Mongoid，在 mongoid-history 中设置自定义访问器字段 gem

Question

我正在将 mongoid-history gem 添加到我的项目中。

根据指南 in github，当我将 Userstamp 添加到我的跟踪器时，它会创建 created_by 字段，访问器名为 creator.

他们写到我可以通过 gem 配置重命名它。

如何重命名这个字段？

Answer 1

根据文档，Userstamp 是另一个 gem，名为 mongoid_userstamp。文档提供了通过配置文件或每个模型内部配置名称的示例代码：

config/mongoid_userstamp.rb:

# Default config (optional unless you want to customize the values)
Mongoid::Userstamp.config do |c|
  c.user_reader = :current_user
  c.created_name = :created_by
  c.updated_name = :updated_by
end

app/models/your_model.rb

# Example model class
class Product
  include Mongoid::Document
  include Mongoid::Userstamp

  # optional class-level config override
  # mongoid_userstamp user_model: 'MyUser',
  #                   created_name: :creator,
  #                   updated_name: :updater,
end

# Example user class
class MyUser
  include Mongoid::Document
  include Mongoid::Userstamp::User

  # optional class-level config override
  # mongoid_userstamp_user reader: :current_my_user
end

在Mongoid History中，你可以在HistoryTracker里面包含配置class，例如：

# app/models/history_tracker.rb
class HistoryTracker
  include Mongoid::History::Tracker
  include Mongoid::Userstamp
  # optional class-level config override
  mongoid_userstamp created_name: :updater,
                    updated_name: :another_updater,
end
