Rails 3.0 中奇怪的路由错误 [英] Weird routing error in Rails 3.0
问题描述
我一直在将我的 Rails 2.3.9 应用程序转换为 Rails 3.0，一切都进展顺利.我用新系统创建了很多路线，所以我觉得我知道如何做到这一点.但是，我最近遇到了一个无法解决的路由错误.
I've been converting my Rails 2.3.9 application to Rails 3.0 and everything has been going well. I've created a lot of routes with the new system so I feel like I know how to do this. However, I recently got a routing error I can't solve.
我有一个这样定义的用户资源:
I have a users resource defined like this:
resources :users do
member do
get 'activate'
get 'edit_password'
post 'update_password'
end
collection do
get 'forgot_password'
post 'send_reset_instructions'
end
end
失败的路由是 update_password.如果我将其更改为 get 方法，它将起作用.但当用作帖子时则不然，数据来自edit_password"中的表单.
The failing route is update_password. If I change it to a get method it works. But not when used as a post, with data coming from a form in "edit_password".
这是错误信息:
Routing Error
No route matches "/users/31/update_password"
这是rake routes的(相关)输出:
activate_user GET /users/:id/activate(.:format) {:action=>"activate", :controller=>"users"}
edit_password_user GET /users/:id/edit_password(.:format) {:action=>"edit_password", :controller=>"users"}
update_password_user POST /users/:id/update_password(.:format) {:action=>"update_password", :controller=>"users"}
forgot_password_users GET /users/forgot_password(.:format) {:action=>"forgot_password", :controller=>"users"}
send_reset_instructions_users POST /users/send_reset_instructions(.:format) {:action=>"send_reset_instructions", :controller=>"users"}
users GET /users(.:format) {:action=>"index", :controller=>"users"}
users POST /users(.:format) {:action=>"create", :controller=>"users"}
new_user GET /users/new(.:format) {:action=>"new", :controller=>"users"}
edit_user GET /users/:id/edit(.:format) {:action=>"edit", :controller=>"users"}
user GET /users/:id(.:format) {:action=>"show", :controller=>"users"}
user PUT /users/:id(.:format) {:action=>"update", :controller=>"users"}
user DELETE /users/:id(.:format) {:action=>"destroy", :controller=>"users"}
最后，这是该请求 (webrick) 的 Web 服务器的输出:
Finally, this is the output of the web server for that request (webrick):

你能从中找到什么逻辑吗?
Can you find any logic in this?
我正在使用 gem (3.0.1) 提供的最新 Rails.起初我确实在 User-model 中重写了 *to_param* 以使用用户名，但无论如何问题都是一样的.
I'm using the latest Rails available through gem (3.0.1). At first I did override *to_param* in the User-model to use the username, but the problem is the same no matter what.
我检查了模型的 update_password 方法中的拼写错误，并确保它不是私有的.
I've checked for misspellings in the update_password method of the model, and also made sure it is not private.
推荐答案
我也注意到了这一点，仅使用 POST 方法且仅在使用成员"时，与您的示例相同，即:
I have noticed this as well, only with the POST method and only when using "member", so same as your example, ie:
resources :forum_posts do
member do
post :preview
end
end
会触发这个，但将其更改为 GET 或使用集合都可以正常工作，因此似乎是 rails 路由的错误；我现在通过在我的资源上方添加以下内容来解决这个问题:forum_posts do line:
will trigger this, but changing it to GET or using collection both work fine, so seems to be a bug with rails routes; I get around this for now by adding the following just above my resources :forum_posts do line:
match '/forum_posts/:id/preview(.:format)', :to => "forum_posts#preview", :as => :preview_forum_post
然后一切继续工作；简单的临时修复.
then everything continues working; easy temporary fix.
