我正在使用Rails 4.2.7。我想将用户重定向到另一个页面，如果他们访问网站的根目录并且他们已经登录。所以我将其添加到我的config / routes.rb文件
authenticated do
root :to => 'my_objects#index', as: :authenticated
end
root 'pages#index'
但是当我启动Rails服务器时，我收到此错误

如果用户已登录，如何从根目录实施重定向？
编辑：这是我的完整路线档案......
get 'user_my_object_time_matches/create'
get 'my_objects/index'
# The priority is based upon order of creation: first created -> highest priority.
# See how all your routes lay out with "rake routes".
# You can have the root of your site routed with "root"
root 'pages#index'
get '/auth/:provider/callback', to: 'sessions#create'
get '/logout', to: 'sessions#destroy'
delete '/logout', to: 'sessions#destroy'
resources :sessions, only: [:create, :destroy]
resources :users do
collection do
get 'edit'
end
end
resources :my_objects do
collection do
post 'create'
get 'import'
get '/index', to: redirect('/my_objects/index')
get 'search'
get 'stats'
end
end
resources :user_my_object_time_matches
resources :countries do
get :states #-> url.com/countries/:country_id/states/
end
以下是我更新页面控制器的内容......
class PagesController < ApplicationController
def index
redirect_to my_objects_path if logged_in?
end
end
但我没有被重定向到正确的页面。相反，我被重定向到一个导致“动作＆＃39;显示＆＃39;找不到MyObjectsController “错误。这是日志

位。在您的 authenticated do
root :to => 'my_objects#index', as: :authenticated
end
中，执行：
PagesController这假定：
class Pages < ApplicationController
def index
redirect_to my_objects_path if authenticated?
... do other stuff as appropriate ...
end
end
文件中有resources :my_objects之类的内容。我不确定你是否在显示你的整个路线文件。如果你没有那样的东西，你需要添加它。
您有一个名为routes.rb的方法。这只是一个例子。放入你实际拥有的任何东西。
