    ¿Como puedo restringir la escritura en mi base de datos a un usuario nuevo? y agregarle el permiso de escritura hasta que sea necesario autorizarlo.

    How can I take a value from a textbox and store it in my data base?

  • Reply Anderson Sousa August 21, 2016 at 6:37 pm

    #AskFirebase I was watching tis video again and I got a question. You said the data lies in a local place when it's sync, so if I use a child_added event will all this data be sync again or just the one I called?

    Very concise tutorial

  • Reply Maarten Berkenbosch September 16, 2016 at 8:22 am

    PLEASE, is there any decent documentation on orderByChild and equalTo(). Every article or post I read on the internet about this, makes it even more confusing.
    I just can't believe that this is the answer to getting lists sorted in the GUI on the client side

    ref.child("users").orderByChild('last_update').on("value", function (snapshot) {
    snapshot.forEach(function(child) {
    console.log(child.val()) // NOW THE CHILDREN PRINT IN ORDER

    In this example you just paste JSON { 'coffee': 'coffee' } into the value field and it expands out automatically, but I have just tried it now and it is storing the value as a string , not has a nested JSON object. Has Firebase Dashboard changed?

  • Reply Marcelo Forclaz May 21, 2017 at 2:13 pm

    It seems to be easy, but is just because you are retrieving data from objects that you know his id name. But what's up when the id is a random key? How do you find the child data in that cases?

    how to get data from a nested child that has unique id?

    for example: Users -> (random uid from firebase) -> History -> (random uid from firebase again) -> (result, score, date, time)

    how to get the data from this structure? help please!!

  • Reply Himanshu MS March 3, 2019 at 6:55 pm

    How get set child key = current user uid at SAME TIME as user REGISTER his account

    I did following –
    var userId = firebase.auth().currentUser.uid

    firebase.database().ref("users/" + userId).set({
    username: uname,
    password: passw

    But it's not working properly, it creates new entry in database for that user BUT the uid is of previously registered user, not current one!
    This is really pissing me off!
