Question

我有两张桌子 1.

Game Console
      -- console_id
      -- console_name

2

 Game Labels
     -- game_label_id
     -- console_id (foreign key)
     -- title
     -- description 
     -- image
     -- created

GameConsole模型

namespace App\Http\Models;

use Illuminate\Database\Eloquent\Model;

class GameConsole extends Model
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    public $timestamps = false;
    protected $table = 'console';
    protected $fillable = array('console_name', 'description', 'created');
    protected $primaryKey = 'console_id';

    public function labels()
    {
        return $this->hasMany('App\Http\Models\GameLabel','console_id');
    }

}

GameLabel模型

namespace App\Http\Models;

use Illuminate\Database\Eloquent\Model;

class GameLabel extends Model
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    public $timestamps = false;
    protected $table = 'game_label';
    protected $fillable = array('game_label_id','console_id', 'title','description','image', 'release_date','status','created');
    protected $primaryKey = 'game_label_id';

    public function console()
    {
        return $this->belongsTo('App\Http\Models\GameConsole','console_id');
    }
}

我编写此查询以获取所有带有console_name的游戏标签

GameLabel::with('console')->get();

但我只是从game_label表中获取记录，而不是从控制台表中获取记录。

任何人都可以告诉我，为了获得所有记录，我必须写什么查询？请不要向我推荐有关查询构建器连接的信息。我不想用它。

Answer 1

       namespace App\Http\Models;

        use Illuminate\Database\Eloquent\Model;

        class GameLabel extends Model
        {
            /**
             * The attributes that are mass assignable.
             *
             * @var array
             */
            public $timestamps = false;
            protected $table = 'game_label';
            protected $fillable = array('game_label_id','console_id', 'title','description','image', 'release_date','status','created');
            protected $primaryKey = 'game_label_id';

            public function console()
            {
               return $this->belongsTo('App\Http\Models\GameConsole', 'console_id', 'console_id');
           }
}

in属于第一个console_id代表Game Console表id，第二个console_id代表game_label table console_id

现在在控制器

GameLabel::with('console')->get();

我认为所有数据都将在控制台密钥下的数组中显示

Answer 2

是的，它在控制台键下。我找到了解决方案。控制台名称未进入视图，因此请在视图中获取控制台名称

foreach($game_label as $getGameLabel){
    echo $getGameLabel->console->console_name;
}
