jquery post get missing template in rails

Question

in my jquery post I have code like this

function checkBill(trs_id, bill_id){
    $.ajax({
      type: 'POST',
      url: "/check_bill",
      data: {bill_id: bill_id, transaction_id: trs_id},
      headers: {
        'X-CSRF-Token': '<%= form_authenticity_token.to_s %>'
      },
      dataType: 'script'
    });
  }

in my controller successfully get params for jquery post, but I get error missing template in my log? I don't know why? I guess jquery post not need template

Are you sure you need your CSRF token in your jquery? It's alreay outputted in the meta code of your webpage — Richard Peck, Nov 12 '13 at 09:17

The missing template is basically a lack of check_bill.js.erb in your views folder

Views & Ajax

When your server receives a request (either HTTP or Ajax), it will process it by running the action & rendering the required view

Rails allows you to render HTML & JS views, which come in the form action_name.html.erb or action_name.js.erb. If you're sending a JS request, Rails therefore tries to render the .js.erb

Returning JS Requests

If you want to return JS requests, you'll need to use the code the other answers have stated (respond_to):

#app/controllers/your_controller.rb
def check_bill
    respond_to do |format|
        format.js { render :nothing => true } 
    end
end

The difference is what you want to return to Ajax. I'll update my answer if you let us know what kind of response you're expecting

you should give instructions to your controller action to respond with a js. Like this:

 respond_to do |format|
   format.js {render :text => 'ok'}
 end

otherwise it will try to reply with an html view
