覆盖Mongoid模型的设置者和获取者 [英] Override a Mongoid model's setters and getters

问题描述

是否有一种方法可以覆盖Mongoid中的模型的setter或getter?像这样:

Is there a way to override a setter or getter for a model in Mongoid? Something like:

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

name方法可以在不使用虚拟字段的情况下被覆盖吗?

where the name method can be overwritten without using virtual fields?

推荐答案

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