如何將項目設置爲Django Rest框架中的特定Todolist？

我使用django rest框架構建了一個TODO應用程序。我必須有兩種模式，即todolist和todoitem。我可以如何爲特定的todolist設置新的todoitem？我嘗試使用外鍵，但它並沒有制定出來，對不起我的英文不好，任何人都可以請幫我如何將項目設置爲Django Rest框架中的特定Todolist？

我models.py：

class todolist(models.Model): 

    user = models.ForeignKey(User,on_delete=models.CASCADE,default=None) 
    name = models.CharField(max_length=128) 
    creation_date = models.DateField(auto_now=True) 

    def __unicode__(self): 
     return self.name 

class todoitem(models.Model): 
    description = models.CharField(max_length=150) 
    completed = models.BooleanField(default=False) 
    due_by = models.DateField(auto_now=True) 
    parent = models.ForeignKey(todolist,on_delete=models.CASCADE) 

    def _unicode__(self): 
     return self.description

我classviews.py：

class Todolist(LoginRequiredMixin,ListCreateAPIView): 
    serializer_class = listserializer 
    def perform_create(self, serializer): 
     serializer.save(user=self.request.user) 

    def get_queryset(self): 
     self.queryset = todolist.objects.filter(user=self.request.user) 
     return super(Todolist, self).get_queryset() 

class Todolistdetail(LoginRequiredMixin,RetrieveUpdateDestroyAPIView): 
    def get_queryset(self): 
     self.queryset = todolist.objects.filter(user=self.request.user) 
     return super(Todolistdetail, self).get_queryset() 
    serializer_class = listserializer 

class Todoitem(LoginRequiredMixin,ListCreateAPIView): 
    def perform_create(self, serializer): 
     temp = self.queryset(todolist.objects.filter(id=self.kwargs['pk'])) 
     serializer.save(parent=temp) 

    def get_queryset(self): 
     temp = todolist.objects.filter(id=self.kwargs['pk']) 
     self.queryset = todoitem.objects.filter(parent=temp) 
     return super(Todoitem, self).get_queryset() 
    serializer_class = itemserializer 

class Todoitemdetail(LoginRequiredMixin,RetrieveUpdateDestroyAPIView): 
    def get_queryset(self): 
     temp = todolist.objects.filter(id=self.kwargs['list_id']) 
     self.queryset = todoitem.objects.filter(parent=temp) 
     return super(Todoitemdetail, self).get_queryset() 
    serializer_class = itemserializer

我serializers.py ：

class listserializer(serializers.ModelSerializer): 
    user = serializers.ReadOnlyField(source='user.username') 
    class Meta: 
     model = todolist 
     fields = '__all__' 

class itemserializer(serializers.ModelSerializer): 
    parent = serializers.ReadOnlyField(source='todolist.id') 
    class Meta: 
     model = todoitem 
     fields = '__all__'

我urls.py：

from todoapp import classviews 
app_name = "todoapp" 

urlpatterns = [ 
    url(r'^list/$',classviews.Todolist.as_view(),name="list_lists"), 
    url(r'^list/(?P<pk>[0-9]+)/$',classviews.Todolistdetail.as_view(),name="each_list"), 
    url(r'^list/(?P<pk>[0-9]+)/item/$',classviews.Todoitem.as_view(),name="list_items"), 
    url(r'^list/(?P<list_id>[0-9]+)/item/(?P<pk>[0-9]+)/$',classviews.Todoitemdetail.as_view(),name="each_item") 

]

觀點：

from rest_framework.viewsets import ModelViewSet 
class TodoitemViewSet(ModelViewSet): 
    queryset = Todoitem.objects.all() 
    serializer_class = itemserializer 
    permission_classes = (IsAuthenticated)

serializer.py

class itemserializer(serializers.ModelSerializer): 
    class Meta: 
     model=todoitem 
     fields='__all__'

網址：

from rest_framework import routers 
router = routers.DefaultRouter() 
router.register(r'todo_item', TodoitemViewSet) 
urlpatterns = [ 
    url(r'^admin/', admin.site.urls), 
    url(r'^', include(router.urls)), 
]

僅僅指剛發佈數據{'parent':1 'description':'example',....}到www.example.com/todo_item/，父母是你的todolist'id 。
