How to determine in django that an ajax request is an XMLHttpRequest?

Question

Django

How to determine in a view that the request came using ajax, or rather, through javascript XMLHttpRequest or fetch?
Since I use javascript, the if request.is_ajax() check in django does not work, because false.

Answer 1

Since the ajax request was made on javascript, and not on jQuery, it was necessary to manually add the necessary attribute to the request header so that django would define request.is_ajax()

fetch('http://127.0.0.1:8000/main/katalog/5/', {
              method: 'GET',
              headers: {'X-Requested-With': 'XMLHttpRequest'}});

Answer 2

Request Header must contain
X-Requested-With:XMLHttpRequest
