can I use traits to simplify factories for polymorphic relationships

Here's an example of how you can use traits to simplify factories for polymorphic relationships:

php
// UserableFactory
class UserableFactory extends Factory
{
    public function definition()
    {
        return [
            'name' => $this->faker->name,
            'email' => $this->faker->email,
        ];
    }
}

// PostFactory
class PostFactory extends Factory
{
    use UserableFactory;

    public function definition()
    {
        return array_merge(parent::definition(), [
            'title' => $this->faker->sentence,
        ]);
    }
}

// CommentFactory
class CommentFactory extends Factory
{
    use UserableFactory;

    public function definition()
    {
        return array_merge(parent::definition(), [
            'body' => $this->faker->paragraph,
        ]);
    }
}

In this example, the `UserableFactory` defines common attributes and methods for both `Post` and `Comment` models. The `PostFactory` and `CommentFactory` then extend `UserableFactory` and add their own specific attributes and methods.

This approach simplifies the process of defining factories for polymorphic relationships by allowing you to reuse common attributes and methods across multiple models.

Using Traits with Polymorphic Relationships

php
// UserableTrait
trait UserableTrait
{
    public function userable()
    {
        return $this->morphTo();
    }
}

// UserFactory
class UserFactory extends Factory
{
    use UserableTrait;

    public function definition()
    {
        return [
            'name' => $this->faker->name,
            'email' => $this->faker->email,
        ];
    }
}

// PostFactory
class PostFactory extends Factory
{
    use UserableTrait;

    public function definition()
    {
        return array_merge(parent::definition(), [
            'title' => $this->faker->sentence,
        ]);
    }
}

// CommentFactory
class CommentFactory extends Factory
{
    use UserableTrait;

    public function definition()
    {
        return array_merge(parent::definition(), [
            'body' => $this->faker->paragraph,
        ]);
    }
}

In this example, the `UserableTrait` defines the polymorphic relationship between a `User` model and a `Userable` model. The `UserFactory`, `PostFactory`, and `CommentFactory` then use this trait to set up the polymorphic relationship.

This approach simplifies the process of defining polymorphic relationships by allowing you to reuse the same trait across multiple models.
