【问题描述】：
我们已经完成了一个使用 Bootstrap Modals 创建前端管理仪表板的项目。
当我们从 ASP 模式更新记录时，我们使用 JSON 输出和 JQuery 来填充表单中的数据，因为我们发现这不能仅由 Django 完成。
我们遇到的问题是我们可以使用填充的 JSON 数据添加新记录，但我无法编辑现有记录。即使 JQUERY 和 JSON 在我们点击提交时带来了正确的数据，它也无法关联到数据库中的记录。
我们如何更新正确的记录？
我们尝试的另一种方法是通过 URL 传递 ID（与预订相关），但这会一直重定向页面而不是停留在模式上。
我就不多说了，下面是问题的相关代码。
我不擅长编程，所以希望这对我们正在努力实现的目标有所帮助，在此先感谢我们在此问题上可以获得的任何帮助。
