Intead of < sign inside filter method you should use __lt lookup attached to field name:

posts = Post.objects.filter(publish__lt=timezone.now() - timedelta(days=days))

FieldError at /account/ Cannot resolve keyword 'publish_lt' into field. Choices are: author, author_id, body, id, location, publish, title

@JestemPokrowcem Double underscore, not single. That's how you access these methods.
