Pregunta Enfrentamientos de accesorios inversos Django


Así que aquí estoy teniendo muchos problemas con los enfrentamientos de acceso inverso. Pensé que estaba siendo muy inteligente y DRY con la estructura de mi modelo para poder usar user.profile para cualquier tipo de perfil, o para utilizar el perfil de proveedor para cualquiera de los proveedores ... pero estoy recibiendo errores de clash por todo el lugar .

Miren mi código y vean si hay alguna forma de arreglarlo, así puedo usar el perfil de usuario sin necesidad de saber qué tipo de perfil (y también proporcionar. Perfil sin necesidad de saber qué tipo de proveedor)? O simplemente me dice que lo que intento hacer es imposible y ¿hay alguna solución mejor?

related_namedebe ser único Le estás dando el mismo nombre a todos related_namees

Intenta cambiarles el nombre así:

user = models.OneToOneField(User, related_name="custom_user_profile", primary_key=True)
#..
provider = models.OneToOneField(Provider, related_name='user_ind_provider_profile')
#..
provider = models.OneToOneField(Provider, related_name='user_org_provider_profile')
