Question

说我有下一个型号：

user.json:
{//...
    "relations":{
        "invoices": {
            "type": "hasMany",
            "model": "Invoice",
            "foreignKey": "receiverId"
        },
    }
//...
}

A.k.a。用户可能有很多发票。此代码将字段receiverId添加到发票模型中。

现在我想获得一张包括收件人在内的发票清单。我怎么能这样做？

Invoice.find({include: "reciever"})

或者

Invoice.find({include: "user"})

无法正常工作，返回：“没有为发票模型定义”关系\“接收器\”错误。

感谢您的帮助。

Answer 1

You have to define belongsTo relation in your Invoice model.

invoice.json:

{//...
    "relations":{
        "receiver": {
            "type": "belongsTo",
            "model": "Receiver"
        },
    }
//...
}

Then you can query your model like this:

Invoice.find({include: "receiver"}, function(data){ 
   console.log(data);
});

hasMany关系：包括从另一个方向
