angular get controller constructor

Question

I try to factor out some common functionality between some of my controllers into a parent controller. I'd like to do this using some sort of inheritance, instead of some sort of service. All examples using the $injector.invoke function rely on the parent's constructor function being in scope. Like this: http://plnkr.co/edit/kva82QyytKQfOafGiVxL?p=preview.

Since I have all my controllers in separate files, I'd like to do something like this:

The parent controller has its own module:

angular.module('app.parent').controller('ParentCtrl', function() {
    this.someMethodProvidedbyParent = ....
});

The child controller extends ParentCtrl using $injector.invoke. How to get ParentCtrl?

angular.module('app.parent.child').controller('ChildCtrl', function($injector) {

    // Somehow need to get ParentCtrl from the angular module 'app.parent'
    $injector.invoke(ParentCtrl, this, {});
});

I assume I could just place ParentCtrl in some object on the global scope, but I'd rather use the angular module system.

you could use $controller dependancy, $controller('ParentCtrl', {this: this}); should work in child controller — Pankaj Parkar

Ok I managed to do it with instantiating the parent controller and then using angular.extend like so:

app.controller('ChildCtrl', function($controller) {
  angular.extend(this, $controller('ParentCtrl'));

  // Overriding methods here (after extending `this`)
});

Properties from the parent are copied to this.
