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

I like using before_action filters. They are especially nice when you need the same filter/authorization for multiple actions.

class MyController < AuthController
  before_action :require_xhr_request, only: [:action, :action_2]

  def action
    @model = Model.find(params[:id])
  end

  def action_2
    # load resource(s)
  end

  private

  def require_xhr_request
    redirect_to(root_url) unless request.xhr?
  end
end
