405 "Method POST is not allowed" in Django REST framework

Question

I am new in Django REST framework. Can someone explain why I get such error, if I make a POST request to '/api/index/'

405 Method Not Allowed
{"detail":"Method \"POST\" not allowed."}

My code is following:

# views.py
class ApiIndexView(APIView):
    permission_classes = (permissions.AllowAny,)

    def post(self, request, format=None):
        return Response("ok")

# urls.py
urlpatterns = [
    url(r'^api/index/$', views.ApiIndexView.as_view()),
]

# settings.py
REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.DjangoModelPermissions',
    ),
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.TokenAuthentication',
    )
}

But if I add <pk> into my pattern, everything works fine:

# views.py
class ApiIndexView(APIView):
    permission_classes = (permissions.AllowAny,)

    def post(self, request, pk, format=None):
        return Response("ok")

# urls.py
urlpatterns = [
    url(r'^api/index/(?P<pk>\d+)/$', views.ApiIndexView.as_view()),
]

I am completely confused. Why it's necessary to use <pk> and is there a way to avoid the use of this parameter in the URL pattern?

Strange. The code you posted is working for me. Is this the full code? — ilse2005, Mar 15 '16 at 12:49
Not exactly, I placed the parts that I find important. Any idea, where I can be wrong? — Fomalhaut, Mar 15 '16 at 12:59
Well I copied the code from your question and it works. There has to be some other problem. What DRF version are you using? — ilse2005, Mar 15 '16 at 13:10
Thanks, I found the problem. I just included `url(r'^api/', include(views.router.urls))` before and the `router` contains a pattern called `index`. In other words I had another view which took my response and rejected it cause of method = POST. — Fomalhaut, Mar 15 '16 at 13:32
@Fomalhaut Thank you for including your solution! I made the same mistake. — ThePadawan, Jan 08 '18 at 16:04

Make sure that you have "POST" in http_method_names. Alternatively, you can write it like this:

def allowed_methods(self):
    """
    Return the list of allowed HTTP methods, uppercased.
    """
    self.http_method_names.append("post")
    return [method.upper() for method in self.http_method_names
            if hasattr(self, method)]

You need to change just:

# views.py
class ApiIndexView(UpdateView):
    permission_classes = (permissions.AllowAny,)

    def post(self, request, format=None):
        return Response("ok")

class ApiIndexView(APIView)

instead of this please import from rest_framework import generics and change it to

class ApiIndexView(generics.ListCreateAPIView)

There are many generic views. ListCreateAPIView is used for GET and POST and CreateAPIView is used only for POST methods

Your own comment is right. You just included the index url before. And that main view recieve url parameter for retreiving objects, so your new view is interpreted as param. I had the same problem in urls.py:

router = DefaultRouter()
router.register(r'', views.MainViewSet, basename='index')
router.register(r'other_view', views.OtherViewSet, basename='typeservice')

Solution:

router = DefaultRouter()
router.register(r'main', views.MainViewSet, basename='index')
router.register(r'other_view', views.OtherViewSet, basename='other_view')

Is allways better not using empty spaces in url names.

So, instead of this:

router.register(r'', views.SomeViewSet, basename='index')

Do this:

router.register(r'some-url-name', views.SomeViewSet, basename='index')
