Hello Geek, In Laravel, you can set the default value for a model’s attribute by defining a default value in the migration file that creates the table for the model.

You can use the $table->string('attribute_name')->default('default_value'); syntax within the up() method of the migration to define the default value.

Here’s an example of how you might define a default value for a model’s status attribute:

Install Laravel

composer create-project laravel/laravel example-app

Create Migration

php artisan make:migration create_posts_table

Then, add the following code to the migration file.

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

class CreateUsersTable extends Migration
{
    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('email')->unique();
            $table->string('password');
            $table->string('status')->default('active');
            $table->rememberToken();
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('users');
    }
}

Then, simply run migration command to run.

php artisan migrate

Create Model

To create a model in Laravel, you can use the following steps:

  1. Open the terminal and navigate to the root directory of your Laravel project.
  2. Run the following command to generate a new model:
php artisan make:model ModelName
  1. This will create a new model file in the ‘app‘ directory with the name ModelName.php.
  2. Open the model file and add the following code to define the table name for the model:
protected $table = 'table_name';
  1. If you want to define relationships between models, you can use the ‘hasOne‘, ‘hasMany‘, ‘belongsTo‘, or ‘belongsToMany‘ methods.
  2. Finally, you can use the model to perform database operations, such as creating, reading, updating, and deleting records.

Example:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    protected $table = 'users';

    public function posts()
    {
        return $this->hasMany('App\Post');
    }
}

 Create Route

This step requires us to create one route for testing. Let’s add the following route to the web.php file.

<?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']);

Create Controller

In this step, we’ll make a PostController with index() to create and display posts.

<?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'));
    }
}

Create Blade File

                <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>
  
</div>
      
</body>
      
</html>

Run Laravel App:

php artisan serve

Now, Go to your web browser, type the given URL and view the app output:

http://localhost:8000/demo-posts

All the best nerd!
