Javascript 如何在连接表时忽略sequelize中的特定外键？

为了弄清楚这件事，我最近几个小时一直在发毛。我正在为

express

应用程序使用

sequelize

orm。

sequelize

doc对我来说非常混乱，我一直在努力寻找解决方案，但到目前为止都没有

我有三个协会

//models/device.js


device.associate = function(models) {
        device.hasMany(models.actuator_activity, {
          foreignKey: 'actuator_device_id',
          as: 'actuator_activities',
        });
        device.hasMany(models.actuator_activity, {
          foreignKey: 'sensor_device_id',
        });
        device.hasMany(models.sensor_data, {
          foreignKey: 'sensor_device_id',
          as: 'sensor_data',
        });
      };




//models/sensordata.js


sensor_data.associate = function(models) {
    sensor_data.belongsTo(models.device, {
      foreignKey: 'sensor_device_id',
      onDelete: 'CASCADE',
    });
  };




//models/actuatoractivity.js


    actuator_activity.associate = function(models) {
        actuator_activity.belongsTo(models.device, {
          foreignKey: 'actuator_device_id',
          onDelete: 'CASCADE',
        });
        actuator_activity.belongsTo(models.device, {
          foreignKey: 'sensor_device_id',
          onDelete: 'CASCADE',
        });
      };

运行此查询

device.findAll({include:[{model: sensor_data, as: 'sensor_data'}, {model: actuator_activity, as: 'actuator_activities'}]})

返回以下内容：

{
            "id": 2,
            "name": "TEST DEVICE 2",
            "role": "SENSOR",
            "type": "SOIL MOISTURE",
            "io_pin": 5,
            "added_timestamp": "2019-05-01T12:18:08.317Z",
            "client_added_timestamp": "2019-04-23T20:44:29.597Z",
            "min_value": 0,
            "max_value": 1000,
            "sensor_data": [
                {
                    "id": 2,
                    "sensor_device_id": 2,
                    "created_timestamp": "2019-04-23T20:44:29.597Z",
                    "sensor_value": 300
                }
            ],
            "actuator_activities": [
                {
                    "id": 1,
                    "created_timestamp": "2019-04-23T20:44:29.597Z",
                    "name": "Motor turned on",
                    "actuator_device_id": 1,
                    "sensor_device_id": 2
                }
            ]
        },
        {
            "id": 1,
            "name": "TEST DEVICE 1",
            "role": "ACTUATOR",
            "type": "MOTOR",
            "io_pin": 7,
            "added_timestamp": "2019-05-01T12:17:14.026Z",
            "client_added_timestamp": "2019-04-23T20:44:29.597Z",
            "min_value": 0,
            "max_value": 1,
            "sensor_data": [],
            "actuator_activities": []
        }

但我想得到的是：

{
            "id": 2,
            "name": "TEST DEVICE 2",
            "role": "SENSOR",
            "type": "SOIL MOISTURE",
            "io_pin": 5,
            "added_timestamp": "2019-05-01T12:18:08.317Z",
            "client_added_timestamp": "2019-04-23T20:44:29.597Z",
            "min_value": 0,
            "max_value": 1000,
            "sensor_data": [
                {
                    "id": 2,
                    "sensor_device_id": 2,
                    "created_timestamp": "2019-04-23T20:44:29.597Z",
                    "sensor_value": 300
                }
            ],

        },
        {
            "id": 1,
            "name": "TEST DEVICE 1",
            "role": "ACTUATOR",
            "type": "MOTOR",
            "io_pin": 7,
            "added_timestamp": "2019-05-01T12:17:14.026Z",
            "client_added_timestamp": "2019-04-23T20:44:29.597Z",
            "min_value": 0,
            "max_value": 1,
            "actuator_activities": [
                {
                    "id": 1,
                    "created_timestamp": "2019-04-23T20:44:29.597Z",
                    "name": "Motor turned on",
                    "actuator_device_id": 1,
                    "sensor_device_id": 2
                }
            ]
        }

这里的想法是将

id

与嵌套的

执行器\设备\ id

和

传感器\设备\ id

如果我删除了与

执行器\u活动

和

设备

与外键

传感器\u设备\u id

的关联，它将按照我的预期工作，但我需要保留它，因为我需要两列的

执行器\u活动

的级联选项

例如，有没有一种方法可以指定在查询时忽略/排除此特定外键

如果不是，我如何在这里实现我的目标
