Django: Why do some model fields clash with each other?

Question

I want to create an object that contains 2 links to Users. For example:

class GameClaim(models.Model):
    target = models.ForeignKey(User)
    claimer = mod         


        

Answer 1

Sometimes you have to use extra formatting in related_name - actually, any time when inheritance is used.

class Value(models.Model):
    value = models.DecimalField(decimal_places=2, max_digits=5)
    animal = models.ForeignKey(
        Animal, related_name="%(app_label)s_%(class)s_related")

    class Meta:
        abstract = True

class Height(Value):
    pass

class Weigth(Value):
    pass

class Length(Value):
    pass

No clash here, but related_name is defined once and Django will take care for creating unique relation names.

then in children of Value class, you'll have access to:

herdboard_height_related
herdboard_lenght_related
herdboard_weight_related
