Question

I’m encountering an issue when trying to display student data in a Laravel view. When I attempt to access the id property of the student object in the view, I get an ErrorException: Attempt to read property ‘id’ on bool.

This is my Controller

public function show($id)
{
    $mahasiswa = Mahasiswa::with('mataKuliah')->find($id);
    $mataKuliah = MataKuliah::all();

    if (!$mahasiswa) {
        return redirect()->route('daftar-krs')->with('error', 'Student not found');
    }

    return view('Krs.Index', compact('mahasiswa', 'mataKuliah'));
}

View

<!DOCTYPE html>

<head>
    @include('Template.head')
</head>
