I want to ask, why can the results be with other users like the table below for the score, each score must be different. So id_student = 15 with id_student = 12 the score is 80 the same for all, it should be different from that in the database it should be id_student = 15 the score is 100 which is correct as in the database in the Assignment_details table below:

Table database in MySQL

Code:

Controller:

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.index', compact('userAssignments'));
    }

Model:

protected $fillable = [
        'id_id',
        'title',
        'assign_date',
        'due_date',
        'file_asg',
        'id_subject',
    ];

    public function assignments(){
        return $this->belongsTo(AssignmentDetail::class, 'id_id','id_assignment');
    }

    public function nulls(){
        return $this->hasMany(AssignmentDetail::class, 'id_assignment', 'id_id')
                ->where('assignment_details.id_student', '=', Auth::user()->id)
                ->first() === null;
    }

What is the solution for id_student = 15 and id_student = 12 so that they can be on the web according to the database?

CodePudding user response：

I think in your model should have One To Many relationship that's mean hasMany, every user may have many score. if right then you must have:

public function assignments(){
    return $this->hasMany(AssignmentDetail::class, 'id_id','id_assignment');
}
