我想显示各个俱乐部的所有球员，并在 laravel 的表格中有一些问题

Question

我有一个带有字段的俱乐部表：

id,name,est_date,CEO ....

我有球员表有字段：

id, name,DOB,height,weight, .....

player_histories 表：

id,player_id,previous_club_id,current_club_id,position, ......

club_histories 表：

club_id, championship_id,status, ...

在 club_histories 的查看页面中，我可以显示：

club name,championship name and status...

但我也想在 club_histories 表中显示俱乐部的相应球员......这怎么可能？？？ 请回复...

编辑部分：添加代码

Routes.php：

Route::resource('clubhistories','ClubHistoryController');

ClubHistoryController.php：

public function show($id,ClubHistory $clubhistories)
{
    $club=$clubhistories->find($id);

    $clubhistories=$clubhistories->getPlayerByCLub();
    return view('pages.singleClub',compact('club','clubhistories'));
}

ClubHistoryRepository.php

  public function getPlayerByCLub(){
    return $this->makeModel() ->join('clubs', 'clubs.id', '=', 'club_histories.club_id')
        ->join('player_histories','player_histories.current_club_id', '=', 'clubs.id')
        ->join('players', 'players.id', '=', 'player_histories.player_id')
        ->get([
            'clubs.name',
            'player_histories.player_id',
            'players.name',
        ]);
}

SingleClub.blade.php：

 <div class="tab-content">
                    <div class="tab-pane in active" id="basic">

                        <table class="table table-condensed">
                            <thead>
                            <tr>
                                <th>Name</th>
                                <th>contact</th>
                            </tr>
                            </thead>
                            <tbody>
                                <tr>
                                  <td>Name:</td>
                                  <td>{!!$club->club->name!!}</td>

                                </tr>
                                  <tr>
                                      <td>Contact:</td>
                                      <td>{!!$club->club->contact_no!!}</td>
                                   </tr>
                            </tbody>
                        </table>

                            </tr>
                            @endforeach
                            </tbody>
                        </table>
                    </div>

上面使用的加入和您给出的解决方案给出了相同的解决方案..我想将俱乐部对象中的俱乐部历史找到的相同 id 传递给俱乐部历史对象，以便显示俱乐部的所有球员.. 你能帮帮我吗..

Answer 1

您可以通过连接（较少查询）或 Eloquent 关系（看起来更简单的代码）查看 club_histories 中的球员。

使用Eloquent Relationships（假设您已设置它们）：

$histories = ClubHistory::with('players', 'club')->get();

// In your blade view
@foreach ($histories as $history)
    <p>{{ $history->club->name }} won {{ $history->championship_name }}</p>
    <p>Status: {{ $history->status }}
    <div>Player list:
        <ul>
            foreach ($history->players as $player)
                <li>{{ $player->name }}</li>
            @endforeach
        </ul>
    </div>
@endforeach

加入查询生成器：

DB::table('club_histories')
    ->join('player_histories',
        'player_histories.current_club_id', '=', 'club_histories.club_id')
    ->join('players', 'players.id', '=', 'player_histories.player_id')
    ->join('club', 'club.id', '=', 'club_histories.club_id')
    ->get([
        'club.name AS clubName',
        'club_histories.championship_name',
        'club_histories.status',
        'player_histories.player_id',
        'players.name AS playerName',
    ]);

请注意，以上内容将为每个俱乐部历史记录中的每位球员返回一行

编辑：

查看您的代码后，下面是上面的一个版本，它应该适用于您的非标准代码库。请务必将 ID 传递给getPlayerByClub($id)。

ClubHistoryRepository.php

public function getPlayerByCLub($clubHistoryId) {
    return $this->makeModel()
        ->join('clubs', 'clubs.id', '=', 'club_histories.club_id')
        ->join('player_histories', 'player_histories.current_club_id', '=', 'clubs.id')
        ->join('players', 'players.id', '=', 'player_histories.player_id')
        ->where('club_histories.id', '=', $clubHistoryId)
        ->get([
            'clubs.id',
            'club_histories.championship_name',
            'club_histories.status',
            'player_histories.player_id',
            'clubs.name',
            'players.name',
        ]);
}
