Mongoid 不保存设定值

Question

我的问题是，对于未自动设置的属性，我总是收到 nil 值。以下是一些示例：

2.3.1 :001 > t = Team.new(name: "team_1", code: "a123")
 => #<Team _id: 581b2f230640fd0cf4070a47, created_at: nil, updated_at: nil, code: nil, name: nil> 
2.3.1 :002 > t.save
 => true 
2.3.1 :003 > t
 => #<Team _id: 581b2f230640fd0cf4070a47, created_at: 2016-11-03 12:35:58 UTC, updated_at: 2016-11-03 12:35:58 UTC, code: nil, name: nil> 
2.3.1 :004 > t.name = "team_1"
 => "team_1" 
2.3.1 :005 > t
 => #<Team _id: 581b2f230640fd0cf4070a47, created_at: 2016-11-03 12:35:58 UTC, updated_at: 2016-11-03 12:35:58 UTC, code: nil, name: nil>

这是我在示例中使用的模型：

class Team
  include Mongoid::Document
  include Mongoid::Timestamps

  attr_accessor :name, :code, :owner_id, :learnin_object_ids, :active

  field :code, type: String
  field :name, type: String
end

我的 Gemfile：

source 'https://rubygems.org'

如何保存正确的数据？

Answer 1

问题是由 attr_accessor 引起的。删除后，将保存正确的数据。
