如何使用链接重新加载异步有许多关系? [英] How to reload an async with links hasMany relationship?

问题描述

假设我们有

Post = DS.Model.extend({
  comments: DS.hasMany({async: true})
})

Comment = DS.Model.extend({
  post: DS.belongsTo()
})

而且我必须使用 links 功能，否则我会因帖子评论过多而收到 414 错误.

and I have to use the links feature because otherwise I get a 414 error due to too much comments on a post.

自从这次提交https://github.com/emberjs/data/commit/4d717bff53f8c93bedbe74e7965a4f439882e259"/a>

Since this commit https://github.com/emberjs/data/commit/4d717bff53f8c93bedbe74e7965a4f439882e259

似乎不可能触发 post.get('comments') 的重新加载，即在例如 post/42/comments 上发送 GET 请求.

It seems like it's impossible to trigger a reload of the post.get('comments'), ie sending a GET request on for example post/42/comments.

有什么解决办法吗?

推荐答案

感谢@igorT，这已经实现了.https://github.com/emberjs/data/pull/2297

Thanks to @igorT, this is implemented. https://github.com/emberjs/data/pull/2297

现在 ManyArray 有一个 reload() 方法，如果关系尚未加载，您甚至可以调用该方法.

Now the ManyArray has a reload() method, which you can even call if the relation has not been loaded yet.

您可以通过阅读测试
