Unable to retrieve injected AngularJS services when inside a function within a controller

The $scope and Food variables are inaccessible within the destroy function.

foodProject.controller('FoodsCtrl', function($scope, Food) {

    $scope.foods = Food.index();
    $scope.destroy = function(food){
        debugger;
        console.log(Food, $scope);
        food.$destroy();
    };
});

Only the following local scope variables are available:

food: Resource

this: $get.e.$new.a

I cannot locate $scope and Food

Answer №1

Make sure to add the following line to your destroy function (which is currently missing from your code sandbox):

console.log(Food, $scope);

While debugging, take a look at the Closure section of Scope Variables (I usually use Chrome) when you reach your break point. You should see Food and $scope listed there as expected.

The context of this in the destroy function pertains to a new scope within ng-repeat, so it differs from the $scope, even though they are both scopes.

Answer №2

When working within your function, the scope of this is crucial, as seen in examples like this.dogs.

In my perspective, if you wish for access to Dog, consider including it in the scope by doing something like $scope.Dog = Dog;.

As a beginner, I'm uncertain whether adding Dog to $scope is the most appropriate approach.
