Rails:我安装了ActiveAdmin,我的设备链接停止工作

Question

我已经安装好了.
我有一个链接:<%= link_to "Sign up", new_user_registration_path %>

当我安装ActiveAdmin(对于现有模型User)时,此链接停止工作:

undefined local variable or method `new_user_registration_path'

我使用git diff routes.rb,这里是(添加的行是黑色):

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

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

我怎么解决这个问题？

耙路线:

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

          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"}

                     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"}

       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"}

                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, ...

我遇到过这个问题,这就是解决它的问题.

Answer 2

看来您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，然后运行以下命令：

rails generate active_admin:resource AdminUser
rake db:migrate

这将创建一个AdminUser与您网站的用户完全没有联系的模型。
