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


i want create object contains 2 links users. example:

class gameclaim(models.model):     target = models.foreignkey(user)     claimer = models.foreignkey(user)     isaccepted = models.booleanfield()

but getting following errors when running server:

  • accessor field 'target' clashes related field 'user.gameclaim_set'. add related_name argument definition 'target'.

  • accessor field 'claimer' clashes related field 'user.gameclaim_set'. add related_name argument definition 'claimer'.

can please explain why getting errors , how fix them?

you have 2 foreign keys user. django automatically creates reverse relation user gameclaim, gameclaim_set. however, because have 2 fks, have 2 gameclaim_set attributes, impossible. need tell django name use reverse relation.

use related_name attribute in fk definition. e.g.

class gameclaim(models.model):     target = models.foreignkey(user, related_name='gameclaim_targets')     claimer = models.foreignkey(user, related_name='gameclaim_users')     isaccepted = models.booleanfield()
