multiple filter example

actually you can have it even shorter with:

before_filter :authorize, :set_locale, :except => :login

two ways to disable single table inheritance

1. Don’t use the column name ‘type’

2. Or if the first is no option for you: Tell Rails to look for a not existing column like:

class MyModel < ActiveRecord::Base

  # disable STI
  inheritance_column = :_type_disabled
end  

alternative (working with 2.2.X)

ActionController::Base.relative_url_root
