我的django api view.py未显示列表并创建新列表

如何解决我的django api view.py未显示列表并创建新列表

你好，开发人员我是django的初学者，我正在学习一个教程，他在其中创建了具体的视图类并将它们转换为viewset.ModelViewSet类。他在urls.py中使用默认路由器

我的应用程序显示具有视图集的文章列表，但未使用ArticleViewSet(viewset.ModelViewSet)执行post方法 所以我对使用viewset感到困惑 这是我的使用具体视图类的api / view.py文件，其中我使用具体视图类**

class ArticleListView(ListAPIView):
       queryset = Articles.objects.all()
       serializer_class = ArticleSerializer

class ArticleDetailView(RetrieveAPIView):
      queryset = Articles.objects.all()
      serializer_class = ArticleSerializer


class ArticleUpdateView(UpdateAPIView):
      queryset = Articles.objects.all()
      serializer_class = ArticleSerializer

class ArticleDeleteView(DestroyAPIView):
      queryset = Articles.objects.all()
      serializer_class = ArticleSerializer
   
class ArticleCreateView(CreateAPIView):
    permission_classes = []
    #parser_classes = (FormParser,MultiPartParser,FileUploadParser )
    serializer_class = ArticleSerializer
    queryset = Articles.objects.all()
    #serializer = ArticleSerializer(queryset,many=True)

    def post(self,request):
        serializer = ArticleSerializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        serializer.save()
        return Response(True,status=200)


# class ArticleViewSet(viewsets.ModelViewSet):
#     parser_classes = (FormParser,FileUploadParser )
#     serializer_class = ArticleSerializer
#     queryset = Articles.objects.all()
    

**这是我在Article应用中的网址格式api / url.py

urlpatterns = [
       path('articles',ArticleListView.as_view() name=""),path('xyz',ArticleCreateView.as_view()),path('<pk>',ArticleDetailView.as_view()),path('<pk>/update/',ArticleUpdateView.as_view()),path('<pk>/delete/',ArticleDeleteView.as_view())
    ]
#from articles.api.views import  *
# from rest_framework.routers import DefaultRouter

# router = DefaultRouter()
# router.register(r'',ArticleViewSet,basename='articles')
# urlpatterns = router.urls

**这些是我在设置文件夹**中的urls.py的网址格式

urlpatterns = [
    path('api-auth/',include('rest_framework.urls',namespace='rest_framework')),path('rest-auth/',include('rest_auth.urls')),path('rest-auth/registration/',include('rest_auth.registration.urls')),path('admin/',admin.site.urls),path('accounts/',include('allauth.urls')),path('api/',include('articles.api.urls')),]+ static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)

解决方法

我不确定，我只进行了快速搜索，但是您提供的信息还不完整，但是我认为您应该定义以下函数，以将功能提供给viewSet。

    """
    Example empty viewset demonstrating the standard
    actions that will be handled by a router class.

    If you're using format suffixes,make sure to also include
    the `format=None` keyword argument for each action.
    """

    def list(self,request):
        pass

    def create(self,request):
        pass

    def retrieve(self,request,pk=None):
        pass

    def update(self,pk=None):
        pass

    def partial_update(self,pk=None):
        pass

    def destroy(self,pk=None):
        pass

或者您可以编写自己的视图集而不是覆盖它们

class UserViewSet(viewsets.ViewSet):
    """
    A simple ViewSet for listing or retrieving users.
    """
    def list(self,request):
        queryset = User.objects.all()
        serializer = UserSerializer(queryset,many=True)
        return Response(serializer.data)

    def retrieve(self,pk=None):
        queryset = User.objects.all()
        user = get_object_or_404(queryset,pk=pk)
        serializer = UserSerializer(user)
        return Response(serializer.data)
