Question

我正在使用Laravel 5.2，并且我的部分响应太慢，我发现在foreach循环中发生了大延迟，每行花费一秒钟，我列出了大约100个寄存器，这使得该站点非常慢。很少见，因为我只显示7列，并且该表总共213行，而该表只有16列。

我该怎么办？这是foreach块。仅在生产环境中运行就需要这么长时间

@foreach($tickets as $ticket)
          <tr>
            <td>
              {{ $ticket->id }}
            </td>
            <td>
              {{ $ticket->creator->worksAt->nombre }}
            </td>
            <td>
              {{ $ticket->patient->toArray()['rut'] }}
            </td>
            <td>
              {{ $ticket->getProcessName() }}
            </td>
            <td>
              {{ $ticket->created_at->format('d M Y') }}
            </td>
            @if ($ticket->getProcessSla() == $ticket->getLatency() )
              <td  class="alert-warning">
            @elseif ($ticket->getProcessSla() < $ticket->getLatency() )
              <td  class="alert-danger">
            @else
              <td  class="alert-success">
            @endif
              {{ $ticket->getLatency() }} días
              (Límite: {{ $ticket->getProcessSla() }})
            </td>
            <td>
              @if ( null !== Auth::user()->roles->find($ticket->getProfileId()) )
                {{ Form::open(array('action'=>'StageController@redirect')) }}
                  {{ Form::hidden('ticket_id', $ticket->cryptId()) }}
                  {{ Form::hidden('process_id', $ticket->cryptProcessId()) }}
                  {{ Form::submit('Iniciar', ['class'=>'btn btn-xs btn-block btn-primary']) }}
                {{ Form::close() }}
              @endif
            </td>
          </tr>
    @endforeach

Answer 1

让我们在这里计算查询和其他操作的次数：

$ticket->creator：查询
creator->worksAt可能是另一个查询（猜测为未提供源代码）
$ticket->patient：查询
$ticket->getProcessName()：查询
$ticket->getProcessSla()：查询
Auth::user()->roles：查询
$ticket->cryptId()：加密
$ticket->cryptProcessId()：加密+查询（用于查找过程）

总共：7个查询+每个票证2个加密乘以213行。

相当于 1,491个查询和426种加密。难怪它很慢？不是foreach。

您需要通过eager loading，pagination，持久性存储（用于加密）和备注（而不是在数据库中多次重复查找相同的流程模型）进行优化。

Laravel 5.2中使用Blade的foreach太慢
