Laravel集合sortBy没有生效

Question

我正在尝试将来自多个数据库查询的结果进行组合和排序.

$events = collect();

$downedEvents = EventDowned::where('mission', $missionId)
   ->orderBy('mission_time', 'asc')
   ->get();

$events->push($downedEvents);

$getInOutEvents = EventGetInOut::where('mission', $missionId)
   ->orderBy('mission_time', 'asc')
   ->get();

$events->push($getInOutEvents);

$missileEvents = EventMissile::where('mission', $missionId)
   ->orderBy('mission_time', 'asc')
   ->get();

$events->push($missileEvents);

$flattenedEvents = $events->flatten();
$sortedEvents = $flattenedEvents->sortBy('mission_time');

return $sortedEvents->all();

结果如下:

正如您所看到的,它已正确组合结果,但它们仍保留在原始查询顺序中,而不是已排序.

我也试过了

$sortedEvents = $flattenedEvents->sortBy(function($event) {
    return (int) $event->mission_time;
});

Answer 1

一个巨大的失败,我的漂亮的打印JSON铬扩展正在弄乱显示顺序,查看原始响应显示他们实际上正确排序... :: facepalm ::

Answer 2

为了扩展@Titan的答案，我想扩展名/邮递员将保持数组索引顺序。不太确定。

摆脱那个

return $collection->values();

这是一个例子

$arr = collect([
  0 => [
      'name' => 'foo',
      'weight' => 70
  ],
  1 => [
      'name' => 'bar',
      'weight' => 80
  ]
 ]);

return $arr->sortByDesc('weight');

该扩展名仍将保留索引顺序

return $arr->sortByDesc('weight')->values();

这将获得所需的顺序。
