Laravel Database Seeding Using faker And ModelFactories to generate Seeds
Example
1) BASIC SIMPLE WAY
Database-driven applications often need data pre-seeded into the system for testing and demo purposes.
To make such data, first create the seeder class
ProductTableSeeder
use Faker\Factory as Faker;
use App\Product;
class ProductTableSeeder extends DatabaseSeeder {
public function run()
{
$faker = $this->getFaker();
for ($i = 0; $i < 10; $i++)
{
$name = $faker->word;
$image = $faker->imageUrl;
Modelname::create([
'name' => $name,
'image' => $image,
]);
}
}
}
To call a be able to execute a seeder class, you have call it from the DatabaseSeeder class, Simply by passing the name of the seeder you wish to run:
use Illuminate\Database\Seeder;
class DatabaseSeeder extends Seeder {
protected $faker;
public function getFaker() {
if (empty($this->faker)) {
$faker = Faker\Factory::create();
$faker->addProvider(new Faker\Provider\Base($faker));
$faker->addProvider(new Faker\Provider\Lorem($faker));
}
return $this->faker = $faker;
}
public function run() {
$this->call(ProductTableSeeder::class);
}
}
Do not forget to run $ composer dump-autoload after you create the Seeder, since they are not automatically autoloaded by composer (unless you created seeder by artisan command $ php artisan make:seeder Name)
Now you are ready to seed by running this artisan command php artisan db:seed
2) USING Model Factories
First of all you to define a default set of attributes for each Model in App/database/factories/ModelFactory.php
Taking a User model as an exemple, This how a ModelFactory looks like
$factory->define(App\User::class, function (Faker\Generator $faker) {
return [
'name' => $faker->name,
'email' => $faker->email,
'password' => bcrypt(str_random(10)),
'remember_token' => str_random(10),
];
});
Now Create a table seeder php artisan make:seeder UsersTableSeeder
And add this
public function run()
{
factory(App\User::class, 100)->create()
}
then add this to the DatabaseSeeder
public function run()
{
$this->call(UsersTableSeeder::class);
}
This will seed the table with 100 records.
