我正在尝试像这样更新 Laravel Eloquent 模型。
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 . "')")
]);
});
});
但它不起作用。
换句话说,我想更新如下。
-
如果“reason”为 null 或空字符串
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
]);
-
else
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 . "')")
]);
我的错误是什么?我怎样才能使陈述更简单?请告诉我~
使用方法是错误的update
回调函数内部where
功能
您必须通过两个查询来完成此操作,例如:
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 . '")'),
]);
