过滤 Laravel 用户以仅显示上传的用户-PHP中文网问答

我想问，如何在用户1上将文件上传到网络，但仅将其附加到用户1，而目前它也附加到用户2，我的编码错误。

就像下面的示例图片一样：图片网络

看一下图片，如果已经上传了，在“Bahasa Indonesia”SUBJECT 中将其状态改为 Submitted，但是对于用户 2 来说还没有上传，但是也变成了 Submitted，用户 2 的状态肯定是 Waiting因为还没有上传。这里附上我在用户1上上传的mysql：图像MySqli

AssignmentStudentController

public function DataAssignment(){
    $userAssignments = Assignment::join('subjects', 'assignments.id_subject', '=', 'subjects.id_sub')
        ->join('class_infos', 'subjects.id_class', '=', 'class_infos.id')
        ->join('class_details', 'class_infos.id', '=', 'class_details.id_class')
        ->where('class_details.id_user', '=', Auth::user()->id)
        ->get();

    return view('student.assignment.data_assignment', compact('userAssignments'));
}
