在angularJS的每次迭代中保存for循环内部？

Question

我尝试在for循环中向DB添加元素。只有一个进入DB然后我得到500（内部服务器错误）重复密钥。奇怪的是，在javaScript日志中我连续有两个reasonList对象，之后它会保存并尝试保存同一个对象的两倍，最后一个。

Glassfish错误日志

com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Duplicate entry '4-3-6' for key 'PRIMARY'

在控制器中我尝试同时保存rma和reasonList

savedRma = rmaService.save({}, rma);
savedRma.$promise.then(function (result) {
    $scope.rma = result;
    console.log('result.rmaID--------->'+ result.rmaId);
    for (var i = 0; i < $scope.reasonList.length; i++) {
        $scope.rmaHasDefectdesc.rmaHasDefectdescPK.defectdescDefectdescId = reasonList[i].defectdescId;
        $scope.rmaHasDefectdesc.rmaHasDefectdescPK.returnreasonId = reasonList[i].returnreasonReturnreasonId.returnreasonId;
        $scope.rmaHasDefectdesc.rmaHasDefectdescPK.rmaId = $scope.rma.rmaId;

        console.log('defectDescID: ' +reasonList[i].defectdescId);
        console.log('returnReasonID: ' +reasonList[i].returnreasonReturnreasonId.returnreasonId)
        console.log('rmaID: ' +$scope.rma.rmaId);

        savedRmaHasDefectdesc = rmaDefectSvc.save({}, $scope.rmaHasDefectdesc);
        savedRmaHasDefectdesc.$promise.then(function (response) {
            $scope.savedRmaHasDefectdesc = response;
            console.log('response.rmaHasDefectdescPK--------->'+ response.rmaHasDefectdescPK.defectdescDefectdescId);
            console.log('response.rmaHasDefectdescPK.returnreasonId--------->'+ response.rmaHasDefectdescPK.returnreasonId);
            console.log('response.rmaHasDefectdescPK.rmaId--------->'+ response.rmaHasDefectdescPK.rmaId);
        });
  } //FOR LOOP ENDS   
});//savedRma.promise.then ENDS
