ruby-on-rails - 注册后设计重定向

Question

设计让我很难受。目前，除了注册重定向以外，其他所有功能似乎都可以正常工作。我希望设计人员在注册或登录时(登录确实有效)，在索引操作时重定向到我的城镇管理员。

我试过重写RegistrationsController，并尝试添加一个applicationController函数，例如:

  def after_sign_in_path_for(resource_or_scope)
    if resource_or_scope.is_a?(User)
      town_path
    else
      super
    end
  end

不过，我遇到了同样的错误:

NoMethodError in User/townController#index

You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.*

严重的是，我找不到办法。有什么想法吗？ :)

编辑:我的路线

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

  destroy_user_session GET    /users/sign_out(.:format)                      {:action=>"destroy", :controller=>"devise/sessions"}
         user_password POST   /users/password(.:format)                      {:action=>"create", :controller=>"devise/passwords"}
     new_user_password GET    /users/password/new(.:format)                  {:action=>"new", :controller=>"devise/passwords"}

                       PUT    /users(.:format)                               {:action=>"update", :controller=>"devise/registrations"}
                       DELETE /users(.:format)                               {:action=>"destroy", :controller=>"devise/registrations"}
                  root        /(.:format)                                    {:action=>"index", :controller=>"home"}
             user_root        /user(.:format)                                {:action=>"index", :controller=>"user/town"}
                  home        /home(.:format)                                {:action=>"index", :controller=>"home"}
                  town        /town(.:format)                                {:action=>"index", :controller=>"town"}
                 inbox        /messages(.:format)                            {:action=>"index", :controller=>"messages"}
                 inbox        /messages/inbox(.:format)                      {:action=>"inbox", :controller=>"messages"}

Routes.rb:

  devise_for :users

  root :to => "home#index"

  namespace :user do
    root :to => "town#index"
  end  

  scope :path => '/home', :controller => :home do
    match '/' => :index, :as => 'home'
  end

  scope :path => '/town', :controller => :town do
    match '/' => :index, :as => 'town'
  end
......

这就是我的工作方式。

# In your routes.rb
match 'dashboard' => 'user_dashboard#index', :as => 'user_root'

然后确保没有在 before_filter :authenticate_user! Controller 上设置 home#index。
