我最近一直在尝试将我的应用程序从 Rails 2.3.8 升级到新发布的 Rails 3。
在修复了一些 Rails 3 RubyAMF 之后似乎不起作用：
>>>>>>>> RubyAMF >>>>>>>>> #<RubyAMF::Actions::PrepareAction:0x1649924> took: 0.00017 secs
The action '#<ActionDispatch::Request:0x15c0cf0>' could not be found for DaysController
/Users/tammam56/.rvm/gems/ruby-1.9.2-p0/gems/actionpack-3.0.0/lib/abstract_controller/base.rb:114:in `process'
/Users/tammam56/.rvm/gems/ruby-1.9.2-p0/gems/actionpack-3.0.0/lib/abstract_controller/rendering.rb:40:in `process'
它似乎无法找到合适的控制器。可能与 Rails 3 路由器的新变化有关。您知道如何寻找问题的根本原因和/或尝试解决问题吗？
我正在从发生这种情况的 RubyAMF 粘贴代码（异常发生在以下行：@service.process(req, res)）：
#invoke the service call

begin
# RequestStore.available_services[@amfbody.service_class_name] ||=
@service = @amfbody.service_class_name.constantize.new #handle on service
