Laravel雄辯的模型更新根據字段值null或現有的條件

Question

我想更新Laravel雄辯模型是這樣的。

Res_Reservations::where('time_id', $time['id']) 
       ->where('date', $bus['date']) 
       ->where('valid', config('config.TYPE_SCHEDULE_UNREMOVED')) 
       ->where(function($query) use($time, $notesAdd) { 
        $query->whereNull('reason', function($query) use ($time, $notesAdd) { 
         return $query->update([ 
          'time_id' => $time['move'], 
          'reason' => $notesAdd 
         ]); 
        }) 
        ->orWhere('reason', '=', '', function($query) use ($time, $notesAdd) { 
         return $query->update([ 
          'time_id' => $time['move'], 
          'reason' => $notesAdd 
         ]); 
        }) 
        ->orWhere('reason', '<>', '', function($query) use ($time, $notesAdd) { 
         return $query->update([ 
          'time_id' => $time['move'], 
          'reason' => DB::raw("CONCAT(reason, \r\n'" . $notesAdd . "')") 
         ]); 
        }); 
       }); 

但它不工作。

換句話說，我想更新如下。

• 如果 '理由' 爲空或emptystring

  Res_Reservations::where('time_id', $time['id']) 
         ->where('date', $bus['date']) 
         ->where('valid', config('config.TYPE_SCHEDULE_UNREMOVED')) 
         ->update([ 
          'time_id' => $time['move'], 
          'reason' => $notesAdd 
         ]); 
  

• 其他

  Res_Reservations::where('time_id', $time['id']) 
         ->where('date', $bus['date']) 
         ->where('valid', config('config.TYPE_SCHEDULE_UNREMOVED')) 
         ->update([ 
          'time_id' => $time['move'], 
          'reason' => DB::raw("CONCAT(reason, '\r\n" . $notesAdd . "')") 
         ]); 
  

  什麼是我的錯？我怎樣才能簡化陳述？請讓我知道〜

這是錯誤的使用where功能的回調內部update功能

你必須這樣做，在2個查詢：

Res_Reservations::where('time_id', $time['id']) 
    ->where('date', $bus['date']) 
    ->where('valid', config('config.TYPE_SCHEDULE_UNREMOVED')) 
    ->where(function ($query 
    { 
     $query->where('reason', null) 
      ->orWhere('reason', ''); 
    }) 
    ->update([ 
     'time_id' => $time['move'], 
     'reason' => $notesAdd, 
    ]); 


Res_Reservations::where('time_id', $time['id']) 
    ->where('date', $bus['date']) 
    ->where('valid', config('config.TYPE_SCHEDULE_UNREMOVED')) 
    ->where('reason', '!=', null) 
    ->where('reason', '!=' ''); 
    ->update([ 
     'time_id' => $time['move'], 
     'reason' => DB::raw('CONCAT(reason, "\r\n' . $notesAdd . '")'), 
    ]);
