来自引擎的 Monkey 补丁 ActiveAdmin class

Question

我有一个engine that will be installed over an application that uses Active Admin...

安装 Active Admin 后，我需要运行我的引擎安装程序。这将创建一个文件猴子修补活动管理员 class。

文件看起来像这样...

module ActiveAdmin
  module Devise
    # things I need to add...
  end
end

所以，问题是：我需要把这个文件放在哪里，为什么？

Answer 1

我用了Railtie'sinitializer方法。

my_engine/lib/admin_invitable/engine.rb

module MyEngine
  class Engine < ::Rails::Engine
    isolate_namespace MyEngine
    initializer "ativeadmin_invitable_patch" do |app|
      require_relative "activeadmin_invitable_patch"
    end
  end
end

my_engine/lib/admin_invitable/activeadmin_invitable_patch.rb

module ActiveAdmin
  module Devise
    # bla bla
  end
end
