php – What is database seeding in Laravel?

Posted by: admin July 12, 2020 Leave a comment


I use Laravel framework and I have recently been informed that there is something named database seeding which produces a fake dataset for our tests. Is my understanding correct?

Well that’s pretty much odd. How it works? How it knows which type of data do I need in X column of database? And how it generates it?

Also, Can’t I make a seed of my real dataset (something like an export)? You know, I don’t know English very well, that’s why I cannot understand the concept of seed in database field.

How to&Answers:

Usually you’re using model Factories and faker to create fake data (with relations etc) for developing and testing your app.

If you want to seed real data, just use commands to import dump. Or, if your data is something like table with countries, create seeder which inserts the real data without using faker or model factory.

Also, you can use some package to create seeder from real data.

Yes, Laravel comes with the very great & popular package named – Faker. You can write this example, using Faker and generate 10 users like this (inside DatabaseSeeder.php):

use DB;
use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;

use Faker\Factory as Faker;

class DatabaseSeeder extends Seeder
     * Run the database seeds.
     * @return void
    public function run()
        $faker = Faker::create();
        foreach (range(1,10) as $index) {
                'name' => $faker->name,
                'email' => $faker->email,
                'password' => bcrypt('secret'),

That’s it – $faker->name will generate a random person name, and $faker->email – a random email. After running command php artisan db:seed your database get populated with some random entries.

You can find this package inside your composer.json file under require-dev:

"require-dev": {
    "fzaninotto/faker": "^1.6", // <------- here
    "mockery/mockery": "0.9.*",
    "phpunit/phpunit": "~5.0",
    "symfony/css-selector": "3.1.*",
    "symfony/dom-crawler": "3.1.*",
    "laracasts/testdummy": "~2.0"

Faker can generate lots of data, from which some are given below:


Hope this helps!
