Restangular put loses part of the url

Question

I want to modify one object via a REST API using Restangular on the client side. I do the following:

Restangular.setBaseUrl('/api/v1');
return Restangular.one('lists', item.listId).one('items',item.order).get().then(function(elem) {
    elem.text = item.text;
    elem.put();
});

But the put method gets the wrong URL missing the ID for the last member (item.order).

The expected url is /lists/2/items/22 but i get /lists/2/items and the PUT fails.

What could I be doing wrong?

Ok, let me try a theory :)

My comment above was a bit lame because I was focusing on the first part of the code and not the put().

The first part is perfect, you tell Restangular to build the URL with one() methods and the GET request must be very fine.

Then, base on a new Restangular-aware object, you try to persist the change in your API. However, I believe that Restangular does not actually know what field to use as id in order to build the right query for your elem object.

Did you try to configure, in your Restangular Entity Provider the fields property?

RestangularProvider.setRestangularFields({
   id: "orderId",
});

I believe that specifying the right field as id would suffice.

As a bonus, it seems that .save() will use PUT or POST accordingly if it's a new object or not.

Hope this helps
