Defining Enum Columns

Each enum_column has a name and a set of attributes. The name is used to guess the class of the object by default, but it's possible to explicitly specify it:

  class User < ActiveRecord::Base
    enum_column :platform, [:iphone, :windows_mobile, :android]
    enum_column :state, [:on, :off, :waiting]
  end

Example

  @user = User.new
  @user.platform = :iphone
  @user.platform
=>:iphone
  @user[:platform]
=> 0
