  1. 我什么时候应该在devise_for块中嵌套路由？请给出一两个例子来展示用例。（路线#1）

  2. 如果:foo_object与:usersso :userhas_one关联:foo_object，我需要嵌套:foo_object在下面:users吗？（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

下面的例子：

devise_for :users, :path => 'accounts'

resources :users do
    resources :orders
end

上面的意思是认证路径是"/accounts/sign_in"，"/accounts_sign_up"等等。有些人可能不知道承认devise_for :users并没有实际映射到UsersController模型是很重要的。它甚至不是资源路线，尽管许多人认为它看起来像。这就是为什么我们不能这样对待它：

devise_for :users do 
   resources: somereosouce
end

所做devise_for的只是映射以下路线：

# 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"}

因此，说您可以执行以下操作但会产生一些冲突：

devise_for :users 

resource :users do 
   resource :foo_object
end

如果您有以下内容，请稍微介绍一下嵌套资源：

class Users < ActiveRecord::Base
  has_many :foo_object
end

class FooObject < ActiveRecord::Base
  belongs_to :users
end

那么您的嵌套资源将是

   resource :users do 
     resource :foo_object 
   end

希望这可以解决问题。此外，您可能想阅读带有设计的嵌套资源 - Rails3
