Rails路由的未初始化常量问题

Question

这是我的路线配置：

map.resources :services do |services|
  services.resources :capabilities do |capabilities|
    capabilities.resources :http_headers
  end
end

这是我的“佣金路线”输出：

当我去/ services / new时，我收到了这个错误：

NameError in ServicesController#new

uninitialized constant ServicesController::Services

是什么给出的？我怎样才能正常工作和路由？感谢。

Answer 1

ServicesController是否由模型服务备份？您是否在控制器中意外地将其作为服务引用？

Answer 2

这可能与您的路线没有任何关系; ServicesController中的new方法正在尝试使用不存在的名为Services的（类？常量？对象？）。
