javascript - AngularJS (Material) - Refreshing data in md-list after adding new object using md-dialog -


i'm new whole angular world, yesterday ran problem cannot seem fix. prototype i'm creating simple task application enables user create, view , delete tasks. new task can created clicking button opens dialog. information can given in , clicking "add task" task gets added database.

the problem is, after dialog closes md-list, displays list of items, not refresh show newly added task. did try using "tack by" option ng-repeat, did not work.

i got information question: http://stackoverflow.com/questions/27874976/update-a-md-list-dynamically-from-angular

the code i'm using display tasks 1 (simplified)

<html lang="en" ng-app="taskapp"> <head></head> <body>     <div ng-controller="taskcontroller">         <md-list>             <md-list-item ng-repeat="task in tasks track task.id">                 <md-checkbox ng-model="task.checked" ng-change="updatetask(task)" aria-label="complete task"></md-checkbox>                 <p>{{ task.title }}</p>             </md-list-item>         </md-list>     </div> </body> </html>

the template dialog looks this:

<md-dialog aria-label="create new task">     <md-content>         <md-card class="card-padding">             <form ng-submit="addtask(newtitle)">                 <h2 class="md-title">add new task</h2>                 <div layout="row">                     <md-input-container flex>                         <label>title</label>                         <input ng-model="newtitle">                     </md-input-container>                 </div>                 <div layout="row">                     <md-input-container flex>                         <md-button class="md-raised md-primary" type="submit" ng-disabled="!newtitle || !newdescription">add task</md-button>                     </md-input-container>                 </div>             </form>         </md-card>     </md-content> </md-dialog>

and controller looks this:

(function(angular) {     var taskcontroller = function($scope, $mddialog, task) {         task.query(function(response) {             $scope.tasks = response ? response : [];         });          $scope.addtask = function(title) {             new task({                 title: title,                 checked: false             }).$save(function(task) {                 $scope.tasks.push(task);             });             $scope.newtitle = "";             $mddialog.hide();         };          $scope.showdialog = function(ev) {             $mddialog.show({                 controller: taskcontroller,                 templateurl: 'taskdialog.tmpl.html',                 parent: angular.element(document.body),                 targetevent: ev,             });         };          $scope.updatetask = function(task) {             task.$update();         };          $scope.deletetask = function(task) {             task.$remove(function() {                 $scope.tasks.splice($scope.tasks.indexof(task), 1);             });         };     };      taskcontroller.$inject = ['$scope', '$mddialog', 'task'];     angular.module("taskapp.controllers").controller("taskcontroller", taskcontroller); }(angular));

so wondering if me problem.
in advance!

you pushing task tasks list in wrong scope.

following should work you. while showing dialog.

$mddialog.show({   controller: taskcontroller,   templateurl: 'taskdialog.tmpl.html',   parent: angular.element(document.body),   targetevent: ev, }).then(function(task){   $scope.tasks.push(task); });

while hiding dialog.

$mddialog.hide(task);
