重新加载路由后 ActionController::MethodNotAllowed ？

Question

我有一个应用程序，通过模型动态加载路由，并在创建/更新该模型后调用 ActionController::Routing::Routes.reload! 。 问题是，执行此操作后，当我尝试访问该新路由时，我收到以下错误：

ActionController::MethodNotAllowed
Only get, head, post, put, and delete requests are allowed.

真正奇怪的是请求没有参数，并且响应标头为 {"cookie"=> [], “允许”==“获取， 头， 邮政， 放， 删除”， "Cache-Control"=>"no-cache"}

所有这些，即使请求肯定是 GET （根据 Firebug）并且根据响应 GET 肯定是允许的。

我正在使用 Rails 2.1.0 和 Mongrel 1.1.5（谷歌搜索后，我注意到有些旧版本存在问题）。

有人有想法吗？

Answer 1

显然这是 Rails 2.1.0 中的一个错误。 升级到 Rails 2.2.1 解决了这个问题。

Answer 2

如果您不想使用 2.2 破坏您的网站，升级到 2.1.2 也可以解决这个问题。
