I made a basic rails app with a simple pages controller with an index function and when I load the page I get:

ActionView::Template::Error (application.css isn't precompiled):    2: <html>    3: <head>    4:   <title>Demo</title>    5:   <%= stylesheet_link_tag    "application" %>    6:   <%= javascript_include_tag "application" %>    7:   <%= csrf_meta_tags %>    8: </head>  app/views/layouts/application.html.erb:5:in `_app_views_layouts_application_htm

By default Rails assumes that you have your files precompiled in the production environment, if you want use live compiling (compile your assets during runtime) in production you must set theconfig.assets.compile to true.

# config/environm ents/production.rb

...config.assets.compile = true...

You can use this option to fallback to Sprockets when you are using precompiled assets but there are any missing precompiled files.

If config.assets.compile option is set to false and there are missing precompiled files you will get an "AssetNoPrecompiledError" indicating the name of the missing file.

Run bundle exec rake assets:precompile on your local code
Commit the changes and deploy to heroku
