Javascript File Path to be included via content_for in Ruby on Rails

Question

I have read that if you want to include a javascript file specific to your view you can use content_for and yield functions of ruby. Following is sample code to do it. I want to know what is the path where it will look for forms.js.

<% content_for :javascript_includes do %>
  <%= javascript_include_tag "forms.js" %>
<% end %>

Answer 1

TL;DR Using content_for has no implications on the lookup path for assets.

Rails will look in multiple places, as is does for all assets. In case of forms.js it will look for

1. app/assets/javascripts/forms.js
2. lib/assets/javascripts/forms.js
3. vendor/assets/javascripts/forms.js

(If not found in one of these locations, it will proceed looking in all required gems, which provide a Rails Engine. Within these gems it will again look at the locations given above.)
