Is it possible to get the following example working? I have pushed some objects into the firebase realtime-database and the reference is the UID of the signed in user. But even if I want to query the object at the reference which we can get from firebase.auth.currentUser.uid, I'm getting an error uid of NULL. Is there a way to get this functionality working?
The Vue.js Code:
import firebase from '.././firebase';
import { db } from '.././firebase';
export default {
name: 'addMatch',
data() {
return{
tableTennisData: [],
player1Name: '',
player2Name: '',
//Game 1
firstMatchPlayer1Game1: '',
firstMatchPlayer1Game2: '',
firstMatchPlayer1Game3: '',
firstMatchPlayer1Game4: '',
firstMatchPlayer1Game5: '',
}
},
firebase: {
tableTennisData: db.ref(firebase.auth().currentUser.uid).child('tableTennis'), // UID Of Null error!
},
addMatch: function (e){
e.preventDefault();
const obj = {
//Game 1
player1Name: this.player1Name,
player2Name: this.player2Name,
firstMatchPlayer1Game1: this.firstMatchPlayer1Game1,
firstMatchPlayer1Game2: this.firstMatchPlayer1Game2,
firstMatchPlayer1Game3: this.firstMatchPlayer1Game3,
firstMatchPlayer1Game4: this.firstMatchPlayer1Game4,
firstMatchPlayer1Game5: this.firstMatchPlayer1Game5,
}
firebase.auth().onAuthStateChanged(function (){
db.ref(firebase.auth().currentUser.uid).child('tableTennis').push(obj);
});
console.log(obj);
},
},
It sounds like the user isn't signed in yet.
Keep in mind that it takes a moment for Firebase to restore the user's authentication state when you load a page. If you call auth.currentUser
before that, you will get back null
.
tableTennisData: db.ref(firebase.auth().currentUser.uid).child('tableTennis'),
I don't see where you call this code, but you'll want to wrap it in an onAuthStateChanged
handler as you already do in addMatch
.
