model.fetch.then

[godlark]

Recently I've made code similiar to:

book.fetch().then(function(resp) {
});

And I've expected to get a parsed response with my 'Book.parse' function but I've got a raw response.

Closing in favor of #3729 and #3651. Please do a search before opening issues.

Have you read the issue before closing? My pull request complain about how fetch function works. I DO NOT complain about using jquery.Deffered etc. And my change: only few lines and some changes in tests - there is no a BIG refactor.

Backbone.sync proxies to Backbone.ajax behind the scenes. The then function you're getting from the return value of fetch is simply the return value from jQuery.ajax, a jqxhr (xhr wrapped in jQuery.Deferred.)

Backbone has no use for Promises at the moment. We don't even guarantee that the fetch function will return a thenable (i.e. a function with a then method) as your change requires, therefore we can't add add this change until we make some major plumbing decisions like the ones in #3729 and #3651. If you want this change, stop by those issues and register your input, they might have already added it.

Ok, thanks for the reply :)
