 Views and Generic Views
 ============================
 
+In this chapter, we will create views using :code:`APIVIew`, and :code:`generics.ListCreateAPIView` and family.
+
+Creating Views with :code:`APIView`
+-----------------------------------------
+
+
 To start with, we will use the :code:`APIView` to build the polls list and poll detail API we built in the chapter, doc:apis-without-drf:.
 
+Add this to a new file :code:`polls/apiviews.py`
+
+.. code-block:: python
+
+    class PollList(APIView):
+        def get(self, request):
+            polls = Poll.objects.all()[:20]
+            data = PollSerializer(polls, many=True).data
+            return Response(data)
+
+
+
+    class PollDetail(APIView):
+        def get(self, request, pk):
+            poll = get_object_or_404(Poll, pk=pk)
+            data = PollSerializer(poll).data
+            return Response(data)
+
+
+And change your :code:`urls.py` to
+
+.. code-block:: python
+
+    from django.urls import path
+
+    from .apiviews import PollList, PollDetail
+
+    urlpatterns = [
+        path("polls/", PollList.as_view(), name="polls_list"),
+        path("polls/<int:pk>/", PollDetail.as_view(), name="polls_detail")
+    ]
 
 
+Using DRF generic views to simplify code
+-----------------------------------------
 
-Creating Views
-----------------
 
-Let us use generic views of Django Rest Framework for creating our views which will help us in code reusablity. The generic views alos aid us in building the API quickly and in mapping the database models.
