如何迭代具有内联结构的表单集

Question

我面临着无法迭代表单集的问题。我已经在客户端模型(表单(和电话模型(表单集(之间创建了一个内联结构。我的目标是能够为每个客户存储一部以上的手机。

问题是，尽管我可以创建多个内联，但在存储阶段，我的代码只存储最后一个电话，而不是预期的每个电话

我注意到phone=PhoneFormSet.save(commit=False(行只返回一个实例。为什么会发生这种情况？

任何帮助都将不胜感激。

Answer 1

尝试更改

phones = PhoneFormSet.save(commit=False) for instance in phones: instance.save()

进入

phones = PhoneFormSet.save(commit=False) 
phones.instance=self.object
phones.save()

Answer 2

修复它与模板中的前缀有关。它必须是前缀："phone_set">，而不是前缀："client_phone_set"，就像我以前那样。
