Question

我想暂时隐藏一些声明的记录，并更新余额。

请参阅屏幕截图以便更好地理解，如下所示;

我想要的是，当我点击隐藏按钮时，它应该完全隐藏行，并且必须结转余额。当点击显示全部时，它必须显示所有记录。

我在表格中创建了隐藏字段，并在控制器中编写了hide_xvaziri方法但与hide button_to函数混淆，以便获取＆＃39; / xvaziri /：id / hide＆＃39;，以：＆＃39;＃xvaziris hide_xvaziri＆＃39;

你为什么要尝试用rails做这个？

你想要的是在前端隐藏/显示元素。

更好的方法是使用javascript / jquery

这里有很多例子：

在这里你可以看一下jquery文档：

在rails 4.2中临时隐藏表记录
