表单提交到Grails中

多个域对象我非常中的Grails一个新手。我正在学习一个基本的CRUD操作。这里我有2个域对象Person和Address。每个人只需要表单提交到Grails中

所以我有一个GSP形式收集用户名，名字，姓氏，年龄和地址字段，并应保存到数据库中Person和Address基本上2表，只有一个地址。那么如何将代码写入映射2个域类的控制器（Person & Address）。

感谢您的回答。

UPDATE：我用下面的代码没有工作

package com.deltaintech.wr 

class Person { 
    String username 
    String password 
    String firstname 
    String lastname 
    String email 
    Address address 

    static constraints = { 
    } 
} 


package com.deltaintech.wr 

class Address { 

    String address1 
    String address2 
    String city 
    String state 
    String country 
    String zipcode 

    static constraints = { 
    } 
} 

package com.deltaintech.wr.register 
import com.deltaintech.wr.* 

class RegisterController { 

    def index = { 

    } 

    def register = { 

     Person person = new Person(params) 
     person.save() 

    } 
}

我认为我忘记了一些东西。请尝试以下操作：将static belongsTo = [person：Person]添加到地址域类。在同一时间内保存两个域类所需的人员和地址之间建立了双向关系。如果你不想要这个，你可以在控制器类中执行以下操作：Address adr = new Address（params.address）; Person person = new Person（params）; person.address = adr.save（）; – hitty5 2011-06-07 09:34:31

class Person { 
    String name 
    Address address 
} 

class Address { 
    String city 
}

普惠制不得不看somethink像：

<g:form action="save"> 
    <g:textField name="name"/> 
    <g:textField name="address.city"/> 
</g:form>

控制器

：

def p = new Person(params) 
p.save()
