Rails：我安装了 ActiveAdmin，但我的设计链接停止工作

Question

我已经安装了设计。
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'

我将 git diff 用于routes.rb，这里是（添加的行是黑色的）：

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

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

我该如何解决这个问题？

耙路线：

     admin_dashboard            /admin(.:format)                       {:action=>"index", :controller=>"admin/dashboard"}
         admin_codes GET        /admin/codes(.:format)                 {:action=>"index", :controller=>"admin/codes"}
                     POST       /admin/codes(.:format)                 {:action=>"create", :controller=>"admin/codes"}

     edit_admin_code GET        /admin/codes/:id/edit(.:format)        {:action=>"edit", :controller=>"admin/codes"}
          admin_code GET        /admin/codes/:id(.:format)             {:action=>"show", :controller=>"admin/codes"}
                     PUT        /admin/codes/:id(.:format)             {:action=>"update", :controller=>"admin/codes"}
                     DELETE     /admin/codes/:id(.:format)             {:action=>"destroy", :controller=>"admin/codes"}
         admin_users GET        /admin/users(.:format)                 {:action=>"index", :controller=>"admin/users"}
                     POST       /admin/users(.:format)                 {:action=>"create", :controller=>"admin/users"}
      new_admin_user GET        /admin/users/new(.:format)             {:action=>"new", :controller=>"admin/users"}
     edit_admin_user GET        /admin/users/:id/edit(.:format)        {:action=>"edit", :controller=>"admin/users"}
          admin_user GET        /admin/users/:id(.:format)             {:action=>"show", :controller=>"admin/users"}
                     PUT        /admin/users/:id(.:format)             {:action=>"update", :controller=>"admin/users"}
                     DELETE     /admin/users/:id(.:format)             {:action=>"destroy", :controller=>"admin/users"}
      admin_comments GET        /admin/comments(.:format)              {:action=>"index", :controller=>"admin/comments"}
                     POST       /admin/comments(.:format)              {:action=>"create", :controller=>"admin/comments"}
   new_admin_comment GET        /admin/comments/new(.:format)          {:action=>"new", :controller=>"admin/comments"}
  edit_admin_comment GET        /admin/comments/:id/edit(.:format)     {:action=>"edit", :controller=>"admin/comments"}
       admin_comment GET        /admin/comments/:id(.:format)          {:action=>"show", :controller=>"admin/comments"}
                     PUT        /admin/comments/:id(.:format)          {:action=>"update", :controller=>"admin/comments"}
                     DELETE     /admin/comments/:id(.:format)          {:action=>"destroy", :controller=>"admin/comments"}
    new_user_session GET        /admin/login(.:format)                 {:action=>"new", :controller=>"active_admin/devise/sessions"}
        user_session POST       /admin/login(.:format)                 {:action=>"create", :controller=>"active_admin/devise/sessions"}
destroy_user_session DELETE|GET /admin/logout(.:format)                {:action=>"destroy", :controller=>"active_admin/devise/sessions"}
       user_password POST       /admin/password(.:format)              {:action=>"create", :controller=>"active_admin/devise/passwords"}
   new_user_password GET        /admin/password/new(.:format)          {:action=>"new", :controller=>"active_admin/devise/passwords"}
  edit_user_password GET        /admin/password/edit(.:format)         {:action=>"edit", :controller=>"active_admin/devise/passwords"}
                     PUT        /admin/password(.:format)              {:action=>"update", :controller=>"active_admin/devise/passwords"}
                root            /                                      {:controller=>"codes", :action=>"list"}
                                /:controller(/:action(/:id(.:format)))

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"}

Answer 1

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, ...

我曾经遇到过这个问题，这就是解决它的方法。

Answer 2

您似乎对普通用户和管理员用户使用相同的模型。 ActiveAdmin 需要一个单独的管理员模型。尝试恢复生成器所做的更改，然后运行：

rails generate active_admin:resource AdminUser
rake db:migrate

这将创建一个AdminUser 模型，该模型与您网站的用户完全没有链接。

Answer 3

在 routes.rb 中，指定 devise_for :users 这将恢复设计用户的路线
