我已经安装了设备。
我有一个链接:<%= link_to "Sign up", new_user_registration_path %>

当我安装 ActiveAdmin(对于现有型号 User)时，此链接停止工作:

undefined local variable or method `new_user_registration_path'

我对 routes.rb 使用了 git diff在这里(添加的行是黑色的):

ActiveAdmin.routes(self)
devise_for :users <强> , ActiveAdmin::Devise.config

还有 <%= link_to "Sign out", destroy_user_session_path, :method => :delete %>现在导致 /admin/logout

我该如何解决这个问题？

rake 路:

     admin_dashboard            /admin(.:format)                       {:action=>"index", :controller=>"admin/dashboard"}

我检查了旧版本，路线是:

        new_user_session GET    /users/sign_in(.:format)               {:action=>"new", :controller=>"devise/sessions"}
            user_session POST   /users/sign_in(.:format)               {:action=>"create", :controller=>"devise/sessions"}
    destroy_user_session DELETE /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"}
      edit_user_password GET    /users/password/edit(.:format)         {:action=>"edit", :controller=>"devise/passwords"}
                         PUT    /users/password(.:format)              {:action=>"update", :controller=>"devise/passwords"}
cancel_user_registration GET    /users/cancel(.:format)                {:action=>"cancel", :controller=>"devise/registrations"}
       user_registration POST   /users(.:format)                       {:action=>"create", :controller=>"devise/registrations"}
   new_user_registration GET    /users/sign_up(.:format)               {:action=>"new", :controller=>"devise/registrations"}
  edit_user_registration GET    /users/edit(.:format)                  {:action=>"edit", :controller=>"devise/registrations"}
                         PUT    /users(.:format)                       {:action=>"update", :controller=>"devise/registrations"}
                         DELETE /users(.:format)                       {:action=>"destroy", :controller=>"devise/registrations"}

最佳答案

您可能缺少的一件事是将您的用户模型声明为“可注册”以获取由 Devise 生成的注册路由。

你应该有这样的东西:

class User < ActiveRecord::Base
  # Include devise modules
  devise :database_authenticatable, :registerable, ...

我遇到过一次这个问题，这就是解决它的方法。
