如何使用Ember中的路由对模型进行排序？ [英] How to sort model using only a route in ember?

问题描述

过去，您可以使用ArrayController（在1.13.0中不推荐使用），并且我们知道在ember中不推荐使用短控制器。目前可以使用我的路线对我的模型进行排序吗？

In the past you could use ArrayControllers (deprecated in 1.13.0), and we know that shortly controllers won't be recommended in ember. Is it currently possible to sort my model using only my route?

ie

/routes/orders.js

import Ember from 'ember';

export default Ember.Route.extend({
  model: function() { return this.store.findAll('order'); }
});

我以名称为例排序，但只使用路由？

How would I sort by 'name' as an example, but only using a route?

请注意，此问题类似于如何在Ember.js中排序模型？ - 但是它是通过任何方法，而我的问题是特定于只使用路由（如果可能的话）。

Note that this question is similar to How to sort model in Ember.js? - but there it is via any method, whereas my question is specific to doing it only using a route (if possible).

推荐答案

新的答案帖子Ember 2.0

虽然问题仍然存在，torazaburo的答案在Ember 2.0之前工作得很好。现在最好的答案是不要仅使用路由对模型进行排序 - 而是在控制器中执行排序，或者不想在组件中使用控制器。

Although the question still stands and torazaburo's answer works great before Ember 2.0. The best answer now is "don't sort a model using only a route" - instead do the sorting in a controller, or if you don't want to use a controller then in a component.

Ember 2.0后面的重新加载行为有一个很大的'getcha'。如果存储中已经存在记录，并且在findAll选项中没有指定{reload：true}，那么findAll方法将立即用这些记录来解析，这意味着只有这些记录才能被存储。因此，您的模型可能会返回有限数量的记录，而实际的后台请求仍在继续。请参阅DS Store文档以获取更多信息。

There is a big 'gotcha' with the reload behaviour post Ember 2.0. If there are already records in the store, and you do not specify { reload: true } in the options of findAll, then the findAll method will instantly resolve with those records, meaning the then only sorts with those records you already had. So your model could return with a limited number of records while the actual background request is still going on. See DS Store docs for further info.

因此，基于以前接受的答案的改进代码为：

The improved code based on the previously accepted answer is therefore:

export default Ember.Route.extend({
  model: function() { 
    return this.store.findAll('order', { reload: true }).
      then(orders => orders.sortBy('name'));
    }
});

但是如前所述，我认为最好的做法是不要仅仅依靠路线，而是使用控制器或组件中的计算排序。

But as previously mentioned, I think the best course of action is to not rely solely on the route, but instead use computed sort in either a controller or a component.
