How to insert data to database using seeder in Laravel? - php

Question

I have a problem with seeder. My data not insert to the database. The table customers are created but data not insert to database. Below I show me code. I use
php artisan migrate:fresh --seed
Migration
public function up()
{
Schema::create('customers', function (Blueprint $table) {
$table->id();
$table->string('first_name', 20);
$table->string('last_name', 30);
$table->string('email')->unique();
$table->string('phone_number')->unique();
$table->timestamps();
});
}
Model
class Customer extends Model
{
use HasFactory;
protected $fillable = [
'first_name',
'last_name',
'email',
'phone_number'
];
}
Factory
class CustomerFactory extends Factory
{
/**
* Define the model's default state.
*
* #return array<string, mixed>
*/
public function definition()
{
return [
'first_name' => fake()->firstName(),
'last_name' => fake()->lastName(),
'email' => fake()->unique()->safeEmail(),
'phone_number' => fake()->unique()->phoneNumber()
];
}
}
Seeder
class CustomersTableSeeder extends Seeder
{
/**
* Run the database seeds.
*
* #return void
*/
public function run()
{
Customer::factory(20)->create();
}
}
Now show me error

Answer 1

Within the DatabaseSeeder class, you have to call the method to execute additional seed classes.
/**
* Run the database seeders.
*
* #return void
*/
public function run()
{
$this->call([
CustomersTableSeeder::class,
]);
}
As per the official doc:
Within the DatabaseSeeder class, you may use the call method to
execute additional seed classes. Using the call method allows you to
break up your database seeding into multiple files so that no single
seeder class becomes too large. The call method accepts an array of
seeder classes that should be executed:
