Question

我对Rails相当新，并且无法弄清楚我做错了什么想知道是否有人可以提供帮助？我有一个没有问题的Rails应用程序，这是在我开始修改以使其多语言之前。

为了使其多语言，我采取了以下步骤：

我将此添加到路由文件中：
范围＆＃34;（：locale）＆＃34;，：locale =＆gt; / en |是/ do

路由文件：

PropertyEvaluator::Application.routes.draw do  
  scope "(:locale)", :locale => /en|is/ do  
    root :to => "pages#home"  

    get 'pages/about'  
    get 'pages/home'  

    get "log_out" => "sessions#destroy", :as => "log_out"  
    get "log_in" => "sessions#new", :as => "log_in"  
    get "sign_up" => "users#new", :as => "sign_up"  

    resources :searches, :only => [:index, :new, :create]  
    resources :users, :only =>  [:index, :new, :create, :edit, :update, :destroy]  
    resources :sessions, :only => [:new, :create, :destroy]  
    resources :password_resets, :only =>  [:new, :create, :edit, :update]  
    resources :email_activations, :only => [:edit]   
    resources :roles, :only => [:edit, :update]  
  end  
end

修改前的路由文件：

PropertyEvaluator::Application.routes.draw do  
  root :to => "pages#home"  

  get 'pages/about'  
  get 'pages/home'  

  get "log_out" => "sessions#destroy", :as => "log_out"  
  get "log_in" => "sessions#new", :as => "log_in"  
  get "sign_up" => "users#new", :as => "sign_up"  

  resources :searches, :only => [:index, :new, :create]  
  resources :users, :only =>  [:index, :new, :create, :edit, :update, :destroy]  
  resources :sessions, :only => [:new, :create, :destroy]  
  resources :password_resets, :only =>  [:new, :create, :edit, :update]  
  resources :email_activations, :only => [:edit]  
  resources :roles, :only => [:edit, :update]  
end

到application_controller.rb我添加了

before_filter :set_locale  

def set_locale  
  I18n.locale = params[:locale] || I18n.default_locale  
  Rails.application.routes.default_url_options[:locale]= I18n.locale

对于我添加的观点：

<%= link_to_unless I18n.locale == :is, "IS", locale: :is %>  
|   
<%= link_to_unless I18n.locale == :en, "EN", locale: :en %>

原始路由文件正在按预期工作，但是当我将范围添加到路由文件时，问题就开始了。

我收到以下错误：

No route matches {:action=>"edit", :controller=>"users", :format=>nil, :id=>nil, :locale=>#<User      id: 2, email: "bjarni.sigurdsson@bodeind.is", password_hash:   "$2a$10$WzcoB5pES3TXYbWpe7xtB.yKFnqi.dhQgMXOp8/nyKi...", password_salt:  "$2a$10$WzcoB5pES3TXYbWpe7xtB.", created_at: "2014-09-30 15:20:38", updated_at: "2014-10-01 12:41:57", name: "Bjarni Sigurðsson", auth_token: "wY2cfwk-1R7fSjCvqQPaWQ", password_reset_token: nil, password_reset_sent_at: nil, admin: true, email_confirmed: true, email_activation_token: nil,   email_confirmed_at: "2014-09-30 15:20:38", role: 4>} missing required keys: [:id]

在视图中指向以下代码：

<%= link_to(t('views.shared.navbar.edit_user_profile'), edit_user_path(current_user), class: 'btn btn-primary') %>

如果我从路由文件中删除作用域，则可以正常工作，但所选的区域设置不会显示在网址中。

有人可以帮忙吗？

除了路径生成时传递:locale参数，一切都很好。看看例外情况，有：:locale=>#<User...。由于params[:locale]为nil，因此将用户视为第一个arg。使用以下内容扩展您的app控制器：

def default_url_options(options={})
  { locale: I18n.locale }
end
