python - django-rest-framework "AttributeError: ' 函数'对象没有属性 'get_extra_actions' ”

Question

django==3.2.4 djangorestframework==3.12.4

博客/serializer.py

from rest_framework import serializers
from .models import Blog

class BlogSerializer(serializers.ModelSerializer):
    class Meta:
        model = Blog
        fields = '__all__'

博客/views.py

from rest_framework import generics
from .models import Blog
from .serializers import BlogSerializer

class BlogListCreateView(generics.ListCreateAPIView):
    queryset = Blog.objects.all()
    serializer_class = BlogSerializer

class BlogRetrieveUpdateDestroyView(generics.RetrieveUpdateDestroyAPIView):
    queryset = Blog.objects.all()
    serializer_class = BlogSerializer

博客/urls.py

router = DefaultRouter()
router.register(r'blogs', BlogListCreateView.as_view(), basename="blogs")
router.register(r'action/<int:pk>', BlogRetrieveUpdateDestroyView.as_view(), basename="action")

urlpatterns = [
    path('', include(router.urls)),
]

当我使用路由器时，它显示AttributeError:'function'对象没有属性'get_extra_actions' 但是当我使用正常的 django urls 路径时它运行成功

博客/urls.py

urlpatterns = [
    path('blog/', BlogListCreateView.as_view(), name="blog"),
    path('blog/<int:pk>', BlogRetrieveUpdateDestroyView.as_view(), name="action"),
]

来自文档:

Because we're using ViewSet classes rather than View classes, we actually don't need to design the URL conf ourselves. The conventions for wiring up resources into views and urls can be handled automatically, using a Router class.

所以你不需要路径是 'action/<int:pk>' 。 'action'就足够了。
