Question

我正在使用Rails 4。

我想强迫游客选择他的国家。拉脱维亚和爱沙尼亚只有两种选择。

在主要布局中，我喜欢这样：

 <li><%= link_to "Latvija", :country => :latvia %></li>

<li><%= link_to "Igaunija", :country => :estonia %></li>

在路线中：

Rails.application.routes.draw do

 scope "(:country)", :locale => /latvia|estonia/ do  

  resources :reports
   devise_for :admin_users, ActiveAdmin::Devise.config
  ActiveAdmin.routes(self)
 #get "/accept" => 'home#accept_and_redirect'

   scope "(:locale)", :locale => /lv|ee|ru/ do  
     root 'home#index'

get 'advertisements/update_regions' => 'advertisements#update_regions', as: 'update_regions'

resources :reviews do
  member do
    put "like", to: "reviews#upvote"
    put "dislike", to: "reviews#downvote"
  end
end

    resources :advertisements do
         collection { post :search, to: 'advertisements#index' }
  member do
    put "like", to: "advertisements#upvote"
    put "dislike", to: "advertisements#downvote"
  end
end
   resources :services
    get "/help", to: "help#index"
  get "/rules", to: "rules#index"

 get "/blacklist", to: "blacklist#index"
  devise_for :users
    resources :users, only: [:show, :index] do
      member do
         put "like", to: "users#upvote"
         put "dislike", to: "users#downvote"

      end
    end
end
 end
end

它基本上做了什么：它将网址更改为http://localhost:3000/latvia/lv/users/sign_up（有效）但是当我去http://localhost:3000/latvia/lv/advertisements时，它给了我错误：

No route matches {:action=>"show", :controller=>"advertisements", :country=>#<Advertisement id: 82, name: "tij", region_id: 4, age: 19, height: 180, phone_number: "0202222", weight: 85,  email: "as@g.lv", description: "ahahi", created_at: "2014-11-28 14:39:12", updated_at: "2014-11-28 14:40:14", user_id: 14, country_id: 1, in_blacklist: false, admin_confirmed: false, vip: true, provaider: "few", your_ip: "wefwef">, :format=>nil, :id=>nil, :locale=>:lv} missing required keys: [:id]

因此，在scope "(:country)", :locale => /latvia|estonia/ do end之外声明的链接有效，但内部的链接无效。

什么可能导致此错误？或者是在链接中设置国家/地区的其他方式？

你只是错误地构建了预期的参数 - 或者没有传递所需的一切。看看：

No route matches {
  :action=>"show", 
  :controller=>"advertisements", 
  :country=>#<Advertisement id: 82, 
    name: "tij", 
    region_id: 4, 
    age: 19, 
    height: 180, 
    phone_number: "0202222", 
    weight: 85,  
    email: "as@g.lv", 
    description: "ahahi", 
    created_at: "2014-11-28 14:39:12", 
    updated_at: "2014-11-28 14:40:14", 
    user_id: 14, 
    country_id: 1, 
    in_blacklist: false, 
    admin_confirmed: false, 
    vip: true, 
    provaider: "few", 
    your_ip: "wefwef">, 
  :format=>nil, 
  :id=>nil, 
  :locale=>:lv
} 

missing required keys: [:id]

似乎:country实际上是Advertisement类的一个实例 - 对我来说真的没有意义，所以这可能是一个错误。可能你的范围正在弄乱另一个参数，因为它们具有相同的名称。

更重要的是，由于:id为零，因此您需要将ID传递给linked_to来电。像这样：

link_to "Latvija", :country => :latvia, :id => <whatever you want this id to be>

所有链接都坏了，Rails 4
