Tip 1. Use updateOrCreate() to avoid double-seeding
Imagine this seeder code, and imagine if for some reason this seeder would be launched more than once:
public function run()
{
$items = [
['id' => 1, 'title' => 'Administrator'],
['id' => 2, 'title' => 'Simple user'],
];
foreach ($items as $item) {
Role::updateOrCreate(['id' => $item['id']], $item);
}
}
Running a seeder by class
php artisan db:seed --class=UsersTableSeeder
Run Seeder Class From Migration
public function up()
{
Schema::create('themes', function (Blueprint $table) {
$table->increments('id');
$table->text('name');
});
Artisan::call('db:seed', [
'--class' => ThemesTableSeeder::class
]);
}
Seeder Factory with Relationship: Use Parent’s Factory
If you use Factories for your seeds, how do you set up relationships between two models? For example, you need to seed 10 companies and 10 contacts within those companies? database/factories/CompanyFactory.php
$factory->define(App\Contact::class, function (Faker\Generator $faker) {
return [
'company_id' => factory('App\Company')->create()->id,
'first_name' => $faker->firstName(),
'last_name' => $faker->lastName,
'phone1' => $faker->phoneNumber,
'phone2' => $faker->phoneNumber,
'email' => $faker->email,
'skype' => $faker->word,
'address' => $faker->address,
];
});
DatabaseSeeder for Local and Production
class DatabaseSeeder extends Seeder
{
/**
* Seed the application's database.
*
* @return void
*/
public function run()
{
if (app()->environment() == 'production') {
$this->call(ThemesTableSeeder::class);
$this->call(LanguagesTableSeeder::class);
} else {
$this->call(UsersTableSeeder::class);
$this->call(ModulesTableSeeder::class);
$this->call(ThemesTableSeeder::class);
$this->call(LanguagesTableSeeder::class);
}
}
}
