我非常擅长角度并将数据保存到数据库然后检索它。我正在使用Angular Material作为我的依赖项之一。
在第一步中，我成功创建了一个用户（保存到db），然后通过列表上的ng-repeat检索它。最后删除用户。
现在我想要做同样的事情，然后在我的表单中创建一些包含更多输入字段的任务。在这里，我遇到了几个问题：
表单位于对话框中（md-dialog - ＆gt; angular material）（同样用于创建用户）
HTML code：
<body ng-controller="AppCtrl">
<div class="tile contentEditorBox" ng-dblclick="showPopUp($event)" ce-drag ce-resize ng-repeat="task in taskInfo"
style="top: {{ gridSizeNG.y * item.row }}px; left: {{ gridSizeNG.x * item.column }}px; width: {{ gridSizeNG.x * item.width }}px; "
ng-data-id="{{ task.id }}" ng-init="snapInit()">
<div class="txtWrapperTile">
<div class="containerTxt">
<div class="taskName">
<h5> {{ task.task_name }} </h5>
</div>
<div class="taskProjectClient">
<!-- <p class="pPC"> {{ task.task_project_client_name}} </p> -->
<p class="pPC"> {{ task.id_Location }} </p>
</div>
</div><!-- end containerTxt -->
</div><!-- end txtWrapperTile -->
</div>
</body>
