Rails dynamic form remote true controller not responding

Question

I am trying to establish a dynamic form on a contact's page. I would like on this page to be a link that says "add an email address" and then when I click on it, a form appears to enter email address.

So I used a link_to with remote true :

  = link_to "Add an email", add_email_path, id:'link-remote-link', remote: true

In my controller i specified :

  def add_email
    render layout: false
  end 

But when I receive my response with listening on ajax:sucess, layout is still their in the variable. But I just want the form add_email.html.haml

In order to try to know if the code in my controller was executed, I tryed to put a creation of an object in it. Fact is that it was never created.

Never the less, rails console writes "Processing by ContactsController#add_email as JS "

So...why is it not executed ?

Thank you :)

Layout

We set the layout in the application_controller to manage the ajax responses:

#app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
   layout Proc.new { |controller| !controller.request.xhr? }
end

You may wish to try this - to see if it's the call in your controller which is rendering the layout.

Personally, I think your layout: false call is being overridden with some other element / part of your controller. I'd recommend checking to make sure this is the case

Controller

As you've stated, the case may be that your controller isn't being called, or processed correctly.

This could be caused by a number of issues, most notably from having incorrect routes, or some other dependency preventing the method from firing properly.

To clarify, I would make sure I have the following set up:

#config/routes.rb
resources :contacts do
   get :add_email, on: :collection
end

#app/controllers/contacts_controller.rb
class ContactsController < ApplicationController
   def add_email
      ...
   end
end
