Include Assets Only If They Exist

Question

In our current rails app, we are following certain patterns for including assets such as scripts and stylesheets.

Answer 1

To include an asset based on controller name

<% controller_asset = controller.controller_name %>
<%= stylesheet_link_tag controller_asset if YourApp::Application.assets.find_asset(controller_asset) %>

To include an asset based on controller name and action name (was useful for me)

<% action_asset = "#{controller.controller_name}/#{controller.action_name}" %>
<%= stylesheet_link_tag action_asset if YourApp::Application.assets.find_asset(action_asset) %>

And of course it'd be better not to leave this code as it is, but rather place it in a helper.
