Laravel 4.2 Eloquent 检查 ID

Question

我有两张桌子

"hostgame" -> 托管游戏的地方 “游戏”-> 托管的每个游戏都在这里获取各自的所有信息

我们将在“hostgame”表中获得“game_id”，截至目前，所有游戏都发布在网站上，我想在“hostgame”表中根据“game_id”过滤这些游戏，并且仅显示已托管的游戏。

我该怎么做？

GameController.php

    public function select()
{
    // TODO: Pls revise this. This is not the right way to do
    $weekly_dates = $this->get_days( Config::get('game.year'), 9  );

    $this->params['weekly_dates'] = $weekly_dates;
    $this->params['weekly_games'] = array();

    foreach($weekly_dates as $date ) {

        $from = date('Y-m-d 00:00:00', strtotime($date));
        $to = date('Y-m-d 23:59:59', strtotime($date));

        //foreach($hostgames as $hostgame){
        $this->params['hostgame'] = Hostgame::all();
        dd($this->params['hostgame']);
        $this->params['weekly_games'][$date] = Game::whereRaw('schedule >= ? and schedule <= ?', array($from, $to) )->get();
        //}

        //$this->params['weekly_games'][$date] = Game::has()('schedule >= ? and schedule <= ?', array($from, $to) )->hostgames();
        //$this->params['weekly_games'][$date] = Hostgame::whereHas('game', function($q) {
            //$q->whereRaw('schedule >= ? and schedule <= ?', array('34365', '2435') )->get();
        //});

    }

select.blade.php

          <?php $day = 0 ?>
      @foreach ($weekly_games as $date => $games )
      @if($games)
      <div id="slide-content-{{ $day }}">
        <h2>Sunday Games {{ $date }}</h2>
          @foreach ($games as $game )

          <p><a href="{{ URL::to('game/draft/'.$game->id) }}"> {{ $game->home_name }} Vs {{ $game->away_name }}</a></p>
          @endforeach
        @endif
      </div>
      <?php $day++ ?>
      @endforeach

谢谢，现在所有游戏都按各自的日期显示。 我只想显示已托管的游戏。

有多种方法可以实现您的目标。由于您的主机列表中已经有您的游戏 ID，请尝试以下操作：

1. 将单个游戏的功能添加到 GameController.php public function getSingleGame($id) { // logic here }
2. 接下来，将以下（控制器）路由添加到您的 routes.php 以在路由、控制器和模板之间建立链接：Route::get('game/draft/{id}', ['as' => 'show_single_game', 'uses' => 'GameController@getSingleGame']); 您现在可以通过特定名称访问路由（show_single_game）。
3. 现在你可以像这样编写你的 URL 路由：{{ link_to_route('show_single_game', $game->home_name . " Vs " . $game->away_name, array($game->id) ) }} Laravel 会为你创建链接，所以不用担心 URL，它现在由路由设置。

GameController getSingleGame 的逻辑：

public function getSingleGame($id) {
    // find the game by id
    $game = Game::findOrFail($id); 

    // assuming your template is located in views/games/show.blade.php
    return View::make('games/show')
        ->with('game', $game);
}
