How to include certain files?

Question

Ruby on Rails

Rails has an assets folder. there lies scripts and styles. For each new controller, a new coffescript and a new scss are created.
Is it possible to make sure that if we use a specific controller, then application.js and the script of this particular controller are loaded?
And then I get a lot of files already and they are loaded on all pages. And I need to load certain scripts and application.js in certain pages, how can I implement this?

Answer 1

<%= javascript_include_tag params[:controller] %>

Answer 2

You can do this
in the layout, write
A on the connect page:

<% content_for :after_js do %>
  <%= javascript_include_tag 'pages/users/index' %>
<% end %>

Also forget to exclude the file from application.js
AND add it to config/initializers/assets.rb

Rails.application.config.assets.precompile += ['pages/users/index.js']
