Angular 如果 ng-repeat multi filter 为空

Question

假设我的 ng-repeat 中有多个过滤器，如下所示：

input.search(ng-model="filter", placeholder="Search...")

ul.list
  li(ng-if="things.length === 0") It looks like we don't have any things.
  li(ng-repeat="thing in things | orderBy:'name' | filter: search")
    span {{ thing.name }}

现在，如果我最初没有 things，那么我会收到这样的消息。但是，如果我过滤了没有结果的东西，它就不会显示消息，我明白这一点。

我的问题是，如何实现多重筛选器 ng-repeat 并在收集或筛选器未产生结果时显示消息？

我弄乱了 this example 无济于事。我的尝试：

thing in filteredThings = thing | orderBy: 'name' | filter: search

你很接近，语法有点不对：

(ng-repeat="thing in filteredThings = (things | orderBy:'name' | filter: search"))

li(ng-if="filteredThings.length === 0") It looks like we don't have any things.
