We will look at an example of laravel model set default value. we will help you to give an example of how to add default value in laravel model. Alright, let us dive into the details.

You can use this example with laravel 6, laravel 7, laravel 8, laravel 9, laravel 10 and laravel 11 versions.

Step 1 : Install Laravel

first of all we need to get fresh Laravel version application using bellow command, So open your terminal OR command prompt and run bellow command:

composer create-project laravel/laravel example-app

Step 2: Create Migration

here, we will create migration for posts table, so let's run the below command and run migration.

php artisan make:migration create_posts_table

Then, let's put the below code on migration file.

database/migrations/2022_06_02_132801_create_posts_table.php

<?php
  
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
  
return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->text('body');
            $table->timestamps();
        });
    }
  
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
    }
};

Then, simply run migration command to run.

php artisan migrate

Step 3: Create Model

Here, we will create Post model and we will set title fields default value using $attributes. so let's add the below code:

app/Models/Post.php

<?php
  
namespace App\Models;
  
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
  
class Post extends Model
{
    use HasFactory;
  
    /**
     * Write code on Method
     *
     * @return response()
     */
    protected $fillable = [
        'title', 'body'
    ];
  
    /**
     * The model's default values for attributes.
     *
     * @var array
     */
    protected $attributes = [
        'title' => 'Default Title',
    ];
}

Step 4: Create Route

In this is step we need to create one route for testing. let's add the below route on web.php file.

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\PostController;
  
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
  
Route::get('demo-posts', [PostController::class,'index']);

Step 5: Create Controller

in this step, we need to create PostController with index() to create posts and display posts.

Add the below code on controller file.

app/Http/Controllers/PostController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Models\Post;
  
class PostController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
        Post::create([
            'body' => 'Post Body Added'
        ]);
  
        Post::create([
            'title' => 'Manually Title Added',
            'body' => 'Post Body Added'
        ]);
  
        $posts = Post::latest()->get();   
  
        return view('posts', compact('posts'));
    }
}

Step 6: Create Blade File

in this step, we will create posts.blade.php and display all posts on it.

Add the below code on controller file.

resources/views/posts.blade.php

                <th>Body</th>
            </tr>
        </thead>
        <tbody>
            @foreach($posts as $post)
                <tr>
                    <td>{{ $post->id }}</td>
                    <td>{{ $post->title }}</td>
                    <td>{{ $post->body }}</td>
                </tr>
            @endforeach
        </tbody>
    </table>
