Question

我目前正在尝试在生产环境中运行我的Ruby（1.8.7）on Rails（3.0.9）应用程序。但是，在转移到生产环境时，我的路线存在重大问题。例如，在我的代码中，我提到了

user_path()

但在制作中我不得不将其改为

users_path()

除了在

中使用它之外，它似乎正在起作用

users_path(user)

生成URL

http://whatwillworkforme.com/users?format=myuser

发展会产生：

http://whatwillworkforme.com/users/myuser

我的路线如下所示。我正在使用Smartr项目代码（https://github.com/dkd/smartr），所以我不熟悉Rails 3路由或为什么做出特定决定。

WhatWillWorkForMeCom::Application.routes.draw do

  devise_for :users, :controllers => { :registrations => "registrations",
                                   :passwords      => "passwords",
                                   :sessions      => "sessions" }
  namespace :admin do
    resources :comments
    resources :treatments
    resources :conditions
    resources :users
  end

  match "/conditions/page/:page", :to => "conditions#index"
  match "/conditions/hot(/:page)", :to => "conditions#hot"
  match "/conditions/active(/:page)", :to => "conditions#active"
  match "/conditions/untreated(/:page)", :to => "conditions#untreated"
  match "/conditions/tagged/:tag(/:page)", :to => "condition#index"

  match "sitemap/" => "sitemap#index"

  match 'contact_us' => 'site#contact_us_new', :as => 'contact_us', :via => :get
  match 'contact_us' => 'site#contact_us_create', :as => 'contact_us', :via => :post

  resources :conditions, :except => [:show, :edit] do

    member do
      put :update_for_toggle_acceptance
      put :update_for_toggle_decline
    end

    collection do
      get :hot
      get :active
      get :untreated
      get :search
    end
  end

  match "/conditions/:id(/:friendly_id)", :to => "conditions#show", :as => :condition
  match "/conditions/:id/:friendly_id/edit", :to => "conditions#edit"
  match "/site/terms_and_conditions", :to => "site#terms_and_conditions"

  scope "/conditions/:condition_id/:friendly_id/" do
    get "treatment/:id/edit", :to => "treatments#edit", :as => :edit_condition_treatment
    put "treatment/:id", :to => "treatments#update", :as => :condition_treatment
    post "treatments", :to => "treatments#create", :as => :condition_treatments
  end

  match "/admin", :to => "admin#index"

  resources :comments
  resources :tags, :only => [:index]
  resources :votes, :only => [:create]

  resources :users, :except => [:destroy] do

    collection do
      get :who_is_online
      get :search
    end

    member do
      get :reputation
    end

    resources :bookmarks, :only => [:index]

  end

  resources :bookmarks, :only => [:toggle] do
    member do
      post :toggle
      get :toggle
    end
  end

  match "errors/routing", :to => "errors#routing"

  namespace :api do
    namespace :v1 do
      resources :conditions, :only => [:index]
      resources :users, :only => [:index]
    end
  end

  root :to => 'site#index'
  match '*a', :to => 'errors#routing'
end

Rake Routes（按要求）是

        new_user_session GET    /users/sign_in(.:format)         {:action=>"new", :controller=>"sessions"}
            user_session POST   /users/sign_in(.:format)         {:action=>"create", :controller=>"sessions"}

                    POST   /users(.:format)                    {:action=>"create", :controller=>"users"}
           new_user GET    /users/new(.:format)                {:action=>"new", :controller=>"users"}

               user GET    /users/:id(.:format)                {:action=>"show", :controller=>"users"}
                    PUT    /users/:id(.:format)                {:action=>"update", :controller=>"users"}

我不确定为什么开发和生产行为会有所不同，但http://whatwillworkforme.com/users?format=myuser实际上是users_path(myuser)上的预期行为。您可以通过运行rake routes来验证这一点。你应该得到以下几点：

users GET    /users(.:format)        users#index
 user GET    /users/:id(.:format)    users#show

路由中带有起始冒号的任何内容都将是您可以传递给url_for或使用它的任何内容的参数，例如。 link_to。

您应该使用user_path(user)来获取特定用户的路由（Rails会将ActiveRecord实例转换为其id，然后再将其传递到路由中。）

相反，您应该使用users_path而不使用参数，因为您使用复数路径引用整个集合。任何参数都会尝试为您的网址提供一种格式（例如。'xml'应该在网址上添加一个尾随.xml。

在您的具体情况下，请注意重复的路线：POST对/users的来电将被Devise截获，并且无法与您的控制器create进行操作。
