安装生成器不会看到我定义的方法

Question

我正在尝试在另一个应用程序中使用我的引擎来测试安装生成器，但它似乎失败了。我已经很长时间没有使用我的安装生成器了，所以我不确定它什么时候坏了（或者它是否真正顺利地工作过）。我的项目是基于 radar/forem，所以我尝试借鉴了他们的很多代码（包括生成器）。

编辑：我的安装程序适用于引擎 test/dummy 但不适用于其他应用程序。为什么？

这是日志：

$ rails g mongoid_forums:install
What is your user class called? [User] 
What is the current_user helper called in your app? [current_user] 
Defining mongoid_forums_user method inside ApplicationController...
      insert  app/controllers/application_controller.rb
Adding mongoid_forums initializer (config/initializers/mongoid_forums.rb)...
      create  config/initializers/mongoid_forums.rb
(erb):5:in `template': undefined method `per_page' for MongoidForums:Module (NoMethodError)
The route is successfully added, however the initializer/mongoid_forums.rb is a blank file. The method is defined exactly how radar/forem does it, what could be the error?
