When I should check if request is is_ajax()?

I am a little bit confusing with docs. I can't understand real use case when I should check request to is_ajax()?

It does not make much sense in a view IMHO - if your project is well designed, you know which views are expected to be invoked via ajax (and exclusively via ajax - havin the same view called either directly or via ajax is sure design smell) and which are not -, but it can be very useful in middlewares when you want to take some action depending on the request's (and eventually response) headers.

Best use case of is_ajax() is if you want to send different data to the client depending on the type of the request.

For example, if the request is not ajax, you may want to render a full page. But if the request is ajax, you may want to only send a json response.

Example:

def my_view(request):
    if request.is_ajax():
        return <json data>
    else:
        return render(...)
