Grails 2.0.0.M2-级联保存问题 [英] Grails 2.0.0.M2 - cascade save problem

问题描述

我有两个简单的域类:

class Name {
 String firstName
 String lastName

 static belongsTo = [person: Person]
}

class Person {
  Name name
  String comment
}

和服务有两种方法:

class PersonService {
  Person newPerson() {
    def person = new Person()
    person.name = new Name()
    person
  }
  Person savePerson(Person person) {
    person.save()
  }
}

现在，如果我用PersonService.newPerson()创建一个新的Person，然后尝试使用grails 1.3.7使用savePerson()方法保存它，则一切正常.对于grails 1.4.0或2.0.0.M2，将引发

Now if I create a new Person with PersonService.newPerson() and then try to save it using savePerson() method using grails 1.3.7 everything works fine. With grails 1.4.0 or 2.0.0.M2 exception is thrown

'name_id'列不能为空

Column 'name_id' cannot be null

这是新的漏洞吗?还是我的代码有问题?

Is this a bug in new grails? Or maybe there is something wrong with my code?

测试方法:

void testPersonSave() {
    def person = personService.newPerson()
    person.name.firstName = 'f'
    person.name.lastName = 'l'
    person.comment = 'comment'

    personService.savePerson(person) //throws an exception
}
