Upload multiple files in angular

I've a situation where I've a form in which I've a row where I've two text fields entries and I've to upload a file for that row and this kind of rows can be 'N' and then there is a master files that can be entered for whole form while these are some part of the form and I've to submit all these files at once on clicking a save button.

I'm kind of stuck with ng-upload it needs an api call, and I really can't have more than one api call for this form. The sample html code is below :

<!DOCTYPE html>
<html>

<head>
  <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>

<body>

  <form editable-form name="xyzForm" ng-submit="create(model)">
    <label>Tags: </label><input class="col-xs-12 col-md-12" ng-model="model.tags" type="text" name="Tags">
    <label>Notes: </label> <input class="col-xs-12 col-md-11" ng-model="model.notes" type="text" name="notes">
    <table class=" col-xs-3 col-md-11 table" border="1px solid red;">
      <thead>
        <tr>
          <th>Product</th>
          <th>Manufacturer</th>
          <th>Location</th>
          <th>Specification</th>
          <th></th>
        </tr>
      </thead>
      <tbody>
        <tr ng-repeat="itemRow in item.singleItem">
          <td><input type="text" class="xdTextBox" name="itemRow.name" ng-model="model.itemRow[$index].name" /></td>
          <td><input type="text" class="xdTextBox" name="itemRow.manufacturer" ng-model="model.itemRow[$index].manufacturer" /></td>
          <td><input type="text" class="xdTextBox" name="itemRow.location" ng-model="model.itemRow[$index].location" /></td>
          <td><i class="pull-left glyphicon glyphicon-upload"><input type="file" name="itemRow.doc" ng-model="model.itemRow[$index].doc" multiple=false></i></td>
          <td><i class="pull-left glyphicon glyphicon-remove"></i></td>
        </tr>

      </tbody>
      </span>
    </table>

    <label>Product Spec: </label><input type="file" ng-model="prefabdoc" multiple="true" ngf-maxsize="15000000" />
  </form>

</body>

</html>

from saltuk's answer above there is a small change for the code to work

    var modelSetter = model.assign;
        element.bind('change', function () {
            var values = [];
            angular.forEach(element[0].files, function (item) {
                var value = {...
                }
            }
        }

the array var should be defined above before forEach function

    var modelSetter = model.assign;
    element.bind('change', function () {
        var values = [];
        angular.forEach(element[0].files, function (item) {
            var value = {...
            }
        }
    }

If you don't care about browsers less than IE 9. Then you can follow this post and construct a FormData object in your ng-submit event. This will create a form/multipart and might not be what your looking for but it does the trick.

Here is file value binding directive example ..

http://plnkr.co/edit/B13t84j5IPzINMh1F862?p=preview

Js code is:

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

app.controller('MainCtrl', function($scope) {
  $scope.name = 'World';
  $scope.files = []; 
  $scope.upload=function(){
    alert($scope.files.length+" files selected ... Write your Upload Code"); 

  };
});


app.directive('ngFileModel', ['$parse', function ($parse) {
    return {
        restrict: 'A',
        link: function (scope, element, attrs) {
            var model = $parse(attrs.ngFileModel);
            var isMultiple = attrs.multiple;
            var modelSetter = model.assign;
            element.bind('change', function () {
                var values = [];
                angular.forEach(element[0].files, function (item) {
                    var value = {
                       // File Name 
                        name: item.name,
                        //File Size 
                        size: item.size,
                        //File URL to view 
                        url: URL.createObjectURL(item),
                        // File Input Value 
                        _file: item
                    };
                    values.push(value);
                });
                scope.$apply(function () {
                    if (isMultiple) {
                        modelSetter(scope, values);
                    } else {
                        modelSetter(scope, values[0]);
                    }
                });
            });
        }
    };
}]);

Html Code is:

<!DOCTYPE html>
<html ng-app="myApp">

  <head>
    <meta charset="utf-8" />
    <title>AngularJS Plunker</title>
    <script>document.write('<base href="' + document.location + '" />');</script>
    <link href="style.css" rel="stylesheet" />
    <script data-semver="1.4.3" src="https://code.angularjs.org/1.4.3/angular.js" 
        data-require="angular.js@1.4.x"></script>
    <script src="app.js"></script>
  </head>

  <body ng-controller="MainCtrl">
    <p>Hello {{name}}!</p>
    <input type="file" ng-file-model="files" multiple />
    <button type="button" ng-click="upload()">Upload</button>

    <p ng-repeat="file in files">
      {{file.name}}
    </p>
  </body>

</html>
