ruby-on-rails - Rails 3.0.9 + Ruby 1.9.2 p180 + Devise - 路线

Question

我正在使用 Rails 3.0.9 + Ruby 1.9.2 p180 + Devise，这是我的路线:

[...]
devise_for :users,:controllers => { :sessions => "users/sessions" }
[...]
root :to => "users/sessions#new"

我基本上想让设计登录页面成为我的根路由...但是当我尝试使用我的本地服务器(http://localhost:3000)时，我收到以下错误:

Unknown action

Could not find devise mapping for path "/". Maybe you forgot to wrap your route inside
the scope block? For example: devise_scope :user do match "/some/route" => 
"some_devise_controller" end

Answer 1

试试这个:

devise_scope :user do 
  root :to => "users/sessions#new"
end

编辑: 如果您使用的是设备的默认 Controller ，那么您将这样做:

devise_scope :user do 
  root :to => "devise/sessions#new"
end
