Django Rest,如何更新视图集中对象的单个字段?我得到必填字段的 IntegrityError
Django Rest, How to update a single field of the object in viewset? I get IntegrityError for the required fields
现在我有一个很大的目录对象,我想根据一个请求修改它的一个字段。(其余部分将保持不变)。我有必填字段,因此在执行 PATCH 请求时出现此错误。
null value in column "team_id" of relation "Catalogs_catalog" violates not-null constraint
DETAIL: Failing row contains (ecf8ede4-1438-441b-8e45-152658512d27, null, [], {}, [], Europe/Moscow, t, null, ["a@a.com"]).
我将 viewset 用于目录视图,并向其添加了一个额外的操作,以便我可以发送 PATCH 请求来更新该字段。
Views.py
@action(methods=['patch'], detail=True, url_path='add_to_whitelist', url_name='add_to_whitelist')
def add_to_whitelist(self, request, pk=None):
catalog = self.get_object()
users_to_add = request.data
serializer = WhiteListUpdateSerializer(data=users_to_add, partial=True)
if serializer.is_valid():
serializer.save()
return Response({"message": "Saved the new white list."}, 201)
return Response({"message":"Error creating white list.", "error": serializer.errors}, 400)
Serializers.py
class WhiteListUpdateSerializer(serializers.ModelSerializer):
class Meta:
model = Catalog
fields = ('whitelist_users',)
partial=True
或重写 partial_update 无效。我是 DRF 的新手,我在这里缺少什么?
改变
WhiteListUpdateSerializer(data=users_to_add, partial=True)
至
WhiteListUpdateSerializer(catalog, data=users_to_add, partial=True)
