How to seed related data during migration in Laravel?

Question

I have a table clients and a table contracts. In my Client model I have

public function contract()
    {
        return $this->hasOne(
            'App\Models\Contract',
            'client_id',
            'id'
        );
    }

I don't want to have any client without a contract in my database. When I seed my clients, using the factory with faker data, I want to create contracts that are mapped to client using the foreign key user_id on the contract.

Yes it does, thank you. In my case it is `save()` instead of `saveMany()`, but I already tested it and it is working. Quick question to learn to avoid asking duplicate questions in the future, because I searched a solution before I asked. Did I need to know that this is called "Seeding Relationships"? — PeterPan, May 05 '22 at 12:07
Would help for being more specific in searches. Is it a must? No. probably not. — geertjanknapen, May 05 '22 at 12:09

make sure to make a factory for each table and then you can simply do something like

        Client::factory()
        ->count(3)
        ->has(Contract::factory()->forUser()->create())
        ->create();

Notice: check your relations in your models then it should be fine :)

This is what worked for me:

App\Models\Client::factory(10)->create()->each(function ($client) {
    $client->contract()->save(Contract::factory()->make());
});
