php - 拉维尔 5.4 : How to order by count(column) in eloquent?

Question

我正在尝试显示按assigned_to 票数最多的受让人姓名。

$accesses = Access::where('state','=','Assigned');

$all = Report::where('state', '=', 'Assigned')
               ->union($accesses)
               ->orderBy('count(assigned_to)') //THIS IS WRONG
               ->get();

Answer 1

你必须使用 DB::raw 来获取它

$all = Report::where('state', '=', 'Assigned')
            ->select(DB::raw('count(reports.assigned_to) as assigned_to'))
            ->union($accesses)
            ->orderBy('assigned_to','DESC') 
            ->get();
