일반 외래 키 및 django 1.0 get_or_create : 깨진?

Question

보시다시피 create()는 작동하지만 get_or_create()는 작동하지 않습니다. 내가 여기서 뭔가 분명한 것을 놓치고 있니?

In [7]: f = FeedItem.objects.create(source=u, dest=q, type="greata") 

In [8]: f, created = FeedItem.objects.get_or_create(source=u, dest=q, type="greata")

봐가 다른 get_or_create에로 create 및 get_or_create에 사용되는 논리를 더 source 인수가 없지만 src_object_id 및 src_content_type이야 있지만이 문제를 해결하기 쉽습니다 같은 - (이명 령과 동일) u.content_type로 u.id로 scr_object_id 및 src_content_type 통과 .

try/except & create을 사용하십시오.
