Laravel 8 + Tinker: How to create dummy data

Question

In previous Laravel version I use this in tinker:

php artisan tinker
factory(App\Banana::class, 3)->create();

But in Laravel 8, it gives this error: `PHP Error: Class 'Database/Factories/bananaFactory' not found

How to create dummy data in Laravel 8 using tinker please? Thank you.

Answer 1

You can try by this steps:

1. Inside your Banana Model added HasFactory like below:

<?php
namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Banana extends Model
{
    use HasFactory;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'title', 'description'
    ];
}

2. Create Factory

- php artisan make:factory BananaFactory --model=Banana

3. After generate BananaFactory go to that path then:

<?php
 
namespace Database\Factories;
 
use App\Models\Post;
use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;
 
class BananaFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = Banana::class;
 
    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            'title' => $this->faker->title,
            'description' => $this->faker->text,
        ];
    }
}

4. After that run this command:

 composer dump-autoload

5. then open the terminal and run:

php artisan tinker
Banana::factory()->count(3)->create()
