Laravel - Database - Polymorphic Relationships
Polymorphic relationships may also be created using factories. Polymorphic "morph many" relationships are created in the same way as typical "has many" relationships. For example, if a App\Models\Post
model has a morphMany
relationship with a App\Models\Comment
model:
use App\Models\Post;
$post = Post::factory()->hasComments(3)->create();
