I'm upgrading an application to use the asset pipeline.
I've got the css assets compiling into an application css file but they not being found when I run the application in production mode with
RAILS_ENV=production bundle exec rails s
and I visit any page I get the correct output from the database but no styling and the log shows:
ActionController::RoutingError (No route matches [GET]
"/assets/default.scss-1a27c...f07c.css"):
Even though that file exists in public/assets
$ ls public/assets/def*
public/assets/default.scss-1a27c...f07c.css public/assets/default.scss.css
public/assets/default.scss-1a27c...f07c.css.gz public/assets/default.scss.css.gz
What do I need to change to get the server to find the asset file?
Same is happening for my other .css files. They get compiled into public/assets with finger prints but then are not found.
Page source is showing:
<link href="/assets/default.scss-1a27c...f07c.css"
media="screen" rel="stylesheet" type="text/css" />
The rails (haml) source is = stylesheet_link_tag 'default.scss.css'
public.assets
curently includes has the following files.
$ ls public/assets/def*
public/assets/default.scss-1a27c22229b7b522066181f27af4f07c.css
public/assets/default.scss-1a27c22229b7b522066181f27af4f07c.css.gz
public/assets/default.scss.css
public/assets/default.scss.css.gz
application.rb has
$ cat config/application.rb
require File.expand_path('../boot', __FILE__)

# If you precompile assets before deploying to production, use this line

module Linker
class Application < Rails::Application
config.encoding = "utf-8"
config.filter_parameters += [:password]
config.assets.enabled = true
config.assets.initialize_on_precompile = false # For Heroku
config.assets.version = '1.0'
end
end
config/environments/production
has:
$ cat config/environments/production.rb
Linker::Application.configure do
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
config.assets.precompile += ['default.scss.css','main.css', 'jquery-ui-1.8.22.custom.css']

config.assets.compress = true
config.assets.compile = false
config.assets.digest = true
config.log_level = :debug
config.i18n.fallbacks = true

end
This seems to be happening for all assets, e.g.

Rails by default doesn't serve assets under public
. See your production.rb
:
config.serve_static_assets = true
Change that to true and you're good to go. (Note: you don't want that to be true
in production, remember to change it back before deploying!)
See Configuring Rails Applications for details.
In rails 6, in the default production.rb
there should be a line
config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?
So run your server with
RAILS_SERVE_STATIC_FILES=true rails server -e production
or set config.public_file_server.enabled=true
in production.rb
. See answers below for rails 4 and 5.
