Javascript 微风不吹'；t识别修改后的实体

我有一个breeze实现，它接受一个location对象并在UI上显示属性。我对一些属性进行了更改并尝试保存更改，但breeze没有将实体识别为已更改。以下是我的代码：

    [HttpGet]
    [CustomAuthorize(Claims = "permission:CanViewLocationAttributes")]
    public Location GetLocationById(int clientId, int locationId)
    {
        //returns a single Location object

    }

以下是检索实体并保存实体的客户端功能：

    function getLocationById(clientId, locationId) {
        var self = this;

        return EntityQuery.from('GetLocationById')
                            .withParameters({ clientId: clientId, locationId : locationId })
                            .using(self.manager)
                            .execute()
                            .then(querySucceeded, this._queryFailed);

        function querySucceeded(data) {
            if (data.results.length > 0) {
                return data.results[0];
            }
            logSuccess(localize.getLocalizedString('_RetrievedLocations_'), locations, true);
        }
    }

        function saveLocationSettings(clientId) {
        var self = this;
        var saveOptions = this.manager.saveOptions.using({ resourceName: "SaveLocationSettings",  allowConcurrentSaves: true });
        var entitiesToSave = self.manager.getChanges();
        return self.manager.saveChanges(entitiesToSave, saveOptions).then(saveSucceeded, saveFailed);
    }

我的问题是这里entitiesToSave的值是0，即使在我更改UI中的字段并保存它们之后也是如此

以下是如何将实体绑定到角度模型：

  function getLocationDetails() {
        clientcontext.location.getLocationById($route.current.params.clientId, $route.current.params.id)
  .then(function (data) {
      basicLocationSettings.id = data.locationId;
      basicLocationSettings.parent = data.fkParentLocationId;
      basicLocationSettings.locationType = data.locationType;
      basicLocationSettings.locationName = data.locationName;
      basicLocationSettings.locationDisplayName = data.locationDisplayName;
      basicLocationSettings.locationCode = data.locationCode;
      basicLocationSettings.isActive = data.activeStatus;
      basicLocationSettings.timeZone = data.fkTimeZoneId;
      basicLocationSettings.usesAppointments = data.usesAppointments;
      basicLocationSettings.availabilityWindowDays = data.availabilityWindowDays;
      basicLocationSettings.appointmentCutOffDays = data.appointmentCutOffDays;
      basicLocationSettings.dailySummaryEmailTime = data.dailySummaryEmailTime;
      basicLocationSettings.reminderBeforeApptEmailTime = data.reminderBeforeApptEmailTime;
      basicLocationSettings.saveLocationSettings = function () {
          clientcontext.location.saveLocationSettings($route.current.params.clientId);
      }
  });
    }

谁能解释我做错了什么？这是我第一次尝试breeze，我有点被困在这里。

看起来您正在将breeze位置实体的属性值复制到名为“basicLocationSettings”的pojo对象变量中。对basicLocationSettings的任何更改都不会被breeze实体管理器跟踪，也不会反映在源breeze实体中。您需要将实际的breeze实体绑定到UI，以便用户数据输入直接修改实体属性值。

我修改了代码，如下所示，现在保存工作正常：

 function getLocationById(clientId, locationId) {
        var self = this;
        var location = null;

        return EntityQuery.from('GetLocationById')
                            .withParameters({ clientId: clientId, locationId : locationId })
                            .using(self.manager)
                            .execute()
                            .then(querySucceeded, this._queryFailed);

        function querySucceeded(data) {
            if (data.results.length > 0) {
                location = data.results[0];
            }
            logSuccess(localize.getLocalizedString('_RetrievedLocations_'), locations, true);
            return location;
        }
    }

注意，我正在返回一个location对象，在我的控制器中，我将location对象绑定到我的POJO

        function getLocationDetails() {
        clientcontext.location.getLocationById($route.current.params.clientId, $route.current.params.id)
  .then(function (data) {
      basicLocationSettings.location = data;
      basicLocationSettings.saveLocationSettings = saveLocationSettings;
  });
    }

现在，当我调用saveChanges（）时，我将location对象传递到存储库：

      function saveLocationSettings() {
        clientcontext.location.saveLocationSettings(basicLocationSettings.location);
    }

但是，难道没有一种方法可以使用某种viewmodel进行UI绑定吗？我的breeze查询运行在一个单独的存储库中，我使用一个单独的控制器与创建pojo对象的UI进行通信。在该设计中，如何将breeze实体直接绑定到UI？这是一个单独的问题，应该在angularjs标记下提出。我会尽力帮忙的，但我对angular没有太多经验。谢谢你的提示，我发现了我做错了什么，并修复了它。我将把答案分开。正如你所说的，不是微风造成了麻烦，而是棱角分明。
