如何解决Django外键未更新

嗨，大家好，我是Django的新手，我正在努力解决一个容易解决的问题。这是我的UserSerializer：

SELECT *
FROM  mytable mt
WHERE mt.startdate >= @Startdate 
      and mt.enddate <= @Enddate
      and mt.startdate  >= '20180101';

这是我的GenericAPIView：

IF @Startdate < '20180101' SET @Startdate = '20180101';

SELECT *
FROM  mytable mt
WHERE mt.startdate >= @Startdate 
      and mt.enddate <= @Enddate;

前端发送的请求是这样的：

class UserSerializer(serializers.ModelSerializer):
    role = RoleSerializer(many=False)

    class Meta:
        model = User
        fields = ['id','first_name','last_name','email','password','role','role_id']
        extra_kwargs = {'password': {'write_only': True},}

除class UserGenericAPIView(generics.GenericAPIView,mixins.UpdateModelMixin): serializer_class = UserSerializer queryset = User.objects.all() def put(self,request,pk=None): return self.partial_update(request,pk)以外的所有字段均发生更改... 知道什么是更新role_id的最佳方法吗？
