Controller not returning data from factory


Controller not returning data from factory

To fix this issue Imagine a prison with prisoners in separate cells, and I want to be able to be able to access a specific cell by calling the API '/getparameters' that will return the cell number, and then pass that variable in as the id for my factory. This is what I have come up with. No error are returned, but no data is being returned either. Where am I going wrong? , You've got your parentheses in the wrong places:
code :
CellID.get({id:cellnumber}), function(data){
    $scope.info = data;
}
CellID.get({id:cellnumber}/* <-- no parenthesis here */, function(data){
    $scope.info = data;
}); // <-- parenthesis here (and a semicolon)
$scope.info = CellID.get({id:cellnumber});

wish helps you Unfortunately, the best solution I found was to revert from Asp.net MVC 4 to Asp.net MVC 3, in which the Ninject.Web.MVC assembly completely handles all of this for you.
Though this may be an unacceptable answer for some, it helped solve my issue.

I think the issue was by ths following , You can update Products.details.current directly from your getProducts function. If getProduct can be called from different places in your app and you want to keep the info in sync within your controller, you can use a $watch.
code :
app
    .factory('Products', function($http, ENV){
        var Products = {};

        Products.details =
        {
            //grabs the most current endpoint and creates a session of that data
            current: {},
            getProduct: function($scope, productId) {
                return $http.get(ENV.apiEndpoint + '/v2/listings/' + productId + '.json')
                    .success(function(data){
                        Products.details.current = data; // Update 
                        return data;
                    })
                    .error(function(data, status){
                        console.log('error:' + status);
                    });
            }

        };

        return Products;
    })

    .controller('MainCtrl', function($scope, Products) {
        $scope.product = Products.details.current;
        var handleProductSuccess = function (data) { // (not required if you use the watch below)

            // stores the data for the current controller

            $scope.product = data;
        };
        //on click of a product from view
        Products.details.getProduct($scope, $scope.productId)
            .success(handleProductSuccess);


        // If another scope can modify Products.details.current and you want to watch for it:
        $scope.$watch(
            function () { return Products.details.current;},
            function (newVal) { $scope.product = newVal; },
            true
        );
    });

this will help Your service method socket.switchSpace() does not return a promise (or, as you have implemented it in your controller, an object with a $promise property).
So in order to make this work, you need to:
code :
.factory('socket', function (socketFactory, $q) {

  var connection = io.connect('http://example.com:3000');

  var socket = socketFactory({
    ioSocket: connection
  });

  socket.switchSpace = function(spaces) {
    var deferred = $q.defer();

    socket.emit('leaveSpace', spaces.oldspace, function(callback) {
      if(callback == 'success') {
        socket.emit('joinSpace', spaces.newspace, function(callback) {
          if(callback == 'success') {
            deferred.resolve(callback);
          }
        })
      }
    });

    return deferred.promise;
  }

  return socket;
});
.controller('SettingsCtrl1', function($scope,socket) {
    socket.switchSpace(spaces).then(function(data) {
      alert("CALLBACK: " + data);
    });
});

hope this fix your issue u can catch the promise from controller instead of the factory. just return the jsonQueryStations.stationData() only in factory.
code :
mainApp.factory('statusFinder', ['jsonQueryStations', 'timeConverter', function(jsonQueryStations, timeConverter){
   var generator = function(){
      return jsonQueryStations.stationData()
   }
   return {
    status: function(){
      return generator();
    }
   }
}])
mainApp.controller('stuff', ['$scope', 'statusFinder', function($scope, statusFinder) {
    var findTheTime = timeConverter.getTime();
    statusFinder.status().then(function(result) {
        if (result.station[findTheTime] > result.station.Average) {
            $scope.testing = "Station is busy";
        } else {
            $scope.testing = "Station is quiet";
        }
    });
}])

I wish did fix the issue. Use below syntax in controller. The reason your code not working is you have written a service called Users.activeDeactive, you are calling it from the controller but not waiting for the response. Its very important to wait for the response. If the service call is successful, it will execute then part. Here you need to catch the response like in given syntax only. In case of errors, it will go to the error part.
code :
    ;(() => {
    app.controller('UsersCtrl', usersCtrl);

    function usersCtrl($scope, $state, Users, users, vendors, profiles, clients) {
       Users.users = users;
    .....
       $scope.activeDeactive = function(userId, activate) {
          Users.activeDeactive(userId, activate).then(function(data){
      response = data;
console.log(response);
   },
   function(error){
       console.log(error);
   });

    .....

   };
})();
