How to add a nested List of objects in Realm "Error: JS value must be of type: object"

Question

我正在尝试创建具有 json 对象数组和嵌套对象数组的 Realm 数据库。

当我尝试使用下面的代码添加时，我总是得到错误：JS 值必须是类型：对象。

模式：

import Realm from 'realm';

class Exercise extends Realm.Object {
}
Exercise.schema = {
    name: 'Exercise',
    primaryKey: 'id',
    properties: {
        id: 'int',
        name: 'string',
        category: 'string',
        bodyPart: 'string',
        levels: {type: 'list', objectType: 'Level'}
    }
};

class Level extends Realm.Object {
}
Level.schema = {
    name: 'Level',
    properties: {
        level: 'int',
        equipments: 'string'
    }
};

export default new Realm({schema: [Exercise, Level, Multiplier]});

以及我尝试创建数据库的方法：

 realm.write(() => {
        let exercise = realm.create('Exercise', {
            id: 209,
            name: 'Dumbbell Overhead Press',
            category: 'Military Press',
            bodyPart: 'Shoulder'
        }, true);

        exercise.levels.push({
            level: 3,
            equipments: 'DB'
        });

    });

各种方法都试过了，直接把数组放在练习创建中等等，都没有成功..

干杯

Answer 1

你必须指定记录的索引。作为 exercise.returns 记录而不是练习对象

试试这个

realm.write(() => {
    let exercise = realm.create('Exercise', {
        id: 209,
        name: 'Dumbbell Overhead Press',
        category: 'Military Press',
        bodyPart: 'Shoulder'
    }, true);
    exercise[0].levels.push({
        level: 3,
        equipments: 'DB'
    });

});
