Rails 3.0.0 now has a release candidate. These are the changes I made to a new application I am working on to clear up any deprecation warnings.
Gemfile
gem ‘rails’, ‘3.0.0.rc’
gem ‘haml’, ‘3.0.14′
Obviously you have to tell your application to use the 3.0.0.rc. Also, it seems as if haml 3.0.13, which we were previously using, had some incompatible changes with Rails 3.0.0.rc
Rakefile
Change:
Rails::Application.load_tasks
to:
YourApplicationName::Application.load_tasks
config/environments/test.rb
Add:
config.active_support.deprecation = :stderr
config/routes.rb
Change:
YourApplicationName::Application.routes.draw do |map|
to:
YourApplicationName::Application.routes.draw do
