Integrating Calculated Fields with Laravel Factory System

To integrate calculated fields with Laravel's factory system, you can use the `afterCreating` method in your factory to calculate the calculated field after the model is created. Here is an example:

php
use App\Models\Profile;
use Illuminate\Database\Eloquent\Factories\Factory;

class ProfileFactory extends Factory
{
    protected $model = Profile::class;

    public function definition()
    {
        return [
            'user_id' => factory(User::class),
            'weight' => $this->faker->randomNumber(3),
            'height' => $this->faker->randomNumber(3),
            'dob' => $this->faker->date,
        ];
    }

    public function afterCreating(Profile $profile)
    {
        $profile->bmi = $profile->weight / ($profile->height * $profile->height);
    }
}

In this example, the `afterCreating` method is called after the `Profile` model is created. It calculates the `bmi` field based on the `weight` and `height` fields.
