Displaying Firebase data using Angularfire2 5.0 on an Ionic template

Hey everyone, I've been encountering a problem while trying to use angularfire2 v 5.0. I was comfortable using v 4.0 before, but now that I'm transitioning to v 5.0, I'm facing some issues.

Does anyone know how I can display real-time data from Firebase in a label or input field on Ionic 3.0? Previously, I had no trouble subscribing with v 4.0, but now I'm struggling to understand why it's not working. Even though I can see the data in console.log, it's not showing up in the template.

import { Component, ViewChild } from '@angular/core';
import { IonicPage, NavController, NavParams } from 'ionic-angular';
import { AngularFireDatabase } from 'angularfire2/database';
import { Observable } from 'rxjs';

@Component({
  selector: 'page-keyboard',
  templateUrl: 'keyboard.html',
})

export class KeyboardPage {


 userNachna: Text;
  constructor(
    public navCtrl: NavController, 
    public navParams: NavParams,
    public databaseFirebase: AngularFireDatabase,   
  ) {

  }

loadDataFirebase(){
this.databaseFirebase.object('/test/').snapshotChanges()
  .subscribe(action => {
    console.log(action.type);                <-- WORKS
    console.log(action.key)                  <-- WORKS
    console.log(action.payload.val())        <-- WORKS
    this.userNachna = action.payload.val();  <-- HERE THE ERROR
  });
}

This is my Ionic 3.0 template :

<ion-input type="text" #userNachna></ion-input>

Answer №1

the design should most likely appear as follows:

<ion-input type="text" value="{{action.payload.value}}></ion-input>
