grails - 关系1 a 1错误插入数据

Question

我有一种关系1-1域模型

package relation1a1

class Person {
    Home home
    String name
    String aPaterno
    String aMaterno
}

package relation1a1

class Home {

    static belongsTo = [person: Person]

    String cP
    String street
}

当我将数据插入到人员表中时，要求我将数据插入到表的第一项工作中；当我尝试将数据插入到主表中时，要求我将数据插入到人表中。

我尝试做的是消除关系的1-1关系的人。

Answer 1

更改类(class)域:

package relation1a1

class Person {
    Home home
    String name
    String aPaterno
    String aMaterno
    static constraints = {
        home nullable: true //now you can save Person instance with home=null
    }
}

然后:

def person = new Person(name: "name", aPaterno: "qwe", aMaterno: "rty")
person.save(flush: true)

def home = new Home(cP: "asd", street: "fgh", person: person)
home.save(flush: true)

person.home = home
person.save()
