我已经创建了多个用于扩展抽象用户模型的注册表单。我也将所有这些表格分别放在模板中。这是处理多种形式的正确方法吗？行中的问题 (vendordetail.save()) 不是空字段（onetoonefield 相关问题）。但我不知道如何为所有形式编写视图。请帮我解决这个问题。

Answer 1

您在哪里插入正确的 vendoruser？需要在调用 save() 之前填写。

您需要执行以下操作：

vendordetail.instance.vendoruser = request.user

如果 vendoruser 确实是当前登录的用户，否则您需要从其他地方获取它。插入后可以调用：

vendordetail.save()

编辑：我错过了您在同一页面上以另一种形式创建您的用户。在这种情况下，您可以先保存您的用户表单：

new_user = form.save()

模型表单的 save() 方法将 return 新对象，因此您之后可以将其用于其他表单：

vendordetail.instance.vendoruser = new_user
