Laravel 8 Generate fake data using Faker and Factory
Using Factory and Faker that ships with Laravel, It’s not that hard to generate thousands of posts in a matter of seconds. With a bit of setup, It can be done. I am going to show you how you can generate fake data using Faker and Factory in Laravel.
Following this step-by-step tutorial is easy. There is also an easier way of doing it shown at the end of this article.
Requirements:
- Make sure you have a fresh install of laravel
- Create a database and inform .env
Create a Address model
php artisan make:model Address -mAdd fields to the Address migration
Schema::create('addresses', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->integer('mobile');
$table->integer('nid');
$table->string('address');
$table->timestamps();
});Run the migration
php artisan migrateCreate Address Factory
php artisan make:factory AddressFactory --model="Address"Go to database/factories/AddressFactory.php. There you will see AddressFactory already Created.
Put the following code right below. This is for the Address model, You can modify it for other models adding more fields as needed.
Here we are using faker to create name,mobile , nid and address fields
protected $model = Address::class;
public function definition()
{
return [
'name' => $this -> faker->name(),
'mobile' => $this -> faker->biasedNumberBetween(1,100000),
'nid' => $this -> faker->randomDigit(),
'address' => $this -> faker->address(),
];
}To test this, open up tinker:
php artisan tinkerRun the factory command:
Address::factory()->make();You should get a response similar to this:
=> App\Models\Address {#3583
name: "Rossie Williamson",
mobile: 39826,
nid: 5,
address: """
40790 Amber Flats Apt. 223\n
Eulastad, CO 91888
""",
}
This creates the Address model; it doesn’t actually save it to the database. To save it to the database, you can use create() instead of make().
Now we try to create 10 Address.Laravel makes this painless as well. Let’s look at it in tinker again.
Address::factory()->count(10)->create();
php artisan tinker
//Run This Command
>>> Address::factory()->count(10)->create();
[!] Aliasing 'Address' to 'App\Models\Address' for this Tinker session.
