Ruby on rails 4 activerecord userstamp gem不工作

我试图将rails 3.x更新为4.2.x，并试图用activerecord userstamp替换userstamp gem，以存储创建者和更新者ID

我遵循了github中activerecord userstamp gem提供的所有步骤，并正确配置了gem

   ActiveRecord::Userstamp.configure do |config|
     # config.default_stamper = 'User'
     # config.creator_attribute = :creator_id
     # config.updater_attribute = :updater_id
     config.deleter_attribute = nil
   end

在我重置数据库并执行迁移之后

但我的模式仍然没有更新为creator\u id、updater\u id

      t.integer  "created_by", limit: 4
      t.integer  "updated_by", limit: 4

在my model user.rb中

     class User < ActiveRecord::Base
      model_stamper
     end

任何人都可以为您的解决方案提供帮助吗？

Activerecord userstamp在我运行迁移时加载MigrationHelper失败。我通过将迁移助手添加到repo中并在迁移文件中使用此助手方法解决了此问题

helper/activerecorduserstamp.rb

module activeRecorduserstamp

  module ActiveRecord::Userstamp::MigrationHelper
  extend ActiveSupport::Concern

   def userstamps(*args)
      config = ActiveRecord::Userstamp.config
      column(config.creator_attribute, :integer, *args)
      column(config.updater_attribute, :integer, *args)
      column(config.deleter_attribute, :integer, *args) if config.deleter_attribute.present?
   end
 end

  ActiveRecord::ConnectionAdapters::TableDefinition.class_eval do
    include ActiveRecord::Userstamp::MigrationHelper
  end
end

在我的迁移文件中，我将该helper方法包括为

db/migration/yyy.rd

include activeRecorduserstamp
class YYY < ActiveRecord::Migration
    def change
      change_table :YYY do |t|
      t.userstamps
    end

包含activeRecorduserstamp
类YYY

将助手方法添加到迁移文件后，Activerecord Userstamp工作得很好

提及

module activeRecorduserstamp

  module ActiveRecord::Userstamp::MigrationHelper
  extend ActiveSupport::Concern

   def userstamps(*args)
      config = ActiveRecord::Userstamp.config
      column(config.creator_attribute, :integer, *args)
      column(config.updater_attribute, :integer, *args)
      column(config.deleter_attribute, :integer, *args) if config.deleter_attribute.present?
   end
 end

  ActiveRecord::ConnectionAdapters::TableDefinition.class_eval do
    include ActiveRecord::Userstamp::MigrationHelper
  end
end

include activeRecorduserstamp
class YYY < ActiveRecord::Migration
    def change
      change_table :YYY do |t|
      t.userstamps
    end
