Call specific method in Class based api view django - django

Question

i am new to DRF, and implemneting class based views and a sample example is this i have tried
#api_view(['GET', 'POST'])
class ProductList(APIView):
print "inside"
def get_user_products(self, request, user_id, format=None):
products = Product.objects.all(user_id=user_id)
serializer = ProductSerializer(products, many=True)
return Response(serializer.data)
def get_seller_products(self, request, seller_id, format=None):
products = Product.objects.filter(seller_id=seller_id)
serializer = ProductSerializer(products, many=True)
return Response(serializer.data)
def post(self, request, user_id, seller_id, format=None):
serializer = ProductSerializer(data=request.DATA, context={'request':request})
if serializer.is_valid():
serializer.object.user = User.objects.get(id=user_id)
serializer.object.seller = Seller.objects.get(id=seller_id)
serializer.save()
return Response(serializer.data, status=status.HTTP_201_CREATED)
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
i this class for my product apis , but i am not sure how can i access individual methods to access the corresponding result, like how can i hit get_user_products or get_seller_products
Right now when i call this api like this http://localhost:8000/products
as GET method this class executed and it prints "inside" as you can see, but how do i call the methods inside it
Here is the url.py for this app
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^', include(router.urls)),
url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
url(r'^login$', 'userapp.views.login_user', name="login"),
url(r'^products$', 'productapp.views.ProductList', name="product-list"),
]

You're not supposed to use the api_view decorator to decorate class-based views; you use api_view with function-based views.
If you want to use a class-based view, like the one in your example, remove the print statement, and the api_view decorator, and include the view in your urlconf by importing the view, and using ProductList.as_view(), as shown in the tutorial. In your case, the urlconf might look like this:
from productapp.views import ProductList
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^', include(router.urls)),
url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
url(r'^login$', 'userapp.views.login_user', name="login"),
url(r'^products$', ProductList.as_view(), name="product-list"),
]
Also, keep in mind, that using strings containing import paths for your views in urlpatterns is deprecated, and support for this will be removed in an upcoming version of Django. Instead, import all your views inside your urlconf, and use the view functions directly, for example:
from productapp.views import ProductList
from userapp.views import login_user
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^', include(router.urls)),
url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
url(r'^login$', login_user, name="login"),
url(r'^products$', ProductList.as_view(), name="product-list"),
]
