How to programmatically call a Django Rest Framework view within another view?

Question

I have the following generic class based views built with Django Rest framework (DRF)

class ExampleDetail(generics.RetrieveUpdateDestroyAPIView):
    queryse         


        

Answer 1

As of Django 2.2 and DRF 3.9.2 I am able to get response using below code.

response = UserItemsApiView.as_view()(request=request._request).data

Above example solves below issues:

• The request argument must be an instance of django.http.HttpRequest, not rest_framework.request.Request
• Instead of content, using data attribute gave me result from that view.

Answer 2

I found the solution for this in the documentation... https://docs.djangoproject.com/en/1.7/topics/class-based-views/mixins/

Hint is from their example here:

class AuthorDetail(View):

    def get(self, request, *args, **kwargs):
        view = AuthorDisplay.as_view()
        return view(request, *args, **kwargs)

    def post(self, request, *args, **kwargs):
        view = AuthorInterest.as_view()
        return view(request, *args, **kwargs)

Answer 3

If I'm understanding correctly, you need to get the result from view B, while inside view A.

Using the requests/urllib2 and json libraries should solve your problem (as specified in this answer).

To get the URL, you can use a combination of request.get_absolute_uri() and/or request.get_host() and django.core.urlresolvers.reverse.

Answer 4

I didn't tried it, but I think the following should work.

• Server side:

Call the DRF and poing by url.open or request

as this answer suggest

Example:

import requests
from django.shortcuts import render


def home(request):
   # get the list of todos
   response = 
    requests.get('https://jsonplaceholder.typicode.com/todos/')
   # transfor the response to json objects
   todos = response.json()
   return render(request, "main_app/home.html", {"todos": todos})

Complete example

• Client side:

You can call the DRF and point by ajax request from any other view.

Answer 5

html_from_view = ExampleDetail.as_view({'get': 'list'})(request).content

OR

html_from_view = ExampleDetail.as_view({'get': 'retrieve'})(request, pk=my_id).render().content
