爲DRF添加另一個路由參數

Question

有一組由Django Rest Framework默認生成的API端點。示例這一個：

^api/^^provinces/(?P<pk>[^/.]+)/$ [name='province-detail'] 

產生http://127.0.0.1:8000/api/provinces/02/這很好。 它使用的實際代碼波紋管：

class ProvinceSerializer(serializers.ModelSerializer): 
    """ Serializer to represent the Province model """ 
    class Meta: 
     model = Province 
     fields = ("name", "code") 

我要增加另一個路線，這樣我可以有例如另一個端點：

^api/^^provinces/(?P<pk>[^/.]+)/(?P<product>[^/.]+)/$ [name='province-product-detail'] 

所以，我可以這樣做http://127.0.0.1:8000/api/provinces/02/apple/和訪問串行器方法中的第二個參數。我試圖這樣做：

class ProvinceSerializer(serializers.ModelSerializer): 
    """ Serializer to represent the Province model """ 
    class Meta: 
     model = Province 
     fields = ("name", "code") 

    @detail_route(methods=['post']) 
    def set_product(self, request, product=None): 
     return product 

Answer 1

我發現我在錯誤的地方使用@detail_route。我們只需要這樣做：

class ProvinceDistrictViewSet(viewsets.ModelViewSet): 
    """ 
    API endpoint that allows users to view or edit province. 
    """ 
    queryset = Province.objects.all() 
    serializer_class = ProvinceDistrictsSerializer 

    # For get provinces 
    @detail_route(methods=['get'], url_path='(?P<product>\d+)') 
    def update_product(self, request, pk, product=None): 
     """ Updates the object identified by the pk and add the product """ 
     queryset = Province.objects.filter(pk=pk) 
     serializer = ProvinceDistrictsSerializer(queryset, many=True, context={'product': product}) 
     return Response(serializer.data, status=status.HTTP_200_OK)
