在Laravel中更新多行数据库

Question

我想要一个代码来更新多行数据库,如下所示:

UPDATE values SET data='{"options":["male","female"],"default":"male"}' where project_id=1 and id=1;
UPDATE values SET data='{"options":["male","female"],"default":"male"}' where project_id=1 and id=2;
UPDATE values SET data='{"options":["male","female"],"default":"male"}' where project_id=1 and id=3;

几个小时后,我可以在laravel框架中得到类似的结果:

$values = Value::where('project_id', $id)->get();
$sql = "";
foreach($request->fields as $field) {
  if(!empty($field->default)) { //New default value is set
    foreach($values as $value) {
      $data = json_decode($value->data, true); /**data column as json object in mysql database **/
      $data["default"] = $field->default;
      $data = json_encode($data);
      $sql .= "update ".DB::connection()->getDatabaseName().".values set data='".$data."' where id="."$value->id;";
    }
  }
}
DB::unprepared($sql);

但这段代码不是一个好习惯!所以我的问题是

有更好的ORM方式来做到这一点吗？!

这是一个简单的方法.

$values = Value::where('project_id', $id)->update(['data'=>$data]);
