Why is my data not showing correctly? - Utilizing Ionic 3 and Firebase

I'm experiencing a challenge with displaying Firebase data in my Ionic 3 application. Below is the relevant snippet of code from my component where 'abcdef' represents a placeholder for a specific user key:

var ref = firebase.database().ref('/profiles/abcdef/');
this.viewProfile = ref.once("value")
  .then(function(snapshot) {
    var firstName = snapshot.child("firstName").val();
    var lastName = snapshot.child("lastName").val();
    var orgName = snapshot.child("orgName").val();
    console.log(firstName+' '+lastName+' works at '+orgName );
  });

Here's how I've tried to display it in the view:

{{viewProfile.firstName}}

Despite not encountering any errors, nothing is being displayed. Any suggestions on what might be causing this?

Answer №1

Great job @Hareesh! You were so close:

let databaseRef = firebase.database().ref('/user_profiles/123456/');
    databaseRef.on('value', snapshot => {
              this.profileData = snapshot.val();
     });

Also, using {{profileData.firstName}} (without async) appears to be working perfectly.

Thanks a lot for your help!

Answer №2

To retrieve the data, a snapshot loop is required

Give this a shot

let reference = firebase.database().ref('/profiles/123456/');
reference.once("value")
  .then(function(snapshot) {
      snapshot.forEach(function(data) {
          this.displayProfile = data.val();
      }
 });
