Tip #1: Don't do this
Dev
$ rails s
http://localhost:3000
Deploy to Prod
Tip #2:
Test Locally in Prod
It really is that important!
Local Prod
$ rails s -e production
http://localhost:3000
$ RAILS_ENV=production rails s
Trick #1:
Get Local Prod working
Differences
Dev
Prod
conf../env../development.rb
config.assets.compile = true
conf../env../production.rb
config.assets.compile = false
Compiles on the fly
conf../env../development.rb
config.assets.compile = true
Assumes precompilation
$ git checkout -b test-prod
$ RAILS_ENV=production bundle exec rake assets:precompile
$ rails s -e production
What happened?
config/environment/production.rb
config.serve_static_assets = true
TO THE RESCUE!
$ rails s -e production
BOOM
Trick #2:
CSS and Images
I really don't like you, CSS...
background-image: url(“/assets/pic.jpg”);
background-image: url(<%= asset_path 'pic.jpg' %>);
background-image: image-url("pic.jpg");
background: image-path("pic.jpg");
Tip #3:
For Rails 3.2.x users
gem 'turbo-sprocket-rails'
