AngularJS : Prevent error $digest already in progress when calling $scope.$apply()

Question

I\'m finding that I need to update my page to my scope manually more and more since building an application in angular.

The only way I know of to do this is to call

Answer 1

The digest cycle is a synchronous call. It won't yield control to the browser's event loop until it is done. There are a few ways to deal with this. The easiest way to deal with this is to use the built in $timeout, and a second way is if you are using underscore or lodash (and you should be), call the following:

$timeout(function(){
    //any code in here will automatically have an apply run afterwards
});

or if you have lodash:

_.defer(function(){$scope.$apply();});

We tried several workarounds, and we hated injecting $rootScope into all of our controllers, directives, and even some factories. So, the $timeout and _.defer have been our favorite so far. These methods successfully tell angular to wait until the next animation loop, which will guarantee that the current scope.$apply is over.
