Laravel: Two Ways to Seed Data with Relationships

While seeding data, it’s common to have one class for each database table. But what if there are relationships? I will show you two ways you can deal with it.

Imagine we have this simple database structure – database contacts and contact_companies (taken from our Contact Management module in QuickAdminPanel):

contact management laravel

How to seed data in both tables?
Of course, we will use Faker library, but still – there are a few ways to implement it.

First, let’s define our factories.


And database/factories/ContactFactory.php:

Now, as you can see, there’s no contacts.company_id defined. Here’s where we have a few options:

Version 1. Create contacts inside of company seed

Let’s create a company seeder:

And then fill the file database/seeds/CompanySeed.php with this:

Basically, we’re creating 10 companies, and for each of them we’re creating one contact, using Eloquent relationship in app/ContactCompany.php:

Version 2. Create company along with the contact

The other way around would be to use seed for Contacts.

And then add only this line in database/seeds/ContactSeed.php:

You’re probably wondering where the relationship would come from? We can create a “parent” entry directly in the factory! Like this:


See the first field? We’re using parent factory and creating a company “on-the-fly”.

That’s it, isn’t it simple?
In official Laravel documentation you can find more information about seeding and using factories with Faker.
