How to see only uploaded users in laravel?-CodePudding

I want to ask, how do I upload a file to the web on user 1 but only attach it to user 1, whereas currently it is also attached to user 2, my coding is wrong.
like the example image below: Images Web
If you look at the picture, if it has been uploaded, change it to Submitted status in the "Bahasa Indonesia" SUBJECT, but for user 2 it hasn't been uploaded, but it has also become Submitted, user 2's status must be Waiting because it hasn't been uploaded yet. And here is attached my mysql uploaded on user 1: Images 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'));
}

AssignmentStudentController.php

CodePudding user response：

You can check by defining a new method in addition to the assignments method in your model:

class Assignment extends Model
{
    public function assignments()
    {
        return $this->hasMany(<YOUR_ASSIGNMENTS_TABLE_NAME>::class, 'id_assignment', 'id_id');
    }

    // new method
    public function checkStudentAssignmentIsNull()
    {
        return $this->hasMany(<YOUR_ASSIGNMENTS_TABLE_NAME>::class, 'id_assignment', 'id_id')
            ->where('<YOUR_ASSIGNMENTS_TABLE_NAME>.id_student', Auth::user()->id)
            ->first() === null;
    }
}

And when using, you can do !$data->checkStudentAssignmentIsNull() instead of !empty($data->assignments->id_student).

I see your tables more clearly now:

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