title: generic.Listview does not show in URL list in DRF Viewer
body: <p>I'm missing something, but I don't know what it is.  When I go to the DRF Viewer, alerts is not listed in the possible list of urls. all the other Rest URLs do.</p>
  
  <p>here's my serializer.py:</p>
  
  <pre><code>class OptionSerializer(serializers.ModelSerializer):
      class Meta:
          model = Options
          fields = '__all__'
  
          validators = [
              UniqueTogetherValidator(
                  queryset=Options.objects.all(),
                  fields=('Member', 'skey', 'Time_Period')
              )
          ]
  </code></pre>
  
  <p>api.py:</p>
  
  <pre><code>class OptionViewSet(generics.ListCreateAPIView):
      serializer_class = OptionSerializer
  
      def get_queryset(self):
          """
          This view should return a list of all the options
          for the currently authenticated user.
          """
          user = self.request.user
          return Options.objects.filter(Member=user)
  </code></pre>
  
  <p>and my urls.py:</p>
  
  <pre><code>router = routers.DefaultRouter()
  router.register(r'users', api.UserViewSet)
  router.register(r'groups', api.GroupViewSet)
  router.register(r'currency', api.BitCoinViewSet)
  router.register(r'latest_prices', api.CurrencyLatestViewSet)
  router.register(r'options', api.OptionViewSet.as_view, 'alerts')
  
  urlpatterns = [
      url(r'^admin/', admin.site.urls),
      url(r'^api/', include(router.urls)),
      url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
  
  ]
  </code></pre>
  
  <p>Why does the <code>alert</code> url not show up?  Thanks.</p>
