php artisan make:migration create_posts_tableThen, let’s put the below migration table code in migration file.
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
return new class extends Migration
{
/**
* Run the migrations.
*/
public function up(): void
{
Schema::create('posts', function (Blueprint $table) {
$table->id();
$table->string('title');
$table->text('body');
$table->timestamps();
});
}
/**

*/
public function down(): void
{
Schema::dropIfExists('posts');
}
};

Step 3: Create Model
Here, we will create Post model and we will set title fields default value using $attributes.
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Post extends Model
{
protected $fillable = [
'title', 'body'
];
protected $attributes = [
'title' => 'Defult post title'
];
}
Step 5: Create Route
In this step we need to create one route for testing purpose. Add route in web.php
<?php
use App\Http\Controllers\PostController;
use Illuminate\Support\Facades\Route;
Route::get('/', function () {
return view('welcome');
});
Route::get('testing', [PostController::class, 'index']);
Step 5: Create Controller
In this step, we need to create PostController with index() to create posts.
<?php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use App\Models\Post;
use Illuminate\Http\Request;
class PostController extends Controller
{
public function index(Request $request)
{
Post::create([
'body' => 'Post body 1',
]);
Post::create([
'title' => 'Manually addded title',
'body' => 'Post body 2'
]);
$posts = Post::latest()->get();
dd($posts);
}
}
Output:
array:2 [▼ // app\Http\Controllers\PostController.php:23
0 => array:3 [▼
"id" => 27
"title" => "Defult post title"
"body" => "Post body 1"
]
1 => array:3 [▼
"id" => 28
"title" => "Manually addded title"
"body" => "Post body 2"
]
]I hope this tutorial help you.
