我将我的rails 3.0应用程序升级到3.1（然后3.2希望它能解决这个问题 - 它没有做到）。自升级以来，如果我添加:controller和:action
%li
=link_to "foo",:controller => "utils", :action => 'my_controller_action'
这是我得到的堆栈跟踪：

路线和方法在那里（它在3.0中运行良好）。如果我对URL进行硬编码，它就可以工作。
当我调试代码时，我得到：lib / action_controller / metal / url_for.rb
module ActionController
module UrlFor
extend ActiveSupport::Concern
include AbstractController::UrlFor
def url_options
@_url_options ||= super.reverse_merge(
:host => request.host,
:port => request.optional_port,
:protocol => request.protocol,
:_path_segments => request.symbolized_path_parameters
).freeze
if _routes.equal?(env["action_dispatch.routes"])
@_url_options.dup.tap do |options|
options[:script_name] = request.script_name.dup
options.freeze
end
else
@_url_options
end
end
end
end
当我检查if _routes.equal?(env["action_dispatch.routes"])时，env是 false 而不是通常的路线数组......
有什么想法吗？

解决方案：我有一个
def env
...
end
在我的控制器中，从未在rails 3.0中给我一个问题。重命名以解决问题。
答案 0 :(得分：0)
我的控制器覆盖了env变量。我有：
def env
...
end
...在升级到3.2之前不会导致问题的控制器中。更改方法的名称修复了问题。谢谢@boulder指出我正确的方向！
