Using `on_delete=models.SET_NULL` ensures that if you remove an image or hero link from your admin interface, the `image` or `hero_cta_link` fields on your Homepage will be set to null, but the rest of the data will be preserved. Read the [Django documentation on the `on_delete` attribute](django.db.models.ForeignKey.on_delete) for more details.
