Django - 更新内联表单集不更新
Django - update inline formset not updating
我正在尝试创建一个更新视图，其中包含一些内联表单集，但出于某种原因，我看到 'id: This field is required.' 和 none 设置了内联表单集值单击更新按钮。这些字段本身在模板中实际上有值，所以我不确定为什么在尝试保存时内联表单集会为空。

无论何时手动呈现表单，都应该记住总是呈现它的隐藏字段，对于表单集/内联表单集更是如此，因为它自动向表单添加一些隐藏字段。由于 formset 正在更新多个实例，因此 formset 中当然需要有一些东西来指示 哪个 实例是哪个，这是由此处的隐藏字段完成的。
因此您需要呈现表单集表单的隐藏字段：
