Laravel seeder migration

Creating a Seeder

You can generate a new seeder using the `make:seeder` Artisan command:

php artisan make:seeder UsersTableSeeder

This will create a new seeder class in the `database/seeders` directory.

Defining Seeding Logic

In the generated seeder class, you can define the data to be inserted into the database. For example:

php
public function run()
{
    DB::table('users')->insert([
        'name' => 'John Doe',
        'email' => '[email protected]',
        'password' => bcrypt('secret'),
    ]);
}

Running Seeders

To seed your database, use the `db:seed` command:

php artisan db:seed

This will execute the `run()` method of all seeder classes.

Combining Migrations and Seeders

You can combine migrations and seeders by calling a seeder from within a migration's `up()` method:

php
public function up()
{
    Schema::create('users', function (Blueprint $table) {
        $table->id();
        $table->string('name');
        $table->string('email')->unique();
        $table->timestamp('email_verified_at')->nullable();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
    });

    $this->call([
        UsersTableSeeder::class,
    ]);
}

This will create the `users` table and immediately seed it with data from the `UsersTableSeeder` class.

To rollback the migration and remove the seeded data, use the `migrate:rollback` command.

By combining migrations and seeders, you can easily manage your database schema and populate it with initial data in a version-controlled manner.
