我正在尝试创建一个API视图,但我收到一个错误.有人可以帮忙吗？

urls.py:

app_name = 'ads'
urlpatterns = [
    # ex: /ads/
    url(r'^$', views.ListBrand.as_view(), name='brand_list'),
]

views.py:

from rest_framework.views import APIView
from rest_framework.response import Response
from . import models
from . import serializers


class ListBrand(APIView):
    def get(self, request, format=None):
        brands = models.Brand.objects.all()
        serializer = serializers.BrandSerializer(brands, many=True)
        data = serializer.data
        return Response(data)

更新:这里是错误,这是一个字符串错误.我似乎无法找到它的来源.
