Restangular - Specific Function to Specific Factory - angularjs

Question

I'm working with restangular and so far, everything works very well, but, i have this issue that cannot resolve.
I define a abstract repository with the basic operations like this:
app.factory('AbstractRepository', [
function(){
function AbstractRepository(restangular, route) {
this.restangular = restangular;
this.route = route;
};
AbstractRepository.prototype = {
getList: function (params) {
return this.restangular.all(this.route).getList(params).$object;
},
get: function (id) {
return this.restangular.one(this.route, id).get();
},
getView: function (id) {
return this.restangular.one(this.route, id).one(this.route + 'view').get();
},
update: function (updatedResource) {
return updatedResource.put().$object;
},
create: function (newResource) {
return this.restangular.all(this.route).post(newResource);
},
remove: function (object) {
return this.restangular.one(this.route, object.id).remove();
},
};
AbstractRepository.extend = function (repository) {
repository.prototype = Object.create(AbstractRepository.prototype);
repository.prototype.constructor = repository;
}
return AbstractRepository;
}
]);
And the specific respository:
app.factory('ServiceRepository', ['Restangular', 'AbstractRepository',
function (restangular, AbstractRepository) {
function ServiceRepository() {
//restangular.setBaseUrl("http://192.168.0.144:8080/api/rest/services/");
AbstractRepository.call(this, restangular,'http://192.168.0.144:8080/api/rest/services/');
}
AbstractRepository.extend(ServiceRepository);
return new ServiceRepository();
}
And i call the methods :
ServiceRepository.getList();
And now i want to implement and function (getServicesByOperatorId) that only works in the specific repository, not in the abstract. So i can call it like this:
ServiceRepository.getServicesByOperatorId({"operatorId":7});
If i define the function in the prototype of the abstract it works, but i want i way to define in the specific.
Thank you very much for your time.

Answer 1

Finally i find a way to do what i want:
In the specific factory define the prototype and extend from the abstract prototype like this:
ServiceRepository.prototype = {
getServicesByOperatorId: function (id) {
return this.restangular.all(this.route + 'getServicesByOperatorId').getList(id).$object;
}
}
angular.extend(ServiceRepository.prototype, AbstractRepository.prototype);
And in the abstract repository, remove this definition:
AbstractRepository.extend = function (repository) {
repository.prototype = Object.create(AbstractRepository.prototype);
repository.prototype.constructor = repository;
}
No i can access to de getList() method and the getServicesByOperatorId().
