Ruby on rails Rails表单_有问题：表单数据未保存在Rails中的控制器实例中

我试图通过使用AJAX发布控制器实例来保存座位号。单击提交按钮后，响应标题显示

STATUS 200 OK

，单击预览（响应）后，数据显示在同一页面上。 我的管制员票方法座位

路由.rb文件

get '/tickets/seat' => 'tickets#seat', as: 'seat'
post '/tickets/seat' => 'tickets#seat'

seat.html.erb

响应预览

有人能告诉我为什么我的数据没有保存在controller实例变量中吗？

首先，为什么需要编写自定义jqeury来执行ajax？从表单中删除

local:true

将发送AJAX请求。此外，您在控制器中的

seat

操作没有做任何有意义的工作。我强烈建议您进行实践，这将帮助您识别问题并解决它。首先，为什么您需要编写自定义jqeury来实现ajax？从表单中删除
