Laravel:columnize() 必须是数组类型，给定字符串，调用

Question

我想在更新记录时调用此查询而不是 ID，但我收到错误消息 columnize() 必须是数组类型，给定字符串，在 中调用

$user = Attendances::find(DB::raw('concat (firstname, " ",lastname)'), 'like', Input::get('student_name'))->where('section_name', 'like', Input::get('section_name'))->where('teacher_id', '=', Auth::user()->id)->where('subject_code', 'like', Input::get('subject_code'));

请帮忙:(

第一种方法应该是where()同样，因为 find()仅适用于主键。另外最后应该打电话get()或 first()执行查询:

$user = Attendances::where(DB::raw('concat (firstname, " ",lastname)'), 'like', Input::get('student_name'))
       ->where('section_name', 'like', Input::get('section_name'))
       ->where('teacher_id', '=', Auth::user()->id)
       ->where('subject_code', 'like', Input::get('subject_code'))
       ->first();
