如何将模式对象推送到另一个模式对象的数组 属性 中？

Question

描述

我浏览了 realm-js documentation，但找不到任何示例来解释如何将对象推入其父对象的数组 属性。

更清楚一点，我有一个架构 Test，其中有一个 属性 data: {type: "data[]", default: []}，但是我无法将任何 data 对象推送到它.

错误：

这是我得到的错误。

Property must be of type 'data', got ([object RealmObject])

我尝试了什么：

这是我试过的：

this.realm.write(()=>{
  const dataObj = this.realm.create('data', data);
  this.user.test.data.push(dataObj);
})

我做错了什么？

我也试过直接push数据，也报了类似的错误

测试架构：

class Test{
}

Test.schema = {
    name: "test",
    primaryKey: "id",
    properties: {
        id: "string",
        start: "date?",
        duration: "int", //in seconds
        capsule_id: "string",
        creation: "date",
        status: "int",
        height: "float",
        weight: "float",
        time_of_evolution: "string",
        treatment: "bool",
        data: {type: "data[]", default: []},
        symptoms: {type: "symptom[]", default: []},
        meals: {type: "meal[]", default: []},
        device: "device?",
        ph11: "int?",
        ph71: "int?",
        ph12: "int?",
        ph72: "int?",
        cardinal_symptoms: {type: "cardinal_symptom[]", default: []},
    }
};

export default Test;

设备数据架构

class DeviceData{}

DeviceData.schema = {
    name: 'data',
    primaryKey: "timestamp", //check to see if this is a good idea
    properties: {
        ph1: 'int',
        ph2: 'int',
        x: 'int',
        y: 'int',
        z: 'int',
        timestamp: 'int',
        raw: 'string' //base64, incase something went wrong
    }
};

export default DeviceData;

data 是领域的保留字，因为它已经有一个 data type 作为 data。如果将架构​​名称更改为其他名称，问题将得到解决。

Realm supports the following basic types: bool, int, float, double, string, data, and date.

• bool properties map to JavaScript boolean values
• int, float, and double properties map to JavaScript number values. Internally int and double are stored as 64 bits while float is stored with 32 bits.
• string properties map to string
• data properties map to ArrayBuffer
• date properties map to Date
