ember-data：如何判断模型的异步：真实关系是否加载而不触发负载？ [英] ember-data: How to tell if a model's async: true relationship is loaded without triggering a load?

问题描述

我需要检查一个异步关系是否已加载而不触发负载，这是可能的吗？

I need to check if an async relationship has been loaded without triggering the load, is this possible?

推荐答案

没有正式的方法来完成这个，但是非官方地你可以做

There is no official way to accomplish this yet, but unofficially you can do

// this will be null if not loaded, and populated if it has at least started loading
if(model._relationships.yourRelationshipName) {...}
