Uninitialized constant problem for Rails routes
提问by Laran Evans
Here's my route configuration:
这是我的路由配置：
map.resources :services do |services|
services.resources :capabilities do |capabilities|
capabilities.resources :http_headers
end
end
Here's my "rake routes" output:
这是我的“耙路线”输出：

When I go to /services/new though, I get this error:
但是，当我转到 /services/new 时，出现此错误：
NameError in ServicesController#new uninitialized constant ServicesController::Services
What gives? How can I get things working and routed correctly? Thanks.
是什么赋予了？我怎样才能让事情正常工作并正确路由？谢谢。

Is ServicesController backed up by a model Service? Did you accidentally reference it as Services in your controller?
ServicesController 是否由模型服务支持？您是否不小心在控制器中将其引用为服务？
回答by Jim Puls
This probably doesn't have anything to do with your routes; your newmethod in ServicesController is trying to use a (class? constant? object?) named Servicesthat doesn't exist.
这可能与您的路线无关；您new在 ServicesController 中的方法试图使用一个（类？常量？对象？）命名的Services不存在。
