How to push a schema object into the array property of another schema object?

Question

Description

I went through the realm-js documentation and was unable to find any examples explaining how to push an object into the array property of its parent.

To be a little more clear, I have a Schema Test which has a property data: {type: "data[]", default: []}, however I am unable to push any data objects to it.

Error:

Here is the error I get.

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

What I tried:

This is what I tried:

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

What am I doing wrong?

I also tried to directly push the data directly, but I get a similar error.

Test Schema:

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;

DeviceData Schema

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;

Is your schema name really `data`? If that is the case it might be a reserved word and might be breaking the realm code since there is already a [`data`](https://realm.io/docs/javascript/latest/#supported-types) type in realm. — bennygenel, Sep 13 '18 at 05:40

data is a reserved word for realm since it already has a data type as data. If the schema name changed to something else problem will be solved.

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
