Issue: [ng:areq] The parameter 'TasksCtrl' should be a function, but it is currently undefined

I seem to be encountering an error and I'm struggling to identify the cause. Is there something I overlooked?

js

var app = angular.module('Todolist', []);

app.controller('TasksCtrl', [
  '$scope', function($scope) {
    $scope.tasks = Task.query({
      status: 'incompleted'
    });

   $scope.completed_tasks = Task.query({
     status: 'completed'
    });

 }
]);

html

<div ng-controller='TasksCtrl' class='tasks-container'>
</div>

Answer №1

Ensure to include the Task service dependency in your controller.

Controller

app.controller('TasksCtrl', [
  '$scope', 'Task', function($scope, Task) {
    $scope.tasks = Task.query({
      status: 'incompleted'
    });

   $scope.completed_tasks = Task.query({
     status: 'completed'
    });

 }
]);

Make sure that the Task service is defined somewhere in your code before using it.

Edit

In addition to solving your other issue, check for any duplicate app declarations when defining services. This can cause the error

Error: [ng:areq] Argument 'TasksCtrl' is not a function
.
