Laravel :: 组合两个数据库查询对象

Question

我的 Game 模型中有一个方法，它检索在一个数据库的表中注册的所有游戏的列表，遍历找到的每个游戏并从另一个数据库获取数据，最后抓取一个随机来自数据库的图像 URL 并将其附加到统计对象。困惑了吗？

别再纠结了，方法如下：

public static function getStats($player, $cache = 30) {

    // Return a collection of all games registered from the website database

    $games = Game::get(['game']);

    foreach($games as $game) {

        // For each iteration, return the statistics from the games database for that game


        // Grab game meta information from the website database, $game->game is the game name.

        $list = Game::where('game', $game->game)->remember($cache)->first();


        // From the game database, retrieve the statistics 

        $stats[$game->game] = DB::connection('game')->table($list->stats_table)
                                                    ->select(DB::raw($list->statistics))
                                                    ->where('Username', $player)
                                                    ->remember($cache)
                                                    ->first();

        // Grab a random map image from the game database

        $stats[$game->game]['map'] = DB::connection('game')->table('Maps')
                                                           ->select('Image')
                                                           ->orderBy(DB::raw('RAND()'))
                                                           ->remember($cache)
                                                           ->first();


    }

    // Finally, return the statistics from the game paired with a random map image from the game

    return $stats;

}

我想将地图查询附加到 $stats 上，以便将其全部放在一个地方，目前该方法因以下原因而失败：无法将 stdClass 类型的对象用作数组

没有地图，在 $stats 上循环时，它是一个游戏统计数据数组，键为游戏名称。

如果您仍然感到困惑（我不会怪您），请发表评论，我会解释更多。

编辑：

这是我使用->merge()的尝试：

public static function getStats($player, $cache = 30) {

    // Return a collection of all games registered from the website database

    $games = Game::get(['game']);

    foreach($games as $game) {

        // For each iteration, return the statistics from the games database for that game


        // Grab game meta information from the website database

        $list = Game::where('game', $game->game)->remember($cache)->first();


        // From the game database, retrieve the statistics 

        $stats[$game->game] = DB::connection('game')->table($list->stats_table)
                                                    ->select(DB::raw($list->statistics))
                                                    ->where('Username', $player)
                                                    ->remember($cache)
                                                    ->first();

        // Grab a random map image from the game database

        $map = DB::connection('game')->table('Maps')
                                   ->select('Image')
                                   ->orderBy(DB::raw('RAND()'))
                                   ->remember($cache)
                                   ->first();

        $stats[$game->game] = $stats[$game->game]->merge($map);



    }

    // Finally, return the statistics from the game paired with a random map image from the game

    return $stats;
}

这会导致 调用未定义的方法 stdClass::merge() 运行 Laravel 4.2。

Answer 1

merge()

merge 方法将给定的数组合并到原始集合中。如果给定数组中的字符串键与原始集合中的字符串键匹配，则给定数组的值将覆盖原始集合中的值

该方法的唯一参数是应该合并的集合。这是一个例子。

<?php

// app/routes.php

Route::get('/', function()
{
    $a = Album::where('artist','Something Corporate')
        ->get();
    $b = Album::where('artist','Matt Nathanson')
        ->get();

    $result = $a->merge($b);

    $result->each(function($album)
    {
        echo $album->title.'<br />';
    });
});

其他

$array = array_merge($stats[$game->game]->toArray(), $map->toArray()); 
return Response::json($array);
