Alternative to using ng-init in 'view'?

Question

I am trying to create a \'like\' function for my app. I want to be able to set the value of a dynamically generated number as the \'like count\'. The problem comes in using \'ng

Answer 1

Just change

`{{likeCount}}`

per

`{{feed.likes.length}}`.

If you still need the count in the controller for some other reason (which I can't see), create a controller, let's assume FeedCtrl, and add it to your article:

  ...
  {{likeCount}}

And your FeedCtrl would be:

function FeedCtrl($scope) {
  $scope.$watch('feed.likes.length', function(newValue) {
    $scope.likeCount = newValue;
  });
}

Yet another approach would be create a function to resolve you the value:

  ...
  {{likeCount()}}

function FeedCtrl($scope) {
  $scope.likeCount = function() {
    return $feed && $feed.likes ? $feed.likes.length : undefined;
  };
}
