Asynchronous task in response interceptor?

[jpetitcolas]

I am currently trying to implement ng-admin with a Loopback API. As Loopback provides collection length in a separate route (/api/cars/count), I would like to decorate the response with a totalCount property retrieved from this URL.

Here is what I've done so far:

app.run(['Restangular', '$http', function(RestangularProvider, $http) {
    RestangularProvider.addResponseInterceptor(function(data, operation, what, url, response, deferred) {
        if (operation !== 'getList') {
            deferred.resolve(data);
        }

        $http.get(url + '/count')
            .success(function(countData) {
                response.totalCount = countData.count;
                deferred.resolve(data);
            })
            .error(function(error) {
                deferred.reject(error);
            });
    });
}]);

Does Restangular interceptor deals correctly with asynchronous tasks?

Probably related to #893.

Bump! :)

Seems that response interceptor can not return promise currently. When I do for the getList method, I get the Response for getList SHOULD be an array and not an object or something else error message.

Need this to handle compaction of jsonld, when context is an URI.
