我有一个使用多个formset的表单。 formset表单是通过JS动态添加的。我一直在寻找一些不同的地方来帮助自己。
Add a dynamic form to a django formset using javascript in a right way
和
A nice post by Kevin Dias - Django class-based views with multiple inline formsets
我遇到的问题是，当我发布我的数据时，外部表单有数据，但是当我开始循环遍历时，我的表单集中没有任何数据实际上在cleaning_data字典中有任何数据。对我可能缺少什么的想法？第二个formset添加了一个非常相似的JS方法。
