How to fix foreach forEach is not a function

am quite new to programming and my app is returning an error when I do a forEach function. I have the following code in my controller.js 

$scope.ajaxRequest = A.Game.get({action: 'game',id: user.id});
          $scope.ajaxRequest.$promise.then(function(){                                      
                $scope.ajaxRequest.game.forEach(function(entry) {
                    if(cards.indexOf(entry) !== -1) {
                        console.log('alredy in game');
                    } else {
                        if(entry.id != user.id){
                            cards.push(entry);                                
                            $scope.imageLocations.push(entry.photo);
                        }
                    }
                });

My console is giving me this error 

ionic.bundle.js:26799 TypeError: $scope.ajaxRequest.game.forEach is not a function

This

          $scope.ajaxRequest.$promise.then(function(){                                      
                $scope.ajaxRequest.game.forEach(function(entry) {

looks fishy. Change it to

          $scope.ajaxRequest.$promise.then(function(result) {                                      
                result.forEach(function(entry) {

Now, I won't guarantee without seeing the result that it'll work, but this is the pattern of working with asynchronous calls and promises: in the .then block, put a function that uses the output of the previous one in the promise chain as argument. So at least this change

          $scope.ajaxRequest.$promise.then(function(result) {

(instead of $scope.ajaxRequest.$promise.then(function() {) is necessary.
