관리자 인라인 이름을 얻는 방법 또는 인라인을 변경하는 방법을 정의하는 방법은 무엇입니까?

Question

동일한 모델의 인라인이 2 개 있습니다.

class UsersInlineAdmin(GenericTabularInline): 
    model = CTSportsToCriterias 

class TeamsInlineAdmin(GenericTabularInline): 
    model = CTSportsToCriterias 

class CTSportsToCriterias(models.Model): 
    user_use = models.BooleanField(verbose_name=_('is available to users?'), default=False) 
    team_use = models.BooleanField(verbose_name=_('is available to teams?'), default=False) 

    content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) 
    object_id = models.PositiveIntegerField() 
    content_object = GenericForeignKey() 

    criteria_group = models.ForeignKey(CriteriaGroups, verbose_name=_('criteria group')) 

나는 UsersInlineAdmin (이 경우에 user_use이 True)에서 항목을 제거하고이 항목도 (team_use는도 마찬가지입니다) TeamsInlineAdmin에있는 경우, 장고는 자동으로 TeamsInlineAdmin 인라인에서이 항목을 제거 할 때에 따라 때문에 Django 문서, 코드 :

def save_formset(self, request, form, formset, change): 
    for obj in formset.deleted_objects: 
    ... 

은 모델의 개체를 제공합니다.

if (inline_name == 'UsersInlineAdmin' and not obj.team_use) or \ 
    (inline_name == 'TeamsInlineAdmin' and not obj.user_use): 
    obj.delete() 

: 내 경우 모델이 몇 가지 옵션 (team_use \ user_use)를 가질 수 있기 때문에

그래서, 그것은 가능하다 그런 짓을하기 위해 save_formset에서 inline 이름을 얻으려면?

편집 : 나는 form를 추가하고 나는 경우에 user 항목을 추가 할 때 team의 항목이 이미 존재하는 경우, clean()를 오버라이드 (override)하는 경우는, 장고 True로 DB user_use에 업데이트하지 않습니다 . 대신 Django는 새로운 레코드를 만듭니다.

     # This trick works ok in case when I want to DELETE user's item, 
     # so the trick changes in DB 'user_use' to False, if 'team_use' already exists
