【中文标题】无法更新自定义用户 (AbstractUser)

【英文标题】：Cannot Update Custom User (AbstractUser)

【问题描述】：

我正在使用从 AbstractUser 继承的自定义用户模型，当我保存用户时它运行良好。 但是当我需要更新模型并单击模板上的提交按钮时，什么也没有发生。控制台中什么都没有显示，页面没有重新加载，什么都没有。 我真的很感激这里的一些指导？

【问题讨论】：

表单标签在哪里？？

我正在使用 Django 脆皮表单，因此表单标签使用脆皮表单呈现。

self.helper.form_tag = False # use false if you want to render the form tags manually 这是你自己代码中的一行...

我不确定你在上一条评论中所说的 Abdul.

【参考方案1】：

页面渲染完成后，查看页面源代码。 检查脆的表单是否真的包含表单标签。

我以前没有使用过脆的表格，但我不得不问，你不应该以某种方式描述表格的结束位置吗？

也许你错过了什么...
