Javascript Sequelize.js joinTableAttributes不工作

我有由sequelize关联自动生成的用户、通知和NotificationsUsers表。我可以向用户获取所有通知，但我希望在关联表中存储“读取”字段TRUE或FALSE值。到目前为止，这一切都已设置，但我无法从关联表中提取“读取”字段

我的代码-

Usr.getNotifications({where: ['Notifications.createdAt >= ?', datetime], joinTableAttributes: ['read']}).success(function(notes) {
    defer.resolve(notes);
});

哪个运行此查询-

SELECT `Notifications`.*, `NotificationsUsers`.`read` as `NotificationsUser.read` FROM `Notifications`, `NotificationsUsers` WHERE `NotificationsUsers`.`UserId` = 1 AND `NotificationsUsers`.`NotificationId` = `Notifications`.`id` AND Notifications.createdAt >= '0000-00-00 00:00:00';

我得到的只是通知表字段。我得到的一个结果的例子-

{ dataValues: 
 { id: 7,
   type: 'Warranty',
   title: 'Warranty Request From Jim Bob',
   text: 'My sink is drippy. I don\'t like drippy sinks.' },
_previousDataValues: 
 { id: undefined,
   type: undefined,
   title: undefined,
   text: undefined },
__options: 
 { timestamps: true,
   createdAt: 'createdAt',
   updatedAt: 'updatedAt',
   deletedAt: 'deletedAt',
   instanceMethods: {},
   classMethods: {},
   validate: {},
   freezeTableName: false,
   underscored: false,
   syncOnAssociation: true,
   paranoid: false,
   whereCollection: [Object],
   schema: null,
   schemaDelimiter: '',
   language: 'en',
   defaultScope: null,
   scopes: null,
   hooks: [Object],
   omitNull: false,
   uniqueKeys: {},
   hasPrimaryKeys: false },
options: { isNewRecord: false, isDirty: false },
hasPrimaryKeys: false,
selectedValues: 
 { id: 7,
   type: 'Warranty',
   title: 'Warranty Request From Jim Bob',
   text: 'My sink is drippy. I don\'t like drippy sinks.',
   createdAt: Fri Sep 05 2014 11:18:40 GMT-0500 (CDT),
   updatedAt: Fri Sep 05 2014 11:18:40 GMT-0500 (CDT) },
__eagerlyLoadedAssociations: [],
isNewRecord: false,
NotificationsUser: 
 { dataValues: [Object],
   _previousDataValues: [Object],
   __options: [Object],
   options: [Object],
   hasPrimaryKeys: true,
   selectedValues: [Object],
   __eagerlyLoadedAssociations: [],
   isNewRecord: false } }

根据这些信息，有什么建议我可能做错了什么？为什么我不能获取NotificationsUsers.read字段？

读取字段应该在notes.NotificationUser.read中。谢谢！我以前没有注意到这一点。另一方面：where记录了您必须将原始查询传递给生成的get方法而不是对象的where？
