Model虚拟字段

经常我们会用到一些有数据库中多个字段组合而成的信息，如姓名（姓+ 名），地址（省+市+区+街道）.

class User < ActiveRecord::Base
  # Getter
  def full_name
    [first_name, last_name].join(' ')
  end

  # Setter
  def full_name=(name)
    split = name.split(' ', 2)
    self.first_name = split.first
    self.last_name = split.last
  end
end
