我的网站上有一个列表系统，目前正在创建一个页面，允许用户编辑他们的列表，我已经完成了大部分工作，但是我仍然坚持保存更新的表单。目前，如果他们保存已编辑的表单而不是更新模型，则会创建一个全新的列表条目，并且仍然保留旧的列表条目。如果有人可以请看我的代码那么好，我已经坚持这个问题很久了！

我的注册应用程序中可能会影响它的一段代码？

答案 0 :(得分：1)
您的表单action错误。将其更改为：
<form action="{% url 'editlisting' %}" class="createjoblisting" id="createjoblisting_form" method="post" >
在您复制了创建模板后，您的表单会将您的数据发布到创建商家信息的视图，而不是对其进行编辑。
