php – Laravel ::结合两个DB查询对象

前端之家收集整理的这篇文章主要介绍了php – Laravel ::结合两个DB查询对象前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我在我的游戏模型中有一个方法,它检索在一个数据库中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,最后从数据库中抓取一个随机图像URL并将其附加到统计对象.困惑了吗?

不要再困惑了,这是方法

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所以它在一个地方,目前该方法失败,原因是:不能使用stdClass类型的对象作为数组

没有地图,当循环$stats时,它是一个游戏统计数组,其中键作为游戏名称.

如果你仍然感到困惑(我不会责怪你),那么请留言,我会解释更多.

编辑:

这是我尝试使用 – > merge():

public static function getStats($player,return the statistics from the games database for that game


        // Grab game Meta information from the website database

        $list = Game::where('game',$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;
}

这导致调用运行Laravel 4.2的未定义方法stdClass :: merge().

合并()

merge方法将给定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

方法的唯一参数是应合并的集合.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);
