unable to find jquery.ui.all for rails mountable engine using .gemspec about jquery-ui-rails HOT 9 CLOSED

Curious.

The only technical difference between the css and js file is, vendor/assets/javascripts/jquery.ui.all.js is a plain JS file, while vendor/assets/stylesheets/jquery.ui.all.css.erb is preprocessed with Erb. Could that have something to do with it?

I've got the same problem. Also occuring when trying to load specific css, like the datepicker example from the README.

Update: It seems like this is more of an engine/asset pipeline issue. If I add jquery-ui-rails to the main app's Gemfile, everything works - but if I add it to the engine's Gemfile (or gemspec), the asset paths to the jquery-ui-rails gem are not added to the main app.

I think I've got it: In an engine, when using a gemspec, you need to require your dependencies, otherwise those dependencies' asset paths aren't added to the host app. I.e.:

module MyEngine
  class Engine < Rails::Engine
    require 'jquery-ui-rails'
  end
end

• 1. I had the same problem and @MGPalmer's solution worked for me too.

Interestingly this only affected the css files. The javascript was working fine without this fix.

Very good (and very curious). I don't think this is something that needs fixing in jquery-ui-rails, is it? I'll go ahead and close this then.

Am still facing this issue, nothing worked for me so far :(

its indeed nothing to do with jquery-rails, as if I am commenting out @import 'jquery.ui.autocomplete'; I am getting similar error next for @import 'font-awesome';

Am using rails 4.0.9 with both main app and engine. my engine works fine with main app, but I am unable to rspec dummy app due to this error
