问题描述
试图从我的数据库中获取描述.查询返回结果,但我想将结果排序为只显示投票最高的那个.
Trying to fetch a description from my database. The query returns the result but I would like to order the result to only show the one with the highest vote.
投票应该由upvoted
列减去downvoted
列
$description = UnitDescription::find()
->where(['id_unit' => $model->id])
->orderBy([
'upvoted - downvoted' => SORT_DESC //Need this line to be fixed
])
->one();
我希望有人可以编写查询的这一部分 - 谢谢
I was hoping someone might have a way to write this part of the query - Thanks
