Question

我在Django模板中有一个循环，该循环遍历对象。
对于每个对象，我都有一个触发模态的编辑按钮。
我将id传递给每个触发该模式的编辑按钮对象ID。

模式正在打开，但问题是我无法将对象的数据传递到模式中。

模板

Answer 1

您的视图正在使用ProfileSettingsForm，而您的EducationForm并未在任何地方使用。如果我正确理解了这些模型，则您有一个Profile，它可以与多个Education实例相关。

因此，您需要在视图中具有多个EducationForm，每个对象要更新一个（可能还有一个空的对象来创建新的Education）。

您应该为此使用Django Formset，或更具体地说，使用inlineformset_factory，如here
