Angularjs: Get data response from server using custom action resource

Question

i am trying to get the response from the server which returns something like true, false, or something else, depending on the request i do, the application i am developing is using a Restful server i created, and just for testing purposes i made it return true or false, later i will make it return proper json data.

here i am trying to get the response from this code (i am not sure how to use promises yet)

app.service('UserService', ['$resource', function($resource){
    var self = this;

    self.login = function(credentials){
        var handler = $resource('server/web/user/access', null, {
            access: {
                method: 'POST'
            }
        });

        handler.access(credentials).$promise.then(function(data){
            console.log(data);
        });
    }
}]);

for now i am just logging what it seems to return from the server, but the log shows another promise. for now i just need to get the data so i can make the conditions, parse objects, or show data it returns from the Restful server

I doubt the data is a promise, it should be a $resource instance. Perhaps you're mistaking it for a promise due to the $promise / $resolved properties it will have. See the bottom of the Usage / Returns section here ~ docs.angularjs.org/api/ngResource/service/$resource#usage — Phil

I'm guessing the problem here is that the $resource service expects either an object or array in the response and your simple Boolean value is not working correctly.

For now, you can use a response transformer to create a usable object

var self = this,
    handler = $resource('server/web/user/access', null, {
        access: {
            method: 'POST',
            transformResponse: function(val) {
                return {
                    val: val
                };
            }
        }
    });

self.login = function(credentials) {
    var promise = handler.access(credentials).$promise;
    promise.then(function(data) {
        $log.info(data.val);
    });
    return promise;
};
