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

You can check for a header[X-Requested-With] to see if it is an AJAX request. Here is a good article on how to do it.

Here is an example:

if request.xhr?
  # respond to Ajax request
else
  # respond to normal request
end
