我的表单是2个对象，我可以以某种方式嵌入2个对象吗？

When my form gets posted, it will first create my model object#1, and if it succeeds, then it will create model object#2.

当我的表单被发布时，它将首先创建我的模型对象＃1，如果它成功，那么它将创建模型对象＃2。

My form field needs to have a mix of both input fields for both model objects.

我的表单字段需要混合两个模型对象的两个输入字段。

Can I do this using form helpers or should I just do this manually?

我可以使用表单助手来完成此操作，还是应该手动执行此操作？

Below are my models:

以下是我的模特：

My models:

我的模特：

Account
  has_many :users
  has_one  :primary_user, :class_name => 'User'

User
  has_one :account

My user table has:

我的用户表有：

account_id

My account table:

我的帐户表：

primary_user_id

So during registration/signup for an account, I want to also include the fields from the user object:

因此，在注册/注册帐户期间，我还想包含用户对象中的字段：

user_name
email
password

So when the account is created, the primary_user user account is also created.

因此，在创建帐户时，还会创建primary_user用户帐户。

How can I do this?

我怎样才能做到这一点？

PSS: Which side of the associate should be nullable, the account_id on the user table or the primary_user on the account side? Because currently I have no nulls on both sides and that won't work!

PSS：关联方的哪一方应该可以为空，用户表上的account_id或帐户方的primary_user？因为目前我双方都没有空，这是行不通的！
