Question

是否可以根据关联模型中关系的值对急切集合进行排序？

匹配

$matches = Match::where('tournament_id', $tournamentId)->with([
    'playingMatch', 'playingMatch.court', 'playingMatch.playingSets', 'player', 'opponent'
])->get();

我有一个匹配列表，我使用$matche->each来隔离不同匹配的不同状态：

隔离匹配状态

$upcomingMatches = collect([]);
$currentMatches = collect([]);
$finishedMatches = collect([]);

// Isolate all upcoming, current, and completed matches
$matches->each(function ($match) use ($upcomingMatches, $currentMatches, $finishedMatches) {

    // Has the match been started?
    if (!is_null($match->playingMatch)) {

        // Is the match finished?
        if ($match->playingMatch->finished) {
            $finishedMatches->push($match);
        }
        else {
            $currentMatches->push($match);
        }
    }
    else {
        $upcomingMatches->push($match);
    }
});

示例JSON

array:3 [▼
  0 => array:9 [▼
    "id" => 1
    "tournament_id" => 2
    "player_id" => 1
    "opponent_id" => 2
    "title" => "Quarter Finals"
    "scheduled_start" => "Nov 6, 2015 7:14 pm"
    "playing_match" => array:10 [▼
      "id" => 1
      "match_id" => 1
      "court_id" => 1
      "score_player" => 2
      "score_opponent" => 0
      "start_time" => "2015-11-06 11:14:36"
      "finish_time" => "2015-11-06 11:14:57" <-- sort argument
      "finished" => true
      "court" => array:5 [▶]
      "playing_sets" => array:2 [▶]
    ]
    "player" => array:5 [▶]
    "opponent" => array:5 [▶]
  ]
  1 => array:9 [▶]
  2 => array:9 [▶]
]

但是现在我已经拥有$finishedMatches所有finish_time我想要的$finishedMatches[0]->playingMatch->finish_time，@api.multi @api.depends('name') # seems to depend on record.name ?? def _compute_fats(self): for record in self: fats = 0 fats_id = record.name.id # Are you sure this is correct?? get_detail = self.env['trackfood.foods'].browse([fats_id]) # Faster search by id for record2 in get_detail: fats = record2.fats record.fats = fats位于{{1}}。我似乎无法通过Laravel系列找到一种方法。有什么想法吗？

我相信这会解决问题：

$finishedMatches->sortBy(function($match){
    return $match->playingMatch->finish_time;
});

我也可能会使用过滤器而不是每个过滤器来创建集合。

$finishedMatches = $matches->filter(function ($match) {
    return ($match->playingMatch && $match->playingMatch->finished);
});

$currentMatches = $matches->filter(function ($match) {
    return !($match->playingMatch && $match->playingMatch->finished);
});

$upcomingMatches = $matches->filter(function ($match) {
    return !($match->playingMatch);
});

我的眼睛有点容易：）
