OrderBy在Eloquent查询中修复为asc

Question

我尝试在Eloquent查询中转换以下SQL请求：

SELECT  locals.*
FROM prises JOIN locals
  ON prises.liaison_id = locals.id
GROUP BY locals.id
ORDER BY COUNT(liaison_id);

我写了这个：

return $query->select('locals.*')
                ->from('prises')
                ->join('locals', function($join) {
                    $join->on('prises.liaison_id', '=', 'locals.id');
                })
                ->orderBy(DB::raw('count(prises.liaison_id)', 'DESC'))
                ->groupBy('locals.id');

在我的php页面上，它可以运行，但此查询正在运行：

select "locals".* from "prises" 
inner join "locals" on "prises"."liaison_id" = "locals"."id" 
group by "locals"."id" 
order by count(prises.liaison_id) asc limit 100 offset 0

我的Asc / Desc是固定的，我不知道为什么。使用DB :: raw阻止我吗？

提前致谢。
