For example my parent controller variable name is

$scope.studentInfo = {
    studentId: 1,
    name: 'aaaa',
    address: {
        doorno: 153,
        street: 'Gandhi street'
    }
}

I am changing the this parent variable through child controller example, changing the variable to some other value

$scope.student = angular.copy($scope.studentInfo);
$scope.studnet.address.doorno = 150;
$scope.studentInfo = $scope.student;

then if we assigning the value to parent controller, then the value will be changing alone in child controller but not parent controller. If I assign each and every property then the value will reflect in parent json also.

how do you access the parent $scope from the child $scope? – fodma1 Mar 11 '16 at 07:38
First I will assign this parent variable to my child controller variable For example $scope.userInfo = $scope.studentInfo – Parthipan S Mar 11 '16 at 07:40
Primitives are passed by value, objects by reference. – dfsq Mar 11 '16 at 07:42
I mean do you use `$scope.$parent` or how do you access it? http://stackoverflow.com/a/21454647/2419215 – fodma1 Mar 11 '16 at 07:45
No you can directly access the variable in child controller – Parthipan S Mar 11 '16 at 08:50
If we using angular copy to avoid unnecessary changes because of that only we should assign the each and every property manually. – Parthipan S Mar 11 '16 at 08:53
@ParthipanS You could use a `factory` to capture the changes between controllers. – Mar 11 '16 at 09:29
