我有两个控制器

一个被定义为

class Admin::Businesses::DealsController < AdminController

它位于app/controllers/admin/businesses/deals_controller.rb

另一个

class Admin::DealsController < AdminController

位于app/controllers/admin/deals_controller.rb

一切都可以在开发环境中找到，但是当我推送到 heroku 并且应用程序在生产环境中加载时，它给了我这个错误

 /app/app/controllers/businesses/deals_controller.rb:1:in `<top (required)>': superclass mismatch for class DealsController (TypeError)

我的 routes.rb 中的相关行看起来像这样

namespace 'admin' do
    resources :deals do
    end
    resources :businesses do
      resources :deals, module: "businesses"
    end
 end

由于控制器名称相同，为什么它给我这个错误？还是超类不匹配？我怎样才能解决这个问题。我想要两个控制器用于交易，一个在 admin 下，另一个在 admin/businesses 下用于业务特定操作。

这是尝试使用 rails s -e production 在 prod 环境中本地运行应用程序时的完整堆栈跟踪

问题是admin您的路线中的命名空间与您admin的类层次结构中的模块冲突。有关导致该特定错误的原因的详细信息很复杂，但在http://code.dblock.org/warning-toplevel-constant-xyz-referenced-adminxyz中有更详细的解释

最简单的解决方案是将您admin的其中一个（可能是类名）重命名为其他任何名称。
