覆盖Mongoid模型的setter和getter

Question

有没有办法在Mongoid中覆盖模型的setter或getter？就像是:

class Project
  include Mongoid::Document
  field :name, :type => String
  field :num_users, type: Integer, default: 0
  key :name
  has_and_belongs_to_many :users, class_name: "User", inverse_of: :projects

  # This will not work
  def name=(projectname)
    @name = projectname.capitalize
  end
end

在name不使用虚拟字段的情况下可以覆盖方法？

Answer 1

更好用

def name=(projectname)
  super(projectname.capitalize)
end

方法

self[:name] = projectname.capitalize

可能是危险的,因为它会导致超载会导致无休止的递归

Answer 2

def name=(projectname)
  self[:name] = projectname.capitalize
end
