在 railstutorial.org 的第 10 章，我无法通过浏览器删除用户。所有测试都通过了，包括用户删除测试，但是当试图通过指向 localhost:3000 的浏览器以管理员身份删除用户时，我只是被定向到用户的个人资料。
<%= link_to "delete", user, :method => :delete, :confirm => "Are you sure?", :title => "Delete #{user.name}" %>
是用于生成删除链接的代码。
<%= javascript_include_tag :defaults %>
已包含在标题中。
我真的很困惑为什么会这样。服务器的日志显示了对用户信息的 GET 请求，正如人们在被定向到用户页面而不是破坏用户时所期望的那样。
此外，使用button_to而不是link_to将删除用户，但不会确认操作。
编辑：按请求添加 routes.rb
resources :sessions, :only => [:new, :create, :destroy]
resources :users
match '/contact', :to => 'pages#contact'
match '/about', :to => 'pages#about'
match '/help', :to => 'pages#help'
match '/signup', :to => 'users#new'
match '/signin', :to => 'sessions#new'
match '/signout', :to => 'sessions#destroy'
root :to => 'pages#home'
get "pages/home"
get "pages/contact"
get "pages/about"
get "pages/help"
编辑：application.js 按请求添加
require jquery
require jquery_ujs
require_tree .
编辑：按请求添加的 users_controller.rb
class UsersController < ApplicationController
before_filter :authenticate, :only => [:index, :edit, :update, :destroy]
before_filter :correct_user, :only => [:edit, :update]
before_filter :admin_user, :only => :destroy
