How To Add Default Value Of Column In Laravel Migration

In this article, we will explore how to add default values to columns in Laravel 10 migrations, although the information applies to Laravel 8 and 9 as well. Specifically, we will focus on adding default values to columns using Laravel migrations.

Laravel's migration system offers a convenient default() method that allows you to specify the default value for a column. Additionally, you can make use of the nullable() method to set a column as nullable.

Let's dive into the process of adding default values in Laravel 10 migrations, whether you need to set default values for an existing column, work with boolean defaults, or even use the current timestamp as a default. This knowledge is equally applicable to Laravel 8 and 9

Create Migration Command:

php artisan make:migration create_posts_table

Migration:

<?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')->nullable();
            $table->text('description')->default('This is test description');
            $table->boolean('is_active')->default(0);
            $table->timestamps();
        });
    }
 
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
    }
}
