comment Firebase observe changes for each user in a list with iOS SDK
Your code is listening to a specific user (user valueForKey: @"userIdentifier"), so only changes to that user will trigger your block. In addition you're using observeSingleEventOfType, so your block will trigger at most once. So: make sure you're changing the correct user's node and use observeEventType:withBlock:.

comment Firebase .push() Error and ng-model not working
After you put ng-model="price" back onto the input, use itemsRef.push({ price: $scope.price }) to pass it into Firebase.

comment Firebase .push() Error and ng-model not working
You're right about itemsRef not pointing to an array. It instead points to a Firebase object, which defines a push method.

I added a sample of that. Please take the time to also study this page firebase.com/docs/android/guide/saving-data.html, which we recently updated to be a better guide of how to deal with data structures such as this.

comment Checking for existence of $firebaseObject
So listen for changes in the object (firebase.com/docs/web/libraries/angular/…) and use that to set a $scope.isDivShowing based on the $value.

comment How can I $bindTo to $firebaseObject.$value?
$bindTo establishes a three-way binding, which is not what you're looking for. Instead you'll want $scope.time = $firebaseObject(ref) and then in your HTML {{time.propertyThatHasTime}} or {{time.$value}} (depending on whether ref points to an object or a single property).

comment Firebase strange duplicate update
That 2.11.2 is your npm version, not your Firebase version. To find your Firebase version do npm ls firebase. I had a typo before, the latest Firebase JavaScript SDK is 2.**2**.7. But I cannot reproduce the behavior you're describing with the code you posted. If that requires a certain number of nodes to be present, include code to create those nodes. See stackoverflow.com/help/mcve
