如何在json渲染中获取完整的belongs_to对象? [英] How to get full belongs_to object in json render?

问题描述

基本上，我有一个对象belongs_to :companies，并且有:company_id 属性.当我呈现 json: @coupons 时，JSON 是否可能包含其所有者的属性而不是 company_id?

Basically, I have an object that belongs_to :companies, and has the :company_id attribute. When I render json: @coupons, is it possible for the JSON to contain an attribute of its owner rather than the company_id?

推荐答案

你也许可以做一些类似 render :json =>@coupons.to_json(:include => :company)，至少它似乎与我在 rails 2.3.8 中的初始测试一起工作.

You might be able to do something like render :json => @coupons.to_json(:include => :company), at least it seems to have worked with my initial testing in rails 2.3.8.

已编辑答案以使用 :include =>:company 而不是 :include =>:公司
