Rails detect if request was AJAX

Question

In my action I wish to only respond with processing if it was called from an AJAX request. How do I check?

I want to do something like this:

def acti         


        

Answer 1

If you're using :remote => true in your links or forms, you'd do:

respond_to do |format|
  format.js { #Do some stuff }

You can also check before the respond_to block by calling request.xhr?.
