How to disable firebase 3-way data binding - angularjs

Question

I am using angularJS 1.3 with angularfire and firebase.
I did create some factories that encapsulate the firebase object, and it works very well. The 3 way data binding is really cool.
I am planning to build a large application using firebase for data persistance, but I am facing a massive issue :
In my business model, I want some models/collections to support 3-way data binding, but I want other collections not to be updated live.
Some clients visiting the resulting website might be scared when they see the website's content being updated live - and I don't want that.
Imagine you are reading an article , somehow long and complexe, and you put your attention into a paragraph which you have issues understanding, and suddenly, the paragraph disappears and is replaced by a new one. Now imagine that you have no idea about web development. You might start to think to consult some professionnal about your mental health, or think your computer is hacked. Who knows !
So I would like to disable the 3 way data binding for this article, and avoid this border-line client phone calls. The only solution I found would be not to use fireangular, and use the beyond angularfire documentation section instead, and remove the following lines :
ref.on("value", function(snapshot) {
$timeout(function() {
$scope.data = snapshot.val();
});
});
This would fix the issue, but then in my admin interface, I would have to implement a second Factory so admin users can access the 3 way data binding for articles - Which is not very DRY.
In my artitcle controller, I would have to write something like this :
$scope.loadArticle = function(){
if(UserService.type === 'admin'){
AdminArticleFactory.get(id);
}
else{
ArticleFactory.get(id);
}
}
Is there any other way of setting up firebase to disable the pull updates?

Answer 1

Yeah, that is what I also ran into. Sometimes you will repeat yourself with Firebase. Also when storing data. I would recommend just making a function to save the data that you don't want to be updated instantly.
<button ng-click="saveChanges">save</button>
In controller
$scope.saveChanges = function () {
var obj = $firebaseObject(ref);
obj.foo = "bar";
obj.$save().then(function(ref) {
ref.key() === obj.$id; // true
}, function(error) {
console.log("Error:", error);
});
}
