How to Perform Database Seeding in Laravel

In the past, I have published the article How to Seed the Database in PHP using Faker Library. While researching this topic, I found that Laravel also uses the same library for seeding the database. As I have written an article on this topic for PHP, I decided to write a post on database seeding in Laravel. Unlike plain PHP, Laravel uses its own flow to seed the database.

What is Database Seeding?

Database seeding is the process of filling your database tables with the test data programmatically. With this approach, one can insert thousands of fake entries into the database within a few minutes. It is an efficient way rather than doing it manually. You may want dummy data to test out your application and seeding the database programmatically saves you a ton of time.

Faker Library

Faker is an open-source library that generates fake data for your application’s database. Using Faker, one can insert thousands of entries in the database in a couple of minutes. This library saves a boring data entry job for developers. You can get almost any kind of data you want. The library generates a fake email, name, mobile number, words, sentences, paragraphs, random numbers, etc. You may read more about the library in the documentation.

Under the hood, Laravel uses a Faker library for database seeding. Laravel installs this library at its core. You don’t need to install it separately. All you need to do is follow the steps for the seeding and you’re done.

Getting Started

To get started, I’ll create a customers table with the column’s name, email, identification_number, and bio. We will see the process of seeding the single table. In the same way, one can seed as many tables as they want.

Create a migration for customers table using the command:

php artisan make:migration create_customers_table

Open the migration file and add the columns to the up() method as shown below.

public function up()
    Schema::create('customers', function (Blueprint $table) {

Run the migrate command which will create a customers table in your database.

php artisan migrate

Next, create a Customer model which maps to the customers table.

php artisan make:model Customer

Database Seeding in Laravel

Seeding a database in Laravel requires you to perform the following steps.

  • Writing seeders
  • Create a model factory
  • Run seeders

Writing Seeders

If you look at the Laravel filesystem, you would find the database/seeders directory. All seed classes are located inside this directory. A seed class has the run() method where you can write logic to insert the data in the table.

Make a seed class CustomerSeeder using the command:

php artisan make:seeder CustomerSeeder

After executing this command, you should see the CustomerSeeder.php file placed under the database/seeders folder. Open this file and to the run() function add the below code.

public function run()

Here I am calling the Customer factory which I’ll create in the next step. Notice I passed the value as 50 to the count() method. It means 50 rows should be inserted into the customers table.

Creating Model Factories

The code I have written in CustomerSeeder will look for a Customer factory to get the test data. It means we have to create a model factory called CustomerFactory. Run the below command to create the model factory.

php artisan make:factory CustomerFactory

This command will create a CustomerFactory.php inside the database/factories directory. Open this file, the definition() method would generate test data as follows.

public function definition()
    return [
        'name' => $this->faker->name(),
        'email' => $this->faker->email(),
        'identification_number' => $this->faker->randomNumber(9, true),
        'bio' => $this->faker->paragraph(),

The above array returns a random name, email, 9-digit number, and text for bio.

Running Seeders

We have written the CustomerSeeder and CustomerFactory. Now run the CustomerSeeder using the command below.

php artisan db:seed --class=CustomerSeeder

After this, check your customers table, it should have the 50 dummy entries inserted.

The above command runs a single seeder which we passed explicitly. Let’s say you want to create multiple seeders and run all of them using a single command. In such cases, you should call your seeders from the DatabaseSeeder which is found in the same database/seeders directory.

public function run()
        // next seeder

The user can create as many seeders as per their requirements and call them from this run() method.

Finally, run the seeders using the command below.

php artisan db:seed

It will call all seeders from the run method and execute it.

I hope you understand database seeding in Laravel. This should help you to fill up the database with tons of entries to test your application.

  1. I have successfully migrated my database and run db:seed but it returning without my database, with a message “seeding database”

  2. Hi
    i see many YouTube video and visit other website but I cannot found solution for factory and seeder. But i see you website and i use you method for to create seeders and factories. My problem solve. you method is to much easy, each and every thing describe step by step. Thank you very much to solve my problem.
