How to call a class based generic API view from a custom function based view

I am having some problems and doubts about how to call my own API within my app.

So I have an API to which I can send data. What I want to do in a different view is calling this sent data so I can visualize it in a template.

First I was trying to call the API with the library requests inside of my view. Even though that works I am having problems with authentication. So I was thinking I could call my class based API view from my custom function based view.

But I don't know if that is possible, nor do I know if that is recommendable. I was also thinking that it might be better to do that with javascript? I don't know.... So my question is twofold:

a) What is the best practice to call an API view/get API data from my own app so that I can manipulate and visualize it

b) If this is good practice, how can I call my class based generic API view from my custom function based view?

Here is what I am trying so far: 

my generic view

class BuildingGroupRetrieveAPIView(RetrieveAPIView):
    """Retrieve detail view API.

    Display all information on a single BuildingGroup object with a specific ID.

    """

    authentication_classes = [JSONWebTokenAuthentication, SessionAuthentication, BasicAuthentication]
    serializer_class = BuildingGroupSerializer
    queryset = BuildingGroup.objects.all()

my function based view with which I try to call it:

def visualize_buildings(request, id):
    returned_view = BuildingGroupRetrieveAPIView.as_view()
    return returned_view



my url

    path('data/<int:pk>/', BuildingGroupRetrieveAPIView.as_view(),
         name="detail_buildings_api"),

When I call my class based view I get AttributeError: 'function' object has no attribute 'get'

Help is very much appreciated! Thanks in advance!

Correct way:

from django.url import reverse, resolve

def get_view_func(name_of_your_view):
    return resolve(reverse(name_of_your_view)).func

# if your are in a drf view:
get_view_func()(request._request)

# if you are in normal django view:
get_view_func()(request)

What you can do if you want is to call your CBV after its declaration inside its file for the sake of easiness when declaring its URL.

views.py

class BuildingGroupRetrieveAPIView(RetrieveAPIView):
    .....


visualize_buildings = BuildingGroupRetrieveAPIView.as_view()

Then on your URLs, you use that name.

urls.py

from . import views


path('data/<int:pk>/', views.visualize_buildings, name="detail_buildings_api"),
