Question

这是我的模型对象和get方法。

模型对象：models.js

var Client = sequelize.define("Client", {
    name: DataTypes.STRING(100),
    status : DataTypes.STRING(1)
});

var Lob = sequelize.define("Lob", {
    name : DataTypes.STRING(100),
    status : DataTypes.STRING(1)
});

Lob.belongsTo(Client, { constraints: true, foreignKeyConstraint:true  });

获取方法：

router.get('/getlobs', function(req, res) {
    models.Lob.find({ where: { "id": 2000 }, include: [models.Client], attributes:["id", "name", "status"]}).then(function(lobs) {
        return res.send(lobs);
    });
});

使用out包含它可以正常获取所需的属性，而我正在尝试获取包含客户端模型的错误。实际上我打算使用外键关系获取ClientId的客户端名称。

查询：

Executing (default):
SELECT `Lob`.`id`, `Lob`.`name`, `Lob`.`status`, `Client`.`id`
  AS `Client.id`, `Client`.`Client_Name`
  AS `Client.Client_Name`, `Client`.`Address`
  AS `Client.Address`, `Client`.`Status`
  AS `Client.Status`, `Client`.`Created_By`
  AS `Client.Created_By`, `Client`.`createdAt`
  AS `Client.createdAt`, `Client`.`updatedAt`
  AS `Client.updatedAt` FROM `Lobs`
  AS `Lob` LEFT OUTER JOIN `Clients`
  AS `Client` ON `Lob`.`ClientId` = `Client`.`id` WHERE `Lob`.`id` = 2000;

错误：

无法包含模型来检索值
