Example
You may want to re-seed your database without affecting your previously created seeds. For this purpose, you can use firstOrCreate in your seeder:
EmployeeType::firstOrCreate([
'type' => 'manager',
]);
Then you can seed the database:
php artisan db:seed
Later, if you want to add another type of employee, you can just add that new one in the same file:
EmployeeType::firstOrCreate([
'type' => 'manager',
]);
EmployeeType::firstOrCreate([
'type' => 'secretary',
]);
And seed your database again with no problems:
php artisan db:seed
Notice in the first call you are retrieving the record but doing nothing with it.
