  1. POHow do I get jQuery Mobile precompiled for Rails 3 production?
    text
    copied!<p>I'm trying to deploy a Rails 3 app which includes jQuery Mobile. It works fine in development, and I understand that it needs to precompile the JS and CSS for production. I'm getting the following error:</p> <pre><code>Started GET "/orders/mobile" for 127.0.0.1 at Wed Jun 06 14:22:40 -0400 2012 Processing by OrdersController#mobile as HTML Rendered orders/mobile.html.erb within layouts/mobile (642.9ms) Completed 500 Internal Server Error in 1122ms ActionView::Template::Error (jquery.mobile isn't precompiled): 5: &lt;head&gt; 6: &lt;meta http-equiv="content-type" content="text/html;charset=UTF-8" /&gt; 7: &lt;title&gt;Company Orders&lt;/title&gt; 8: &lt;%= stylesheet_link_tag 'jquery.mobile' %&gt; 9: &lt;%= stylesheet_link_tag 'jquery.mobile.structure' %&gt; 10: &lt;%= stylesheet_link_tag 'jquery.mobile.theme' %&gt; 11: &lt;%= stylesheet_link_tag 'http://fonts.googleapis.com/css?family=Ubuntu' %&gt; app/views/layouts/mobile.html.erb:8:in `_app_views_layouts_mobile_html_erb__605278794_69818059003840' app/controllers/orders_controller.rb:330:in `mobile' app/controllers/orders_controller.rb:329:in `mobile' </code></pre> <p>I've read the <a href="http://guides.rubyonrails.org/asset_pipeline.html#manifest-files-and-directives" rel="nofollow">usual</a> stuff, but there are so many things wrong here, I hardly know where to start:</p> <ol> <li>I had the JQM stuff in app/assets, but have since moved them to vendor/assets. They get seen by the precompiler -- I know because it will complain about them on various tries -- but they never seem to get precompiled (in either location).</li> <li>I've tried <code>*= require_tree ../../../vendor/assets/stylesheets</code> in application.css. I don't really want it included in every page hit, so I'd like to include it in the layout, but I'm just trying to get it precompiled somehow.</li> <li>I've tried <code>*= require jquery.mobile[[.css].erb]</code> in application.css.</li> <li>I've tried <code>config.assets.precompile += %w( [[./]vendor/assets/stylesheets/]jquery.mobile.* )</code> in config/environments/production.rb.</li> </ol> <p>As a last-ditch effort, I've removed the ".erb" from jquery.mobile.css.erb, and removed the <code>&lt;% asset_data_uri %&gt;</code> tags to see if it would compile. It passes the <code>rake assets:precompile</code> command, but <em>still</em> gives me the same error.</p> <p>I don't want to turn off precompiling for JQM; I <em>want</em> it to work. (I really need to speed this page up.) However, I can't find any guide on how to get JQM elegantly inserted into a Rails 3 app (with precompiling), and I've exhausted every avenue I can think of in trial and error. Surely someone has done this and knows the right way to go about it.</p>
