how to get firebase.database.Reference full path

Question

consider

var adaRef = firebase.database().ref(\"users/ada\");

How can I get the full path of ref ? that is \"users/ada\" ?

Answer 1

That's surprisingly simple:

adaRef.toString()

Will print the full URL: https://<your-app>firebaseio.com/users/ada

So to just get the path, you substring it out of there. Two ways of doing that are:

adaRef.toString().substring(firebase.database().ref().toString().length-1)

or:

adaRef.toString().substring(adaRef.root.toString().length-1)

both will print /users/ada

Answer 2

On new versions of the framework you could use:

snapshot.ref.path.toString()

being snapshot the result of a call on a Database Reference.

Maybe this can be helpful.

Answer 3

Following on Frank's answer I extended firebase as follows:

firebase.database.Reference.prototype.fullkey = function() {
    return this.toString().substring(this.root.toString().length-1);
}

then you can do adaRef.fullkey() // returns /users/ada

(I would like to call this 'path' but that seems to be reserved by FB)
