Django generic relation 필드는 arg가 전달되지 않을 때 all()이 예기치 않은 키워드 인수를 얻음을보고합니다.

Question

다른 모델에 연결할 수있는 모델이 있습니다.

다른 모델에서이 모델과 일반적인 관계를 만들고 있습니다.

flags = generic.GenericRelation(Flag) 

그래서 같이이 일반적인 관계에서 개체를 얻을려고 :

self.flags.all() 

이 다음과 같은 예외가 발생합니다 내가 잘못했을 무엇

>>> obj.flags.all()   
Traceback (most recent call last):

? GenericRelation을 만들 때

Answer 1

당신은 object_id_field 및 content_type_field을 정의해야

flags = generic.GenericRelation(Flag, object_id_field="object_pk", content_type_field="content_type")
