Question

views.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:\Users\azhar\.virtualenvs\Django_and_Rest-YRrszWnq\lib\site-packages\rest_framework\routers.py", line 152, in get_routes
    extra_actions = viewset.get_extra_actions()
AttributeError: 'function' object has no attribute 'get_extra_actions'

many solution available for how to use get_extra_actions in class View but I want to use it in poll function please help me out

Answer 1

poll 是一个 function based view, not a viewset。所以你不能把它注册到路由器上。可以直接在视图中使用：

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