Right now, I am unwrapping my data using the method described in the
documentation
<https://github.com/angular/angularfire2/blob/master/docs/2-retrieving-data-as-objects.md#retrieving-the-snapshot>.
However, the documentation states:
*AngularFire2 unwraps the Firebase DataSnapshot by default*, but you can
> get the data as the original snapshot by specifying the preserveSnapshot
> option.
How would I be able to access the "default" unwrapping functionality (read:
access the elements of `item`) without having the manually unwrap the data
snapshot?
My data from Firebase looks like this:
{
testObj : {
firstName: "beckah",
lastName: "s"
}
}
My code (which works) is:
import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { AngularFireDatabase, FirebaseObjectObservable } from
'angularfire2/database';
@Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
item: FirebaseObjectObservable<any>;
constructor( public navCtrl: NavController,
public db: AngularFireDatabase ) {
this.item = db.object('/testObj', { preserveSnapshot: true });
this.item.subscribe(snapshot => {
console.log(snapshot.val())
});
}
}
Which outputs
Object {firstName: "beckah", lastName: "s"}
How would I be able to do the exact same thing (console.log my item object)
without manually unwrapping my snapshot like the documentation states is
possible?
Is there some kind of `this.item.get("firstName")` method?
