yii2 ActiveRecord通过计算查找OrderBy

尝试从我的数据库中获取描述.查询返回结果,但我想命令结果只显示投票率最高的结果.

投票应按upvoted列减去的downvoted列计算

$description = UnitDescription::find()
   ->where(['id_unit' => $model->id])
   ->orderBy([
      'upvoted - downvoted' => SORT_DESC //Need this line to be fixed
   ])
   ->one();

我希望有人可能有办法写这部分查询 - 谢谢

你应该尝试:

$description = UnitDescription::find()
    ->where(['id_unit' => $model->id])
    ->orderBy(['(upvoted - downvoted)' => SORT_DESC])
    ->one();
