我尝试为自己的网站创建自己的管理区域，但是当我使用名称空间或范围时，我认为此错误
<td><%= link_to 'Show', admin_user %></td>
undefined method 'user_path' for #<#<Class:0x00007efe19f773a8>:0x00007efe19f759b8>
我已经尝试更改名称空间和范围，尝试使用其他路径名
我的routes.rb
namespace :admin do
root 'admins#index'
resources :users, except: [:new, :create,:show]
end
我的admin/users_controller.rb
module Admin
class Admin::UsersController < Admin::AdminsController
before_action :set_admin_user, only: [:show, :edit, :update, :destroy]
def index
@admin_users = User.all
end
#...
end
end
rake routes

答案 0 :(得分：0)
我已经签入了沙箱项目，并且工作正常。
<td><%= link_to 'Show', admin_user_path(user_id) %></td>
这将导致users_controllers#show方法并呈现用户。
