use App\Http\Controllers\KriteriaController;
use App\Http\Controllers\AlternatifController;
Route::resource('kriteria', KriteriaController::class)->except('show');
Route::resource('alternatif', AlternatifController::class)->except('show');

View alternatif dapat memakai pola yang sama dengan kriteria.

Tambahkan Menu
Pada navbar layouts/app.blade.php, tambahkan:
<a class="nav-link text-white" href="{{ route('kriteria.index') }}">Kriteria</a>
<a class="nav-link text-white" href="{{ route('alternatif.index') }}">Alternatif</a>
Data Awal
Data awal sudah dibuat melalui AhpSeeder pada bagian sebelumnya.
Kriteria:
C1 - Harga
C2 - Kualitas
C3 - Pelayanan
Alternatif:
A1 - Supplier A
A2 - Supplier B
A3 - Supplier C
Seeder juga sudah membuat seluruh pasangan perbandingan kriteria dan alternatif dengan nilai awal 1.
CRUD pada bagian ini digunakan untuk menambah, mengubah, atau menghapus data kriteria dan alternatif.
Jika jumlah kriteria atau alternatif diubah melalui CRUD, pasangan perbandingan untuk data baru akan diisi pada halaman perbandingan pada langkah berikutnya.
Checkpoint
Pastikan tambah, edit, dan hapus kriteria serta alternatif berjalan normal.
