将所有JavaScript加载到资产JavaScript下是否很好？

Question

I wonder what's practice is better to load Javascripts in Rails app.

Because every page will load all the js files under asset folder.

But most of coffescripts are only apply on their own controller.

So to require_tree . seems a bad idea, here.

So I need to include corresponding coffee script for each view ?

It also seems a bad idea, and easily to cause maintain problem.

Any idea ? Thanks

Application.js

//= require_tree .

By default Rails handles assets at the controller level and will automatically include the appropriate assets as long as they are in the right file, which corresponds to a controller. In this case it works correctly with the //= require_tree . directive.

If you prefer, you can also include controller specific assets manually in layouts or views like so: <%= javascript_include_tag params[:controller] %> or <%= stylesheet_link_tag params[:controller] %> . In this case your require directives should not have //= require_tree . . Remember that you will have to specify any files not in your require directive for pre-compilation in production.

For more see the Rails documentation at http://guides.rubyonrails.org/asset_pipeline.html , under '2.1 Controller Specific Assets'.
