Building nested objects within an isolated scope can be achieved by following these steps

I am trying to implement a nested structure on my nested scope within a directive, as shown below:

angular.module('myAddress').directive('myAddress', [function () {
    return {
        restrict: 'AE',
        controller: 'myAddressController',
        templateUrl: 'my-address.html',
        scope: {
            address: {
                'form': '=addressForm',
                'model': '=addressModel'
            }
        }
    };
}]);

However, I am encountering an exception stating that undefined is not a function when I have the address nesting in place. This exception does not occur when I remove the address nesting.

Is there a way to include attribute arguments inside a named key on my scope?

Addtionally, when I define $scope.address within the controller, it does not work either. I am wondering which will be executed first - the scope: { 'form' = 'addressForm'} part in my directive or the controller's $scope.form?

Utilizing the scope property allows you to specify which $scope variables should be passed to the directive and the type of data-binding.

If you wish to create a nested structure within the directive's $scope, you can achieve this within the directive's controller function.

For example:

angular.module('myAddress').directive('myAddress', [function () {
return {
    restrict: 'AE',
    controller: 'myAddressController',
    templateUrl: 'my-address.html',
    scope: {
            addressForm: '=',  // Two-way databinding
            addressModel: '='
    },
    controller: function($scope){
         $scope.address = {
            form: $scope.addressForm,
            model: $scope.addressModel
         }
    },
    link: function($scope,$element,$attributes){
           //Your code here
    }
  };
}]);

Alternatively, you can define $scope.address in the module controller's scope. In such cases, the scope property in the directive should be configured like this:

scope: { 
       address: '='
}

UPDATE:

Another consideration is: Does your directive require its own scope? If not, you can set the scope property to false. This way, your directive will have access to the $scope variables in your module controller.
