嗨，我是 Rails 的新手，我已经设法完成了 Hartl 的第 9 章。我有 3 次失败的测试来完成本章。

终端返回：

我真的不确定这里出了什么问题，因为我真的试图忠实于教程。有任何想法吗？谢谢西蒙。

因为您收到以下消息：

AbstractController::ActionNotFound:
   The action 'destroy' could not be found for UsersController

您必须destroy在您的UsersController.

class UsersController < ApplicationController

  .
  .
  .

  def destroy
    @user = User.find(params[:id])
    @user.destroy
    flash[:success] = 'User was deleted with success.'
    redirect_to users_path
  end
end

并创建能够删除每个用户的链接。

在你的 `app/views/users/index.html.erb' 中，你应该有这样的东西：

<% @users.each do |user| %>
<p><%= link_to user.name, user_path(user), method: delete, confirm: 'Are you sure?' %></p>
<% end %>

希望它可以帮助你。
