`move_posts.new_topic_moderator_post.one`를 편집하려고 합니다.
왜 `topic_link`는 유효한데 `topic_title`이나 `topic_name`은 유효하지 않을까요?
# [%{topic\_title}](%{topic\_link})
사용할 수 있는 다른 키가 있을까요? 감사합니다.

아니요, `topic_link`만 사용할 수 있으며, 키는 [코드에 전달된 값](https://github.com/discourse/discourse/blob/main/app/models/post_mover.rb#L437-L445)으로 제한됩니다.

아, 그렇군요. 이해가 갑니다. 감사합니다.

재미있게도 `topic_link`가 실제로 내가 하려고 했던 것(`[%{topic_title}](%{topic_link})`)이었습니다.
따라서 단순히 `# %{topic_title}`만 사용해도 예상대로 변경되었습니다.
