Question

新手到rails并且一般来说这里编程！我正在进行rails教程，目前在第10章，其中用户模型已基本完成。我正在尝试通过在destroy操作旁边提供指向其他管理员用户的链接来添加新功能以使用户成为管理员用户。

我的链接定义如下：

  <% if current_user.admin? && !current_user?(user) %>  
    | <%= link_to "Make admin", user, method: :makeAdmin,
                                  data: { confirm: "You sure?" } %>
  <% end %>

我的控制器定义：

  def makeAdmin
    @user = User.find(params[:id])
    @user.update_columns(admin_user: true)
    flash[:success] = "Made an admin"
    redirect_to @user
  end

我希望以上工作正常，但是我遇到了路由错误，所以在搜索了stackoverflow后，我对路由进行了一些修改，如下所示：

  resources :users do
    member do
      put 'makeAdmin'
    end
  end

它仍然无效，路由错误仍然存在。

有什么想法吗？

Answer 1

尝试解决此问题：

<%= link_to "Make admin", make_admin_user_path(user), method: :put,
                              data: { confirm: "You sure?" } %>

Answer 2

这完成如下！

路线

resources :users do
    member do
      put 'makeadmin'
    end
  end

Controller Def

  def makeadmin
    @user = User.find(params[:id])
    @user.update_attribute :admin, true
    flash[:success] = "this user was made admin"
    redirect_to users_url
  end

链接

| <%= link_to "Make admin", makeadmin_user_path(user), :method=> :put %>
