Firebase: setting additional user properties

rated 0 times [ 185] [ 3] / answers: 1 / hits: 27260 / 8 Years ago, tue, may 24, 2016, 12:00:00

I'd like to add a property to a Firebase user object. The user documentation says that I can only store additional properties using the Firebase real time database.

I am unsure on how this can works in practice.

What does the following mean in practice?

You cannot add other properties to the Firebase User object directly;
instead, you can store the additional properties in your Firebase
Realtime Database.

I interpret it as following:

you cannot modify properties of a FIRUser object but you can combine this with additional objects

I found the set function documentation which I interpet in this way:

  var userRef = ref.child(users);

  userRef.set({

    newfield: value

  });

Is this a sensible approach?

You're almost there. In the legacy Firebase documentation, we had a section on storing such additional user data.

The key is to store the additional information under the user's uid:

    let newUser = [

        provider: authData.provider,

        displayName: authData.providerData[displayName] as? NSString as? String

    ]

    // Create a child path with a key set to the uid underneath the users node

    // This creates a URL path like the following:

    //  - https://<YOUR-FIREBASE-APP>.firebaseio.com/users/<uid>

    ref.childByAppendingPath(users)

       .childByAppendingPath(authData.uid).setValue(newUser)

I've added a note that we should add this information in the new documentation too. We just need to find a good spot for it.
