Question

所以我在我的项目中有多个模型，其中许多模型具有激活和停用功能，我使用AASM管理

aasm column: 'status' do
  state :active, :initial => true
  state :inactive

  event :deactivate do
    transitions :from => :active, :to => :inactive
  end

  event :activate do
    transitions :from => :inactive, :to => :active
  end
end

我想避免重复此代码，它有4个不同的模型，我可能不会再添加任何状态。

提前致谢

您可以使用此部件创建模块并将其放入models/concerns/或lib/文件夹（或其他地方，只需确保已将其上传）：

  module ActivateDeactivateStatuses
    extend ActiveSupport::Concern

    included do
      aasm column: 'status' do
        state :active, :initial => true
        state :inactive

        event :deactivate do
          transitions :from => :active, :to => :inactive
        end

        event :activate do
          transitions :from => :inactive, :to => :active
        end
      end
    end
  end

并在你的模特中：

  include ActivateDeactivateStatuses

如何避免使用AASM重复代码？
