我实现了devise＆devise_invitable，其中user.admin可以拥有许多酒店，随后可以邀请用户选择特定的酒店。
问题
我想为属于酒店的所有用户生成索引页（无论他们是否接受邀请）。不幸的是，我收到以下错误消息：
Could not find devise mapping for path "/hotels/9/users".
This may happen for two reasons:
1) You forgot to wrap your route inside the scope block. For example:
devise_scope :user do get "/some/route" => "some_devise_controller" end
2) You are testing a Devise controller bypassing the router.
If so,you can explicitly tell Devise which mapping to use:
@request.env["devise.mapping"] = Devise.mappings[:user]
代码
路线
Rails.application.routes.draw do
devise_for :users
resources :hotels do
devise_for :users,:controllers => { :invitations => 'users' }
resources :users,only: [:index]
end
end
