.controller('DishDetailController', ['$scope', function($scope) {
    var dish={

        category: 'mains', 
        label:'Hot',

            }
        ]
    };
    $scope.dish = dish;
}])
.controller('DishCommentController', ['$scope', function($scope) {
    $scope.newcomment = {
        rating : "",
        comment: "",
        author: "",
        date: new Date().toISOString()
    };
    $scope.submitComment = function () {
        $scope.newcomment.date = new Date().toISOString();
        $scope.newcomment.rating = parseInt($scope.newcomment.rating)
        console.log($scope.newcomment.comment);
        console.log($scope.newcomment.author);
        console.log($scope.newcomment.rating);
        console.log($scope.newcomment.date);
        $scope.dish.comments.push($scope.newcomment);
    }
}]);

In html part part I have only two-three textbox. SubmitComment in button onclick. Console.log show me the result which I need. But I cannot push this to array. The exercise is a part of tutorial. So it was requirement to write them in seperate controllers and this was provided by the tutorial

Answer 1

The dish object is not defined in the second controller which make sense from the error "undefined". You have to find a way to pass the dish object from the first controller "DishDetailController" to the second one "DishCommentController". There are several ways to do it, one way is to stock the object into service from the first controller then retrieve it from the same service in the second controller. As I know the best way to share objects between controlllers is via services.
