Rails 3.1 and jquery-ui assets

Question

This was asked in another question, but none of the solutions appear to work for me in 3.1rc1.

I\'m trying to use the new assets stuff in rails 3.1 - I have the file

Answer 1

It seems to me that a lot of confusion can be avoided by keeping these library assets out of assets/javascripts and assets/stylesheets dirs, where sprockets et al have some opinions about what should happen.

Say you've downloaded a customized jquery-ui zipfile from the themeroller. Try this:

1. unpack the zip file into an subdir of an assets dir, something like

   vendor/assets/jquery-ui-1.8.23.custom
   

2. in application.rb add:

   config.assets.paths << Rails.root.join('vendor', 'assets', 'jquery-ui-1.8.23.custom').to_s
   

3. add manifest files in the usual places:

   vendor/assets/javascripts/jquery-ui.js:

   //= require_tree ../jquery-ui-1.8.23.custom
   

   vendor/assets/stylesheets/jquery-ui.css:

   *= require_tree ../jquery-ui.1.8.23.custom
   

4. in config/environments/production.rb, add (referring to manifest filenames):

   config.assets.precompile += %w(jquery-ui.js jquery-ui.css)
   

5. in views:

   <%= stylesheet_link_tag 'jquery-ui' %>
   <%= javascript_include_tag 'jquery-ui' %>
