hasMany关系:包括从另一个方向

本文介绍了hasMany关系:包括从另一个方向的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

说我有下一个模型:

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

又名用户可能有很多发票.这段代码将字段ReceiverId添加到发票模型中.

A.k.a. a user might have many invoices. This code adds the field receiverId to the invoice model.

现在，我想获取一张发票清单，包括其收货人.我该怎么办?

Now I want to get a list of invoices including their receivers. How can I do that?

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

或

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

不起作用，返回:未为发票模型定义关系\"接收器\"错误.

Did not work, returned: "Relation \"receiver\" is not defined for Invoice model" error.

感谢您的帮助.

推荐答案

您必须定义在您的帐单模型中属于属于" 关系.

invoice.json:

invoice.json:

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

然后您可以像这样查询模型:

Then you can query your model like this:

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