React native Realm React Native：如何从对象'；带条件的s嵌套数组

我是React native的新手，尝试将Realm集成为客户端数据库。 我有两个模式：

export const CAR_SCHEMA = {
  name: 'Car',
  properties: {
    color: 'string',
    model: 'string',
  }
};

export const PERSONS_SCHEMA = {
  name: 'Person',
  primaryKey: 'id',
  properties: {
    id: 'int',
    firstName: 'string',
    lastName: 'string'
    cars: 'Cars[]'
  }
};

我的问题基本上是指如何将“车”从车所在的“人”中删除。model='Honda'？我找不到任何关于从对象的嵌套数组中删除元素的文档。

从数组中删除，但将项保留在域中：

realm.write(() => {
    let person = realm.objectForPrimaryKey('person', personId);
    let carsOfPerson = person.cars;

    var i = carsOfPerson.length - 1;
    while(i >= 0) {
        if(carsOfPerson[i].model == "Honda") {
            carsOfPerson.splice(i, 1);
        }
        i--;
    }
});

通过从域中删除项从数组中删除：

realm.write(() => {
    let person = realm.objectForPrimaryKey('person', personId);
    let carsOfPerson = person.cars;
    let hondasOfPerson = carsOfPerson.filtered('model = "HONDA"')
    realm.delete(hondasOfPerson)
});
