【问题描述】：

我需要添加我的刀片视图中显示的两个数字/金额，如下图所示

我需要显示为 666.68 / 1000 AUD

这是我的blade 代码

    <td>
          @foreach ($team->competitionPayments as $payment)
                {{ $payment->amount }}
          @endforeach

          <br>

         {{ $team->competitionPayments }}
         /
         @foreach ($team->competitions as $total)
          {{ $total->pivot->total_fee .' AUD'}}
         @endforeach
   </td>

这是我的controller 函数

public function detailedRegistrations($competition)
{

    $competitions = $this->competitionsRepo->findOrFail($competition);

    $teams = $competitions->teams()->get();

    $payments = $competitions->payments()->get();

    return view('competitions.detailed-registrations',
                    [
                        'teams'=>$teams,
                        'payments'=>$payments,
                        'competitions'=>$competitions,
                    ]
                );
}

这是Team model 中的competitionPayments 关系

public function competitionPayments()
{
    return $this->hasMany(CompetitionPayment::class, 'team_id');
}

请告诉我如何完成这项工作

【问题讨论】：

$team->competitions->sum('total_fee') ?
@Kamlesh Paul 不，我需要得到总金额
然后试试$team->competitionPayments->sum('amount')
@KamleshPaul 成功！成功了，谢谢！

【解决方案1】：

这里的competitionPayments 是一个集合，所以你可以在它上面应用sum() 函数

<td>
  {{ $payment->competitionPayments->sum('amount') }}
<br>

【解决方案2】：

这行得通

<td>
    {{ $team->competitionPayments->sum('amount') }}
    /
    @foreach ($team->competitions as $total)
    {{ $total->pivot->total_fee .' AUD'}}
    @endforeach
</td>
