To solve this problem, add "XMLHttpRequest" to your headers like this.

# app.js

headers: {
    "X-Requested-With": "XMLHttpRequest"
}

or like this:

fetch('YourURL', { method: "POST",headers: { "X-Requested-With": "XMLHttpRequest" }, body: form})

CodePudding user response：

request.is_ajax is deprecated since django 3.1 and has been removed since django 4. You can use

if request.headers.get('x-requested-with') == 'XMLHttpRequest':

instead of

if request.is_ajax:
