I understand AngularJS runs through some code twice, sometimes even more, like $watch events, constantly checking model states etc.

However my code:

function MyController($scope, User, local) {

var $scope.User = local.get(); // Get locally save user data

User.get({ id: $scope.User._id.$oid }, function(user) {
  $scope.User = new User(user);
  local.save($scope.User);
});

//...

Is executed twice, inserting 2 records into my DB. I'm clearly still learning as I've been banging my head against this for ages!
