提前感谢。

使用

'images'：forms.ClearableFileInput（attrs={'multiple'：True}）

和

extra=1

使这个问题不同于处理典型的表单集。当您希望显示同一表单的多个实例时，将使用表单集。在您的问题中，您似乎希望显示一个

ImageField

，并让用户选择多个。如果是这样的话，你甚至不需要表单集

我将提供一个可行的示例，其中formset仅用于呈现表单中的图像字段，用户可以从该字段中选择多个图像。它可以处理

extra=3

，但我不知道为什么有人需要这样做

Post的外键真的拼写为“Post”吗？还是拼写错误？只是拼写错误对不起，当我复制到此处时，我想我键入的是错误的。我的问题是否不适合回答？我觉得你的表格逻辑不正确或不合常规。我会在它的顶部放置一个断点，然后逐步查看到底发生了什么。我是django的新手，如何添加断点？天哪，非常感谢@Jarad。你救了我一天：D。我已经试了一百次了。你的代码工作得很好。再次感谢：D
