mvc / c# /Razor/EF处理来自多个局部'create视图'的数据

为了注册一个新客户，我在我的视图上有几个部分，它们引用数据库中相应的表。主键是标识字段，这就是视图上没有id的原因。要插入新客户，我需要插入3个地址(访问地址、邮政地址和联系人地址)，然后插入合同、contact_person一行(使用已经插入的地址之一的addressId)，最后继续插入新客户，该客户将包含引用刚刚插入的访问地址和邮政地址、合同和联系人的外键。

你能推荐最好/最简单的方法来传递数据从这些部分视图作为对象CustomerController和处理那里的对象吗?如能提供处理类似情况的示例链接，我们将不胜感激。
