Rails assets not precompiling, css looks different in production
assets, css, ruby-on-rails, ruby-on-rails-4
Solution
In your `config/environments/production.rb` file, set:
`config.serve_static_assets = false` (currently it's set to true)
`config.assets.compile = true` (currently it's set to false)
This should solve your problem.
Let me explain what I am asking you to do.
- By setting `config.serve_static_assets = false`, we are telling rails server, don't add `ActionDispatch::Static` middleware, which is used to serve static assets.
Why not?
That's because in production environment, you are expected to run your application server (like puma) behind a web server (like Apache/Nginx), which is designed to serve static files (including assets) directly, without bothering to send the request to rails application server.
Since, you are not using any web server, we are turning it off.
- By setting `config.assets.compile = true`, we are telling rails to compile the requested asset at runtime. i.e. Look for the requested asset in `app/assets`, `vendor/assets`, `lib/assets` and serve it if found from any of these locations.
By default, `config.assets.compile` is `true` in development, `false` in production environment. Since, we are not using web server to serve static assets, we are asking rails to live compile our assets.
For further details refer to the asset pipeline documentation.
Problem
My rails app in dev mode works and looks exactly as I want it to, but in production it looks different on chrome and safari, in safari the logo images loads but not the font, in chrome the font loads but not the image plus the input fields are a little longer and mis-aligned in chrome but in dev mode it all looks great in chrome I been messing with this for a while and deleted the public/assets a few times a did ``` rake assets:precompile RAILS_ENV=production ``` with no success, the precompile goes through with no errors config/application.rb: ``` # Settings in config/environments/* take precedence over those specified here. # Application configuration should go into files in config/initializers # -- all .rb files in that directory are automatically loaded. config.assets.paths << "#{Rails.root}/assets/fonts" config.assets.paths << "#{Rails.root}/assets/images" config.assets.paths << Rails.root.join("app", "assets", "fonts") config.assets.precompile += %w( .svg .eot .woff .ttf ) # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone. # Run "rake -D time" for a list of tasks for finding time zone names.
