Question

我正在学习棱角分明和弹簧。我有一个列表屏幕，我使用角度ui网格。在列表屏幕中，可以通过单击按钮和弹出窗口添加新记录。现在，当用户通过弹出窗口添加记录时，即使记录成功保存在数据库中，它也没有反映在网格中。有人可以指导我在数据库保存后将记录推送到网格吗？

1，我认为你有一个拼写错误的问题：

在您的VehicleMgmntController控制器中，从服务器返回的数据存储在：

$ scope.vehicleGrid.data = result;

但是在你的模态中，你想在vehicleGrid中推送一些东西，其中包含网格的设置数据而不是数据源。

$scope.save = function() {
      $scope.isSaving = true;
      /*if ($scope.user.id != null) {
          User.update($scope.user, onSaveSuccess, onSaveError);
      } else {*/
      Vehicle.save($scope.vehicle, onSaveSuccess, onSaveError);
      $scope.$parent.vehicleGrid.push(vehicle);
      //try this:
      $scope.$parent.vehicleGrid.data.push(vehicle);          
      // }

    };

我认为车辆服务会返回新添加的车辆，对吗？

2，我有一种感觉，你onSveSuccess的运行时间晚于你的Vehicle.save。您是否考虑过使用.then（）语法来处理promises？

$scope.save = function() {
      $scope.isSaving = true;
      /*if ($scope.user.id != null) {
          User.update($scope.user, onSaveSuccess, onSaveError);
      } else {*/
      Vehicle.save($scope.vehicle).then(function(result) {
             $scope.$parent.vehicleGrid.data.push(vehicle);
      }, function(error){
            //some error handling
      });

      // }

    };

如何自动将新保存的记录添加到ui-grid？
