角$ update资源

Question

EDIT: If it's difficult to troubleshoot without me posting more code, let me know and I can add more to the question.

---

I have two instances of basically the same code, and one of them is working while the other isn't.

Working fine:

$scope.update = function() {
  var question = $scope.question;
  question.$update(function() {
    $location.path('questions/' + question._id);
  });
};

Not working:

$scope.updateAnswer = function() {
  var answer = $scope.answerEdited;
  answer.$update(function() {
    $location.path('questions/' + $routeParams.questionId);
  });

  $scope.toggleEditAnswer(answer);
};

I get the error: undefined is not a function at my $update function. Here's my resource:

angular.module('intquestApp')
  .factory('Answers', function ($resource) {
    return $resource('api/answers/:answerId', {
      answerId: '@_id'
    }, {
      update: {
        method: 'PUT'
      }
    });
  });

What exactly am I doing wrong? If I understand the flow correctly, the answer.$update uses the resource somehow? Also, if I use console.log to view what answer is being updated, it is the correct one:

Resource {_id: "543d8896039390eb5e000001", created: "2014-10-14T20:33:26.514Z", creator: Object, questionid: "543d8693994fc1685d000001", __v: 0…}

How exactly can I troubleshoot this?

Answer 1

Could you try the following and check if it works?

$scope.updateAnswer = function() {
    Answers.update($scope.answerEdited, function(response) {
        $location.path('questions/' + $routeParams.questionId);
    });

    $scope.toggleEditAnswer(answer);
};
