'how to properly use angular-file-upload on a page

I need to use angular-file-upload directive (https://github.com/nervgh/angular-file-upload).

I took the html as well as the controller example as-is from github:

html:

<body ng-controller="GeekController" nv-file-drop="" uploader="uploader" filters="queueLimit, customFilter">
<div class="container">
    <div class="navbar navbar-default">
        <div class="navbar-header">
            <a class="navbar-brand" href="https://github.com/nervgh/angular-file-upload">Angular File Upload</a>
        </div>
        <div class="navbar-collapse collapse">
            <ul class="nav navbar-nav">
                <li class="active dropdown">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">Demos <b class="caret"></b></a>
                    <ul class="dropdown-menu">
                        <li class="active"><a href="#">Simple example</a></li>

Controller:

angular.module('GeekCtrl', ['angularFileUpload'])
    .controller('GeekController', ['$scope', 'FileUploader', function($scope, FileUploader) {
        var uploader = $scope.uploader = new FileUploader({
            url: 'upload.php'
        });
// FILTERS
        uploader.filters.push({
            name: 'customFilter',
            fn: function(item /*{File|FileLikeObject}*/, options) {
                return this.queue.length < 10;
            }
        });
// CALLBACKS
        uploader.onWhenAddingFileFailed = function(item /*{File|FileLikeObject}*/, filter, options) {
            console.info('onWhenAddingFileFailed', item, filter, options);
        };
        uploader.onAfterAddingFile = function(fileItem) {
            console.info('onAfterAddingFile', fileItem);
        };
        uploader.onAfterAddingAll = function(addedFileItems) {
            console.info('onAfterAddingAll', addedFileItems);
        };
        uploader.onBeforeUploadItem = function(item) {
            console.info('onBeforeUploadItem', item);
        };
        uploader.onProgressItem = function(fileItem, progress) {
            console.info('onProgressItem', fileItem, progress);
        };
        uploader.onProgressAll = function(progress) {
            console.info('onProgressAll', progress);
        };
        uploader.onSuccessItem = function(fileItem, response, status, headers) {
            console.info('onSuccessItem', fileItem, response, status, headers);
        };
        uploader.onErrorItem = function(fileItem, response, status, headers) {
            console.info('onErrorItem', fileItem, response, status, headers);
        };
        uploader.onCancelItem = function(fileItem, response, status, headers) {
            console.info('onCancelItem', fileItem, response, status, headers);
        };
        uploader.onCompleteItem = function(fileItem, response, status, headers) {
            console.info('onCompleteItem', fileItem, response, status, headers);
        };
        uploader.onCompleteAll = function() {
            console.info('onCompleteAll');
        };
        console.info('uploader', uploader);
    }]);

When I run this, I get the following error:

" "<div class="well my-drop-zone" nv-file-over="" uploader="uploader">"

What do I need to change to make this work properly?

Solution 1:^[1]

In html use {{uploader}} to acces the uploader of the controller or alternatively do a $scope.uploader= new FileUplader(...) in the controller

Solution 2:^[2]

this is similiar to "Uploader" must be an instance of FileUploader

You can use the directive ng-if in your div

<div class="well my-drop-zone" ng-if="uploader" nv-file-over="" uploader="uploader">
