表單提交到Grails中

多個域對象我非常中的Grails一個新手。我正在學習一個基本的CRUD操作。這裏我有2個域對象Person和Address。每個人只需要表單提交到Grails中

所以我有一個GSP形式收集用戶名，名字，姓氏，年齡和地址字段，並應保存到數據庫中Person和Address基本上2表，只有一個地址。那麼如何將代碼寫入映射2個域類的控制器（Person & Address）。

感謝您的回答。

UPDATE：我用下面的代碼沒有工作

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() 

    } 
}

我認爲我忘記了一些東西。請嘗試以下操作：將static belongsTo = [person：Person]添加到地址域類。在同一時間內保存兩個域類所需的人員和地址之間建立了雙向關係。如果你不想要這個，你可以在控制器類中執行以下操作：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()

我將我用過的代碼添加到了我的原始評論中，請參閱 – srisris 2011-06-07 08:50:22
