put 方法不适用于 RetrieveUpdateDestroyAPIView Django Rest Framework Angular

Question

我正在尝试在 Django 休息框架中发出放置请求。我的视图继承自 RetrieveUpdateDestroyAPIView class。

我在前端使用 angular 在后端使用 django rest。

这是错误：

Failed to load resource: the server responded with a status of 405 (Method Not Allowed)
ERROR 
detail:"Method "PUT" not allowed."

这是从 angular 端到 django rest

的 put 请求的完整实现

editcity(index){
    this.oldcityname = this.cities[index].city;
     const payload = {
      citypk: this.cities[index].pk,
      cityname: this.editcityform.form.value.editcityinput
    };
     this.suitsettingsservice.editcity(payload, payload.citypk)
       .subscribe(
         (req: any)=>{
           this.cities[index].city = req.city;
           this.editcitysucess = true;
           // will have changed
           this.newcityname = this.cities[index].city;
         }
       );
  }

正在调用的服务

editcity(body, pk){
    const url = suitsettingscity + '/' + pk;
    return this.http.put(url, body);

正在映射的 url django 端：

url(r'^city/(?P<pk>[0-9]+)',SearchCityDetail.as_view())

风景class

class SearchCityDetail(RetrieveUpdateDestroyAPIView):
    queryset = SearchCity.objects.all()
    serializer_class = SearchCitySerializer

RetrieveUPdateDestoryAPIView 文档：

http://www.django-rest-framework.org/api-guide/generic-views/#updatemodelmixin

检索UpdateDestroyAPIView 用于读写删除端点以表示单个模型实例。

提供 get、put、patch 和 delete 方法处理程序。

扩展：GenericAPIView、RetrieveModelMixin、UpdateModelMixin、DestroyModelMixin

RetrieveUpdateDestroyAPIView 源代码：

class RetrieveUpdateDestroyAPIView(mixins.RetrieveModelMixin,
                                   mixins.UpdateModelMixin,
                                   mixins.DestroyModelMixin,
                                   GenericAPIView):
    """
    Concrete view for retrieving, updating or deleting a model instance.
    """
    def get(self, request, *args, **kwargs):
        return self.retrieve(request, *args, **kwargs)

    def put(self, request, *args, **kwargs):
        return self.update(request, *args, **kwargs)

    def patch(self, request, *args, **kwargs):
        return self.partial_update(request, *args, **kwargs)

    def delete(self, request, *args, **kwargs):
        return self.destroy(request, *args, **kwargs)

Answer 1

您 SearchCityListCreate 的 URL 模式匹配 /city/x/ 因此您的请求被错误的视图处理。

您通过切换顺序解决了问题，但更好的解决方法是确保您的正则表达式具有 ^ 和 $ 分别标记 URL 的开头和结尾.

url(r'^city$', SearchCityListCreate.as_view()),
url(r'^city/(?P<pk>[0-9]+)$',SearchCityDetail.as_view()),

Answer 2

我需要颠倒我所在城市的顺序urls

原来如此，pk的城市url从未被占领过。

不好：

url(r'city', SearchCityListCreate.as_view()), # create city list url
url(r'city/(?P<pk>[0-9]+)/$',SearchCityDetail.as_view()),

好：

 url(r'city/(?P<pk>[0-9]+)/$',SearchCityDetail.as_view()), 
 url(r'city', SearchCityListCreate.as_view()), # create city list url

您可以使用 rest_framework class 视图`class country_detail(APIView) 来实现它： def get_object(self,pk): 尝试： return CountryModel.objects.get(pk=pk) 除了 CountryModel.DoesNotExist：提高 Http404

def get(self,request,pk,format=None):
    country=self.get_object(pk)
    serializer=CountrySerializer(country)
    return Response(serializer.data,status=status.HTTP_200_OK)
def put(self,request,pk,format=None):
    country=self.get_object(pk)
    serializer=CountrySerializer(country,data=request.data)
    if serializer.is_valid():
        serializer.save()
        return Response(serializer.data,status=status.HTTP_200_OK)
    return Response(serializer.errors,status=status.HTTP_400_BAD_REQUEST)
def delete(self,request,pk,format=None):
    country=self.get_object(pk)
    country.delete()`
