Django model not saving when calling save()

问题

so i am trying to save a django model, and for some reason i am only getting a 500 internal server error. the thing is,

if i comment the social_auth.save() it works and i can manipulate the object, but not save it

why is this happening? i am using django tastypie and i am trying to save a django-social-auth instance.

def obj_create(self, bundle, request=None, **kwargs):
    try:
        #this is not supposed to upgrade password
        bundle = super(UserResource, self).obj_create(bundle)
        bundle.obj.save()
        if bundle.data.get('extra_data') != None:
            print bundle.data.get('extra_data')
            fb_id = bundle.data.get('extra_data')['id']
            #social_auth=UserSocialAuth(user_id = bundle.obj, provider=bundle.data.get('provider'),uid=fb_id,extra_data=bundle.data.get('extra_data') )
            social_auth=UserSocialAuth()
            social_auth.user_id = bundle.obj
            social_auth.provider=bundle.data.get('provider')
            social_auth.uid=fb_id
            social_auth.extra_data=bundle.data.get('extra_data')


            print "social: ",social_auth.extra_data
            social_auth.save()

    except IntegrityError:
        raise BadRequest('Username already exists')

    return bundle

回答1:

if bundle.obj is of type User, then social_auth.user_id = bundle.obj is wrong and should be social_auth.user = bundle.obj

also ensure you are not in this case:

django-social-auth HTTP 500
