删除设计生成模型中的用户 [英] deleting users in devise generated model

问题描述

首先我是新的轨道。我使用devise gem进行用户身份验证。现在我想给管理员一种删除其他用户的方式。用户的ID不会传递到我的销毁操作。这是我的代码

user_controller.rb

  class UsersController< ApplicationController 
 
 def destroy 
 User.find（params [：id]）。destroy 
 redirect_to dashboard_path 
 end 
 
 end 
  

dashboard.html.erb

 code><％if current_user.admin == true％> 
<％@users = User.all％> 
<％@ users.each do | user | ％GT; 
<％= user.email％> 
 | <％= link_todelete，destroy_path，method：：delete，data：{confirm：你确定}％>< br> 
<％end％> 
<％end％> 
  

解决方案

首先，您不应该分配实例变量直接在你的意见。这是控制器的责任。所以，在上面的例子中，正确的做法是这样的：

 ＃users_controller.rb 
 
 class UsersController< ApplicationController 
 def dashboard 
 @users = User.all 
 end 
 
 def destroy 
 User.find（params [：id]）。destroy 
 redirect_to dashboard_path 
 end 
 end 
  

您的视图应该看起来像这个：

 ＃dashboard.html.erb 
 
<％如果current_user.admin == true ％GT; 
<％@ users.each do | user | ％GT; 
<％= user.email％> 
 | <％= link_todelete，user，method：：delete，data：{confirm：你确定}％>< br> 
<％end％> 
<％end％> 
  

最后但并非最不重要的= P确保你的routes.rb有这样的东西：

 ＃routes.rb 
 
删除/ users /：id=> users＃destroy，as：：user 
  

当然这只是一个基于你的问题的例子，但它应该像charm = P

一样工作

First of all I am new to rails. I used devise gem for user authentication. Now I want to provide admin a way to delete other users. id of the user is not passing to my destroy action. Here is my code

user_controller.rb

  class UsersController < ApplicationController

  def destroy
    User.find(params[:id]).destroy
    redirect_to dashboard_path
  end

end

dashboard.html.erb

<% if current_user.admin == true %>
  <% @users = User.all %>
  <% @users.each do |user| %>
    <%= user.email %>
    | <%= link_to "delete", destroy_path, method: :delete, data: { confirm: "Are you sure"} %><br>
  <% end %>
<% end %>

解决方案

First of all, You shouldn't assign instance variables directly in your views. This is a Controller responsibility. So, in the above example, the right thing to do is something like this:

# users_controller.rb

class UsersController < ApplicationController
  def dashboard
    @users = User.all
  end

  def destroy
    User.find(params[:id]).destroy
    redirect_to dashboard_path
  end
end

And your view should look something like this:

# dashboard.html.erb

<% if current_user.admin == true %>
   <% @users.each do |user| %>
     <%= user.email %>
     | <%= link_to "delete", user, method: :delete, data: { confirm: "Are you sure"} %><br>
  <% end %>
<% end %>

And last but not least =P make sure your routes.rb have something like this:

# routes.rb

delete "/users/:id" => "users#destroy", as: :user

Of course it's just an example based on your question, but it should work like a charm =P
