CRUD Laravel 8 Tutorial Example

Hay ..

Tutorial kali ini saya akan membagikan bagaimana cara CRUD (Create, Read, Update, Delete) sederhana dengan Laravel versi 8

Ikuti step by step nya ya atau bisa juga dipahami ^_^

Step 1 : Instalasi Laravel versi 8

laravel new demo-laravel, saya menggunakan perintah seperti itu. Lebih lengkapnya silahkan lihat documentasi dari situs resminya

1_1

Step 2 : Database Configuration

.env

5

Sesuaikan dengan pengaturan kalian masing-masing

Step 3 : Creata migration

php artisan make:migration create_posts_table --create=posts

2_1

Pada file "database/migrations" yang sudah kita buat, tambahkan untuk schema database nya 

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreatePostsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->longText('description');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
    }
}

php artisan migrate

Step 4 : routes/web.php

use App\Http\Controllers\PostController;

Route::resource('posts',PostController::class);

Step 5 : Membuat Controller dan Model

php artisan make:controller PostController --resource --model=Post

Dan akan ada sebuah file "app/Http/Controllers/PostController.php" karena kita menggunakan --resource, maka akan otomatis kita sudah mempunyai methods yang siap dipakai didalam PostController.php nya yaitu :

  1. index ()
  2. create ()
  3. store ()
  4. show ()
  5. edit ()
  6. update ()
  7. destroy ()

pada app/Http/Controllers/PostController.php, isi seperti ini

<?php

namespace App\Http\Controllers;

use App\Models\Post;
use Illuminate\Http\Request;

class PostController extends Controller
{
 
    public function index()
    {
        $posts = Post::latest()->paginate(5);
        return view('posts.index', compact('posts'))
            ->with('i', (request()->input('page', 1) - 1) * 5);
    }

    public function create()
    {
        return view('posts.create');
    }

    public function store(Request $request)
    {
        $request->validate([
            'title' => 'required',
            'description' => 'required',
        ]);

        Post::create($request->all());

        return redirect()->route('posts.index')
            ->with('success', 'Post created successfully.');
    }

    public function show(Post $post)
    {
        return view('posts.show', compact('post'));
    }

    public function edit(Post $post)
    {
        return view('posts.edit', compact('post'));
    }

    public function update(Request $request, Post $post)
    {
        $request->validate([
            'title' => 'required',
            'description' => 'required',
        ]);

        $post->update($request->all());

        return redirect()->route('posts.index')
            ->with('success', 'Post updated successfully');
    }
    
    public function destroy(Post $post)
    {
        $post->delete();

        return redirect()->route('posts.index')
            ->with('success', 'Post deleted successfully');
    }
}

Kemudian pada app/Models/Post.php kita tambahkan seperti ini

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use HasFactory;

    protected $fillable = [
        'title', 'description',
    ];
}

Untuk views nya sendiri, disini saya membuat sebuah folder dengan nama "posts" sehingga terlihat rapih 

Kurang lebih seperti ini untuk struktur diviews nya

  1. layout.blade.php
  2. index.blade.php
  3. create.blade.php
  4. edit.blade.php
  5. show.blade.php
