Custom Flash Types in Edge Rails

gistfile1.rb

# Rails Edge: Custom Flash Types
#
#Rails just got some syntactic sugar for dealing with flash messages in
#your controllers and views.
#
#You can now declare the following in your controllers:
#

class ApplicationController
  add_flash_types :error, :warning
end


#And then you'll be able to use
 <%= error %> 
#in your views and 
redirect_to root_path, error: "message" 
#in your controllers.
#
#Commit message: [Added support add_flash_types](https://github.com/rails/rails/commit/238a4253bf229377b686bfcecc63dda2b59cff8f)
