属性错误：'function'对象在函数视图中没有属性'get_extra_actions'

Question

视图.py

@api_view(['GET', 'POST'])
def poll(request):
if request.method == "GET":
question = Question.objects.all()
serializer = QuestionSerializer(question, many=True)
return JsonResponse(serializer.data, safe=False)
elif request.method == "POST":
data = JsonParser.parse(request.POST)
serializer = QuestionSerializer(data=data)
if serializer.is_valid():
serializer.save()
return JsonResponse(serializer.data, status=201)
return JsonResponse(serializer.errors, status=400)

api_urls.py

from django.contrib import admin
from django.urls import path, include
from . import views
from rest_framework import routers

router = routers.DefaultRouter()
router.register(r'poll', views.poll, basename='poll')
urlpatterns = [
path('poll/', include(router.urls)),
]

错误

File "C:Usersazhar.virtualenvsDjango_and_Rest-YRrszWnqlibsite-packagesrest_frameworkrouters.py", line 152, in get_routes
extra_actions = viewset.get_extra_actions()
AttributeError: 'function' object has no attribute 'get_extra_actions'

许多解决方案可用于如何在类视图中使用get_extra_actions，但我想在轮询功能中使用它，请帮助我解决

poll是基于函数的view，而不是viewset。所以你不能把它注册到路由器上。您可以直接在视图中使用它：

urlpatterns = [
path('poll/', views.poll),
]
