Home » Rails 3.1 Upgrade Notes

If you use conditional comments for browser specific stylesheets you need to add those file names to config.assets.precompile array in production.rb file like;

config.assets.precompile += ['admin.js', 'admin.css', 'ie7.css', 'ie.css']

To auto compile assets after deployment with Capistrano, add this to Capfile;

load 'deploy/assets'

Use model_instance.errors[:base] << “Msg” instead of deprecated model_instance.errors.add_to_base(“Msg”)
