What is the error when initializing angularFileUpload?

Question

Angular

Hello. I continue to learn angular. I can not deal with the file uploader to the server.
here is the input:

<input type="file" id="slider_photo" name="slider[photo]" required="required" class="form-control" nv-file-select="" uploader="uploader">

js

var adminControllers = angular.module('adminControllers',['angularFileUpload']);


adminControllers.controller('AddPageCtrl',['$scope', '$http', '$route', '$location', '$templateCache' , 'FileUploader',
    function($scope, $http,$route,$location, $templateCache, FileUploader){

        var uploader = $scope.uploader = new FileUploader({
            url: 'upload.php'
        });

    }
]);

Such an error flies out

What could be the matter?
Thank you.

Answer 1

var uploader = $scope.uploader = new FileUploader({
            url: 'upload.php'
        });

Remove the variable, and the scope is enough for you.
