Question

我应该何时在devise_for区块中嵌套路线？请举一个或两个示例来显示用例。（路线＃1）
如果:foo_object与:users相关联，:user has_one :foo_object，我是否需要在:foo_object下嵌套:users？（路线＃2）:users是设计:users模型。

路线＃1：

devise_for :users  
resource :foo_object

路线＃2：

devise_for :users
resources :users do      
  resource :foo_object
end

以下示例：

devise_for :users, :path => 'accounts'

resources :users do
    resources :orders
end

以上意味着身份验证路径为"/accounts/sign_in"，"/accounts_sign_up"等。有些人可能不知道确认devise_for :users实际上不是很重要映射到UsersController和模型。它甚至不是一条资源路线，尽管它看起来很像。这就是为什么我们不能像以下那样对待它：

devise_for :users do 
   resources: somereosouce
end

所有devise_for都会映射以下路线：

# Session routes for Authenticatable (default)
     new_user_session GET  /users/sign_in                    {:controller=>"devise/sessions", :action=>"new"}
         user_session POST /users/sign_in                    {:controller=>"devise/sessions", :action=>"create"}
 destroy_user_session GET  /users/sign_out                   {:controller=>"devise/sessions", :action=>"destroy"}

# Password routes for Recoverable, if User model has :recoverable configured
    new_user_password GET  /users/password/new(.:format)     {:controller=>"devise/passwords", :action=>"new"}
   edit_user_password GET  /users/password/edit(.:format)    {:controller=>"devise/passwords", :action=>"edit"}
        user_password PUT  /users/password(.:format)         {:controller=>"devise/passwords", :action=>"update"}
                      POST /users/password(.:format)         {:controller=>"devise/passwords", :action=>"create"}

# Confirmation routes for Confirmable, if User model has :confirmable configured
new_user_confirmation GET  /users/confirmation/new(.:format) {:controller=>"devise/confirmations", :action=>"new"}
    user_confirmation GET  /users/confirmation(.:format)     {:controller=>"devise/confirmations", :action=>"show"}
                      POST /users/confirmation(.:format)     {:controller=>"devise/confirmations", :action=>"create"}

所以说你可以做以下事情，但会有一些冲突：

devise_for :users 

resource :users do 
   resource :foo_object
end

关于嵌套资源的一点点，如果您有以下内容：

class Users < ActiveRecord::Base
  has_many :foo_object
end

class FooObject < ActiveRecord::Base
  belongs_to :users
end

然后您的嵌套资源将是

   resource :users do 
     resource :foo_object 
   end

希望这可以解决问题。您也可以阅读Nested Resource with Devise - Rails3
