTHING)
    data = models.DateField(auto_now_add=False, auto_now=False)

I'd appreciate any hint

Answer 1

Try to add unique related name with forign key relationships,

for example

user1 = models.ForeignKey(Debatants, on_delete=models.DO_NOTHING, related_name="battles")

so the Debatants relate to this model as battles
