【问题描述】：
我创建了一个“地址”模型，供我的应用程序的许多不同部分使用。每个用户可以拥有多个专属于他们的地址。我创建了另一个属于用户的类 - 'PersonalDetails'。我希望这个类至少有一个，但最多有六个属于用户的地址。
我当前的设置（涉及清晰的表单）允许这样做，但地址字段是一个“选择”字段，其中包含当前属于该用户的地址列表。我希望用户能够使用现有地址或随时创建新地址。我该如何做到这一点？我尝试让“PersonalDetails”表单使用“AddressForm”，但没有任何乐趣。
作为额外的奖励，我最初只想呈现一个地址表单，但用户可以选择单击“添加更多地址”以获取更多地址字段。这听起来像是表单集的工作，但我不知道如何使用脆皮 - 任何帮助都会很棒！
