AngularJS : Prevent error $digest already in progr

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 $apply() from the scope of my controllers and directives. The problem with this is that it keeps throwing an error to the console that reads :

Error: $digest already in progress

Does anyone know how to avoid this error or achieve the same thing but in a different way?

similar to answers above but this has worked faithfully for me... in a service add:

    //sometimes you need to refresh scope, use this to prevent conflict
    this.applyAsNeeded = function (scope) {
        if (!scope.$$phase) {
            scope.$apply();
        }
    };
