AngularJS中update两次出现$promise属性无法识别的解决方法

前言

本文主要介绍的是在AngularJS中update两次出现$promise属性无法识别的解决方法，下面话不多说，先来看看错误提示，然后再看看解决的办法吧。

一、错误信息如下：

ERROR 2015-12-02 14:33:17,653 http-bio-8080-exec-42 o.s.s.r.i.e.InternalErrorExceptionMapper - Unrecognized field "$promise" (class com.inetpsa.fnd.rest.client.ClientRepresentation), not marked as ignorable (6 known properties: "lastName", "address", "telephone", "clientId", "mail", "firstName"])

二、问题代码

Angular 自动会在返回的data数据中带上$promise属性。

在进行下面copy时将从data返回的数据copy到当前行用来显示，这样在进行update的操作时带的数据体中就包含了$promise属性，结果就会出现上述错误导致update失败。  

三、更改如下：

// ===============show the update modal dialog ================== 
 $scope.tempRowEntityForUpdate; 
 $scope.openUpdateClientPopup=function(){ 
 $scope.form1.$setSubmitted(true); 
 $scope.tempRowEntityForUpdate = {}; 
 angular.copy($scope.currentSelectedRowEntity, $scope.tempRowEntityForUpdate); 
 angular.element('#UpdateDialog').modal({ 
 backdrop: false 
 }); 
 
 }; 
 
 $scope.updateClient=function(){ 
 if($scope.form1.$submitted && $scope.form1.$valid){ 
 Client.update({},$scope.tempRowEntityForUpdate,function(){ 
  angular.copy($scope.tempRowEntityForUpdate,$scope.currentSelectedRowEntity); 
 }); 
 
 angular.element('#UpdateDialog').modal('hide'); 
 } 
 };

解决办法：不使用更新后获得的data数据，而是从当前的行模型中取得数据copy给当前选中的行即可。
