custom method for all models, regardless of route or loaded state

[terebentina]

Hi,

Is there a way to have something like this:

var form = Restangular.one('notes');
form.id = 1;
form.title = 'bla';
form.save();

Where save() is a custom function, defined for all models (not just for notes) which simply does something like the following?

function save() {
    if (this.id) {
        this.put();
    } else {
        this.post();
    }
}

Basically my question is how/where can I define a function like this save()?

To add to the above, this is how I currently do it:

RestangularProvider.extendModel('notes', function(note) {
    note.save = function() {
        if (note._id) {
            return note.put();
        } else {
            return note.post();
        }
    };
    return note;
});

Same for all other models, resulting in a lot of copy&paste of the same code. I'd like do define that save function in a single place for all....

If you need it for all models, you can just use the generic onElemRestangularized

RestangularProvider. setOnElemRestangularized(function(elem, isCollection, what) {
  elem.myMethod = function() {};
});

With this, myMethod would be added to ALL elements, either if they're collections or not. You can use isCollection to filter by wether a collection or element is to which you're adding this function and the what is the route (Notes for example).

With this, you can make it in just one place for all of them :)

Ah, ok. I kind of tried to follow the advice of using addElementTransformer and couldn't figure out how to do it with that. And when I tried to look up an example using onElemRestangularized, I couldn't find one. I think the onElemRestangularized docs could use a sentence like "Use this to add your custom methods and properties to elements", or a FAQ/example for onElemRestangularized based on this very issue: how to add a .save() method to all models or something.

[mgonto]

You could use the onElemRestangularized for whatever you need. It's called after EVERY element has been restangularized.

Do you need extra help getting it to work?

No, absolutely not, thank you. Once you pointed me in the right direction, everything was a breeze. I just commented to let you know that I found the docs a bit foggy and to offer my suggestion of improvement.
