Rails3 / ruby gem 中是否有一种方法可以将状态代码映射到消息？

例如，

200 => Found
403 => Not authorized
404 => Not found

我猜测 Rails 3 已经具有此功能，因为您可以将哈希传递给 render :status =>; :not_found，我只是找不到以其他方式执行此操作的方法。如果没有，有人知道可以做到这一点的宝石吗？

Such as

200 => Found
403 => Not authorized
404 => Not found

I'm guessing Rails 3 already has this functionality as you can pass a hash to render :status => :not_found, I just can't find the method to do it the other way. If not does anyone know of a gem which can do this?

irb(main):001:0> Rack::Utils::HTTP_STATUS_CODES[200]
=> "OK"
irb(main):002:0> Rack::Utils::HTTP_STATUS_CODES[403]
=> "Forbidden"
irb(main):003:0> Rack::Utils::HTTP_STATUS_CODES[404]
=> "Not Found"

或者

irb(main):004:0> Rack::Utils.status_code(:ok)
=> 200
irb(main):005:0> Rack::Utils.status_code(:forbidden)
=> 403
irb(main):006:0> Rack::Utils.status_code(:not_found)
=> 404

irb(main):001:0> Rack::Utils::HTTP_STATUS_CODES[200]
=> "OK"
irb(main):002:0> Rack::Utils::HTTP_STATUS_CODES[403]
=> "Forbidden"
irb(main):003:0> Rack::Utils::HTTP_STATUS_CODES[404]
=> "Not Found"

irb(main):004:0> Rack::Utils.status_code(:ok)
=> 200
irb(main):005:0> Rack::Utils.status_code(:forbidden)
=> 403
irb(main):006:0> Rack::Utils.status_code(:not_found)
=> 404
