Question

我想使用表数据旁边的链接删除存储在表中的记录。我想出的错误是：

没有路线匹配[GET]＆＃34; / carlogs / destroy＆＃34;

我的破坏方法：

def destroy
@carlog= CarLog.find(params[:id])
@carlog.destroy()

redirect_to show_path(@carlog)
end

包含删除链接的部分视图代码：

<% @carlogs.each do |car| %>
<tr>
<td><%= car.id %></td>
<td><%= car.plate_number %></td>
<td><%= car.brand %></td>
<td><%= car.slot_number %></td>
<td><%= car.is_taken %></td>
<td><%= car.created_at %></td>
<td><%= link_to "Delete", show_path(car), method: :delete, data: 
        {confirm: "Are you sure?"} %>
</tr>
<% end %>

Answer 1

确保您拥有delete REST方法：

DELETE /carlogs/:id(.:format)                     carlogs#destroy

在您的application.js中，您必须拥有以下内容：

//= require jquery_ujs

Answer 2

对销毁记录使用销毁链接，然后像

那样重定向表

方法

def destroy
 @carlog= CarLog.find(params[:id])
 @carlog.destroy()

 redirect_to show_path(@carlog) #-> Table pathe
end

的routes.rb

 delete 'destroy' => 'carlogs#destroy'

查看

<%= link_to "Delete", destroy_path, method: :delete, data: 
    {confirm: "Are you sure?"} %>

我认为会帮助你

你为什么写show_path（car）？

也许你的意思是car_path（汽车）？

<?php include('includes/config.php'); session_start(); // Use session variable on this page. This function must put on the top of page. if (!isset($_SESSION['admin_email'])) { echo "<script>window.open('login.php','_self')</script>"; } else { global $con; date_default_timezone_set('Asia/Kolkata'); $date = date('Y-m-d H:i:s'); $user = $_SESSION['admin_email']; $ip = $_SERVER['REMOTE_ADDR']; $update_last_login="UPDATE m_admins SET admin_status='ONLINE',admin_last_login='$date',active_ip_address='$ip' WHERE admin_email='$user'"; $update_last_login = mysqli_query($con, $update_last_login) or die (mysqli_error($con)); ?> <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Demo App | Welcome </title> <meta content='width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no' name='viewport'> <meta name="description" content=""> <meta name="keywords" content=""> </head> <body class="skin-black"> <div class="user-panel"> <div class="pull-left info"> <p>Hello, <?php if(isset($_SESSION['admin_email'])){ echo "".ucfirst($_SESSION['admin_name']); } ?> </p> </div> </div> </body> </html> <?php } ?>

另外，您应该检查路线<%= link_to "Delete", car_path(car), method: :delete, data: {confirm: "Are you sure?"}%>。我认为这不会出现在[GET] "/carlogs/destroy

中
