Reset method on a $FirebaseArray in AngularFire

reset_method.js

var ResetFactory = $FirebaseArray.$extendFactory({
  
  reset: function(itemOrIndex) {
    var self = this;
    var key = self.$keyAt(itemOrIndex);
    self.$inst().$ref().once('value', function(snap) {
      self.$$updated(snap);
    });
  }
  
});

Hi katowolf,

Great snippets! A small suggestion: could you add the current version of Firebase, AngularFire etc with each snipped. I tried to use this and it failed because Firebase is changing rapidly (which is a good thing).

I was able to modify your code for the current version of Firebase and AngularFire (2.3.1 and 1.1.3). I hope this helps someone:

app.factory('ResetFactory', function($firebaseArray) {
    return $firebaseArray.$extend({
        reset: function(itemOrIndex) {
            var key, self;
            self = this;
            key = self.$keyAt(itemOrIndex);
            self.$ref().child(key).once('value', function(snap) {
               self.$$updated(snap);
            });
        }
    });
});
