Deepstream 1 - n relation - deepstream.io

Question

I'm trying to build a user notification using Deepstream.io. I'm using deepstream.io-storage-mongodb for storage. My data structure:
User
=================
id - email - others
Notication
=================
userId - notification
I'm try to implement 1-n modelling deepsteam tutorial. But I can't understand how can I do this. How can I store pointer or how can I point towards a List ? Or how can I implement notification using deepstream ?
Thanks in Advance.

Answer 1

you can try as like as given below (I'm using JS):
Receive Notication
var client = deepstream( 'localhost:6020' );
client.login();
// Unique Identification for user
let uniqueId = `userId:${userId}`;
// Mongodb collection : Notification
statusRecord = client.record.getList("Notification/" + uniqueId);
statusRecord.subscribe(function(data) {
data.forEach(function(name) {
var record = client.record.getRecord(name);
record.whenReady(function(r) {
// all notification
console.log( "r ==> ", r.get() );
});
});
});
Send Notification
const ds = deepstream( 'localhost:6020' );
ds.login();
// userId
const list = this.ds.record.getList( `Notification/${userId}` );
// id for notification
let id = `Notification/${this.ds.getUid()}`;
let record = this.ds.record.getRecord(id);
record.set( {
message: 'information'// save notification data
});
list.addEntry(id);
Hope it will solve your problem.
