Question

这是urls.py

from django.conf.urls import url, include
from django.contrib import admin

from api import views
from rest_framework.urlpatterns import format_suffix_patterns
from rest_framework import routers

router = routers.DefaultRouter()
router.register('catalogs',views.CatalogView,'catalog')
router.register('companies',views.CompanyView)
router.register('users',views.UserView)

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'', include(router.urls)),
]

以下是错误：

这是我的serializers.py

class CatalogSerializer(serializers.ModelSerializer):
    # company_details = CompanyData(many=True)
    total_pieces = serializers.SerializerMethodField()
    total_price = serializers.SerializerMethodField()
    # company = CompanySerializer(source='company_name', read_only=True)
    # company_name = serializers.CharField()

    class Meta:
        model = Catalog
        fields = ('name','no_of_pcs','per_piece_price','company_name','total_pieces','total_price')
        #depth = 1

        def to_representation(self, instance):
            rep = super(CatalogSerializer, self).to_representation(instance)
            rep['company'] = {
                                  "company_name":instance.company_name.name,
                                  "phone_number":instance.company_name.phone_number,
                                  "company_id":instance.company_name.id
                             }
            return rep

        def get_total_pieces(self, obj):
            totalpieces = Catalog.objects.aggregate(total_pieces=Count('no_of_pcs'))
            return totalpieces["total_pieces"]

        def get_total_price(self, obj):
            totalprice = Catalog.objects.aggregate(total_price=Sum('per_piece_price'))
            return totalprice["total_price"]

这是我的views.py

from rest_framework.decorators import api_view
@api_view(['GET', 'POST'])
def CatalogView(request):
    if request.method == 'GET':
        catalogs = Catalog.objects.select_related('company_name')
        serializer = CatalogSerializer(catalogs, many=True)
        return Response(serializer.data)

    elif request.method == 'POST':
        serializer = SnippetSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

Django rest框架为什么显示：

AttributeError：“函数”对象没有属性“ get_extra_actions”错误。

为什么显示：

AttributeError：“函数”对象没有属性“ get_extra_actions”错误。

请检查。
谢谢...
