Generate dummy data in Laravel using Model Factory

Mar 16, 2018 Janaki Mahapatra, Laravel

Here are the steps needed to create dummy data

Lets create a model called Sample with migration file, using php artisan command
```
php artisan make:model Sample -m
```
Run the migration by
```
php artisan migrate
```
Generate a factory
```
php artisan make:factory SampleFactory --model=Sample
```
The new factory will be placed in your database/factories directory.

Open the SampleFactory class and add

$factory->define(App\Sample::class, function (Faker $faker) {
    return [
        'name' => $faker->name,
        'email' => $faker->unique()->safeEmail,
        'phone' => $faker->phoneNumber,
        'description' => $faker->text(200)
    ];
});

Create a seeder by using artisan command

php artisan make:seeder SamplesTableSeeder

Open the SamplesTableSeeder class file

use Illuminate\Database\Seeder;

class SamplesTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        factory(App\Sample::class,100)->create();
    }
}
/*
Where 
App\Sample => is the model class
100 => number of rows 
*/

Once the seeder is ready, we need to regenerate Composer's autoloader using the dump-autoload command:

composer dump-autoload

then run either

php artisan db:seed // to run all the seeder classes

php artisan db:seed --class=SamplesTableSeeder // for a single class

Now you can see the records in samples table.
