Laravel 按别名排序

Question

在下面的代码中，如果我删除“解决方法”，则找不到用户名列，如何在 get 命令之前设置别名？有窍门吗？

    //Select
    $qb = DB::table('log as l');

    //Joins
    $qb->join('user as u', 'l.user_id', '=', 'u.id');

    //Orders        
    if($sort[0]["field"]=="user_name")// This is a workaround for my problem
        $sort[0]["field"] = "u.name";

    $qb->orderBy($sort[0]["field"],$sort[0]["dir"]);

    //Wheres
    Data::applyFilter($qb,$filters);

    $total = $qb->count("l.id");

    $qb->skip($skip)
       ->take($take);

    $result = $qb->get(array("l.id", "l.action", "l.entity_type", "l.entity_id", "u.name as user_name", "l.datetime"));

Answer 1

在documentation有

$users = DB::table('users')->select('name as user_name')->get();

如果你设置一个键值变量而不是“user_name”它应该做你想做的事？
