ngModel' deep objects creation mechanism

Question

I want to use angular' mechanism for deep property nesting , something that ng-model directive is using. I mean we can create very "deep" object in a scope by writing : ng-model="data.obj1.prop2.attr3.value4.text" in a view , so i want to do it easily in a controller/service too. I don't want to reinvent a wheel (or use this or this). Is there something undocumented like angular.create(path_str) ?

One way you can achieve is by using $parse service. It has getter and setter function that i think can handle what you want

    var getter = $parse('prop1.prop2.prop3.prop4');
    var setter = getter.assign;
    setter($scope,"value1111");

See this fiddle http://jsfiddle.net/cmyworld/m7gxn/

And i think this also works

$scope.$eval("prop2.prop2.prop3.prop4=55");
