计算Laravel中的数据

我想根据Laravel 5.7中的状态对数据进行计数。我有六个状态(“已分配”,“在途中”,“已开始”,“取消工作程序”,“取消管理员”和“关闭”)。我必须在foreach数据中对此进行查询。

这是我的代码:

  $data['list_detail'] = [];

  foreach ($listFa as $value) {
    $type = $value->type;
    $descr = $value->descr;

    $c_ass_detail = transaction::where('type', $value->type)
                                ->where('status','like','%Assigned%')
                                ->groupBy('type')
                                ->count();

    $c_otw_detail = transaction::where('type', $value->type)
                                ->where('assign_status','like','%On The Way%')
                                ->groupBy('type')
                                ->count();

    $c_str_detail = transaction::where('type', $value->type)
                                ->where('assign_status','like','%Started%')
                                ->groupBy('type')
                                ->count();

    $c_cbw_detail = transaction::where('type', $value->type)
                                ->where('assign_status','like','%Cancel Worker%')
                                ->groupBy('type')
                                ->count();

    $c_cba_detail = transaction::where('type', $value->type)
                                ->where('assign_status','like','%Cancel Admin%')
                                ->groupBy('type')
                                ->count();

    $c_cls_detail = transaction::where('type', $value->type)
                                ->where('assign_status','like','%Closed%')
                                ->groupBy('type')
                                ->count();

    $total = $c_ass_detail +  $c_otw_detail +  $c_str_detail +  $c_cbw_detail + $c_cba_detail + $c_cls_detail;                         

    array_push($data['list_detail'], array('type'=>$type, 'descr'=>$descr, 'c_ass_detail'=>$c_ass_detail, 'c_otw_detail'=>$c_otw_detail, 'c_str_detail'=>$c_str_detail, 'c_cbw_detail'=>$c_cbw_detail, 'c_cba_detail'=>$c_cba_detail, 'c_cls_detail'=>$c_cls_detail, 'total'=>$total));
  }

这是我的查看代码:

   <tbody>
       @foreach($list_detail_fa as $row)
      <tr class="tr_dashboard">
          <td>{{ $row['fa_type_cd'] }}</td>
          <td>{{ $row['descr'] }}</td>
          <td>{{ $row['c_ass_detail'] }}</td>
          <td>{{ $row['c_otw_detail'] }}</td>
          <td>{{ $row['c_str_detail'] }}</td>
          <td>{{ $row['c_cbw_detail'] }}</td>
          <td>{{ $row['c_cba_detail'] }}</td>
          <td>{{ $row['c_cls_detail'] }}</td>
          <td>{{ $row['total'] }}</td>
      </tr>
       @endforeach                    
   </tbody>

它正在工作,但是我认为这种方式不好,因为刷新页面时,显示数据太慢了。也许是因为有许多相同的查询。因此,如果我只想对每种状态使用一个查询来对数据进行计数,该怎么办?

您需要在查询中将聚合函数count与分组依据一起使用。假设您的表名是事务。试试吧!

$typeCounts = DB::table('transactions')
              ->select('type', 'assign_status', DB::raw('count(type) as type_count'))
              ->where('type', $value->type)
              ->groupBy('assign_status')
              ->get();

然后在树枝中,您可以像这样访问它:

   <tbody>
      <tr class="tr_dashboard">
         @foreach($typeCounts as $row)
          <td>{{ $row['type_count'] }}</td>
        @endforeach    
      </tr>                  
   </tbody>

您为自己过度繁琐:

您只需要:

$allTypes = array_map(function ($value) {
           return $value->type;
}, $listFa);

 $c_ass_detail = transaction::whereIn('type', $allTypes)
                            ->groupBy('type')
                            ->groupBy('assign_status')
                            ->select('type', 'assign_status', \DB::raw('count(*) as count'))
                            ->get();

然后您的$c_ass_detail将为每种类型排一行,分配状态,计数组合。
