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
所有功能都可以在开发环境中找到但是当我推送到heroku并且应用程序加载到生产环境中时它会给我这个错误
/app/app/controllers/businesses/deals_controller.rb:1:in `<top (required)>': superclass mismatch for class DealsController (TypeError)
来自我的routes.rb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
由于控制器的名称相同，为什么它会给我这个错误？还是超级不匹配？我怎样才能解决这个问题。我希望两个控制器用于管理下的一个交易，另一个管理/业务下用于业务特定操作。
尝试在prod env中使用本地运行应用程序时，这是完整的堆栈跟踪 rails s -e production

问题是您的路由中的admin命名空间与您的类层次结构中的admin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
最简单的解决方案是将您的admin之一（可能是类名）重命名为其他任何内容。
