Rails 4: assets not loading in production
I'm trying to put my app into production and image and css asset paths aren't working.
Here's what I'm currently doing:
<%= stylesheet_link_tag "styles", media: "all", "data-turbolinks-track" => true %> RAILS_ENV=production bundle exec rake assets:precompile and it succeeds and I see the fingerprinted files in the public/assets directory. When I browse to my site, I get a 404 not found error for mysite.com/stylesheets/styles.css .
What am I doing wrong?
Update: In my layout, it looks like this:
<%= stylesheet_link_tag "bootstrap.min", media: "all", "data-turbolinks-track" => true %>
<%= stylesheet_link_tag "styles", media: "all", "data-turbolinks-track" => true %>
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
The generate source is this:
<link data-turbolinks-track="true" href="/stylesheets/bootstrap.min.css" media="all" rel="stylesheet" />
<link data-turbolinks-track="true" href="/stylesheets/styles.css" media="all" rel="stylesheet" />
<script data-turbolinks-track="true" src="/assets/application-0c647c942c6eff10ad92f1f2b0c64efe.js"></script>
Looks like Rails is not properly looking for the compiled css files. But it's very confusing why it's working correctly for javascripts (notice the /assets/****.js path).
In rails 4 you need to make the changes below:
config.assets.compile = true
config.assets.precompile = ['*.js', '*.css', '*.css.erb']
This works with me. use following command to pre-compile assets
RAILS_ENV=production bundle exec rake assets:precompile
Best of luck!
I just had the same problem and found this setting in config/environments/production.rb:
# Rails 4:
config.serve_static_assets = false
# Or for Rails 5:
config.public_file_server.enabled = false
Changing it to true got it working. It seems by default Rails expects you to have configured your front-end webserver to handle requests for files out of the public folder instead of proxying them to the Rails app. Perhaps you've done this for your javascript files but not your CSS stylesheets?
(See Rails 5 documentation). As noted in comments, with Rails 5 you may just set the RAILS_SERVE_STATIC_FILES environment variable, since the default setting is config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present? .
In /config/environments/production.rb I had to add this:
Rails.application.config.assets.precompile += %w( *.js ^[^_]*.css *.css.erb )
The .js was getting precompiled already, but I added it anyway. The .css and .css.erb apparently don't happen automatically. The ^[^_] excludes partials from being compiled -- it's a regexp.
It's a little frustrating that the docs clearly state that asset pipeline IS enabled by default but doesn't clarify the fact that only applies to javascripts.
