AngularFire2 how to use your own custom key instead of the auto generated one

Question

Currently I am using:

this.af.database.list('users').push(user);

How can I make the key of the object that is submitted be custom. So I want to be able to set the node of this object to the same uid of the registered user. I have access to this Id I just need to be able to know how to make the custom user objects node not be the auto generated id when pushing.

Thanks

Answer 1

Use a method like below with Angularfire2

addCustomKey (key, value) {
    const toSend = this.af.database.object(`/users/${key}`);
    toSend.set(value);
}

Answer 2

Here is another method you can use with AngularFire2

addCustomKey(key, value) {
    const users = this.af.database.object('/users');
    users.update({ [key]: value });
}

Answer 3

push will add a push key, just use the update method:

this.yourRef = this.af.database.list('users');
let userId = "UID", 
userInfos = { data: "your user datas" };

this.yourRef.update(userId, userInfos);

As mentioned in many of the answers above, calling push() will generate a key for you. Here's an alternative approach.

Instead, you have to use child() if you want set your custom key to determine the key/path for yourself. Like so:

firebase.database.ref().child('/path/with/custom/key/goes/here').set();

In your case, to use the user's authentication ID, here's how you approach it:

export class SomeClass {

    uid: string;

    constructor(public afDB: AngularFireDatabase, public afAuth: AngularFireAuth) {

          // Get User Auth ID
          afAuth.authState.subscribe(user => {
            this.uid = user.uid;
          });
      }

    //Your method
    this.afDB.database.ref().child(`users/${this.uid}/`).set(user);
}
