ruby on rails只加载1个css＆js文件

Question

I am new to ruby on rails and whenever i create and access a controller i can see it loads a new css & js file with name as the name of the controller...

How can i make it load only 1 css and js file called style.css and site.js for example?

what is the purpose of having multiple js & css files whenever i access a contrller?

if i go to application.html.erb and change

  <%= stylesheet_link_tag    "application", :media => "all" %>
  <%= javascript_include_tag "application" %>

to

  <%= stylesheet_link_tag("application") %>
  <%= javascript_include_tag("application") %>

it doesnt seem to help

Answer 1

I dont know which Rails version you are using, but assuming it is the recent one, then Rails are using Assets Pipeline, to merge multiple files and serve all css / javascript files compressed / merged.

You can learn more about it at http://guides.rubyonrails.org/asset_pipeline.html

Basically what you do is, you reference one file 'application' (css or js) and inside this file, you customize which files it should include.

Answer 2

The code:

<%= stylesheet_link_tag    "application", :media => "all" %>
<%= javascript_include_tag "application" %>

will include all .css and .js files available in assets/javascripts/ and assets/stylesheets/ . So, if you want to include only the style.css and site.js just remove everything else.

Your assets/javascripts/ should have only the application.js and site.js .

And your assets/stylesheets/ should have the application.css and style.css .

EDIT

`application.js and application.css are part of the asset pipeline .

You can disable it if you want by adding this line in your application.rb

config.assets.enabled = false

You can also change the application.html.erb to include only your style.css and site.js :

<%= stylesheet_link_tag    "style", :media => "all" %>
<%= javascript_include_tag "site" %>

I hope it helps...

Try using :cache => 'cache-display'

<%= stylesheet_link_tag :all, :cache => 'cache/display' %>
<%= javascript_include_tag :all, :cache => 'cache/display' %>
