캘린더 RSVP 게시물

:information_source: Summary Creates short topic replies for RSVP events
:hammer_and_wrench: Repository Link GitHub - mariodsantana/discourse-calendar-rsvp-posts · GitHub
:open_book: Install Guide How to install plugins in Discourse

Features

  • Real-time notifications - Because RSVP events now create a reply post in the topic, every RSVP triggers notifications for topic watchers
  • Minimal clutter - Previous notification posts are deleted, so there’s a maximum of 2 posts at any time (1 history + 1 latest notification)
  • Complete history - All RSVP activity is preserved with timestamps in chronological order
  • Discourages flip-flopping - Timestamps make repeated RSVP changes visible

Configuration

The relevant site settings (in Admin > Settings > Plugins) mostly configure which RSVP changes should trigger a post - going, interested, not going, or removal of existing RSVP - and whether to trigger on RSVP changes to events that start in the past.

The remaining setting toggles history mode. With history mode disabled, only the latest notification post remains in the topic. With history mode enabled, the plugin manages an additional “history” comment as follows:

  • On the first RSVP, creates a simple notification post announcing the RSVP
  • On the second RSVP, transforms the first post into a timestamped history post, then creates a new notification post
  • On subsequent RSVPs, appends the RSVP to the history post with timestamp, deletes the previous notification post, and creates a new one

Settings

Name Description
calendar_rsvp_posts_on_new_going post on new “Going”
calendar_rsvp_posts_on_new_interested post on new “Interested”
calendar_rsvp_posts_on_new_not_going post on new “Not going”
calendar_rsvp_posts_on_removed_rsvp post when an RSVP is removed
calendar_rsvp_posts_allow_past_events whether to post for events that start in the past
calendar_rsvp_posts_enable_history maintain a timestamped history post (default: enabled)

Thanks for the plugin :+1:

Just a small question: is it possible to translate the responses into a file?

이 아이디어 좋아요. 히스토리 게시물에 CSV 파일을 다운로드할 수 있는 링크를 추가할 수 있겠네요. 그런 걸 생각하고 계신 건가요?

잘 표현하지 못했습니다 :sweat_smile: . 답변 알림을 어떻게 번역하면 되는지 알고 싶었어요. 알림이 영어로 되어 있어서 한국어로 설정하고 싶거든요.

ㅋㅋ - 이제 이해했어요. 현재 영어 텍스트가 소스 코드에 직접 들어가 있네요. 저는 디스커스에 초보이지만, 플러그인을 번역 가능하게 만드는 표준적인 방법이 분명 있을 거예요. 시간이 나면 한번 알아볼게요.

아마 CSV 링크도 구현할 것 같아요. :wink:

걱정 마세요 :wink: . 천천히 하세요, 저는 급하지 않거든요

좋아요! 저장소에 새 버전이 올라왔습니다. i18n 지원뿐만 아니라, 누군가 RSVP를 취소했을 때 업데이트가 게시되지 않던 버그도 찾아서 수정했습니다.

문제가 있으면 알려주세요!

안녕하세요. 이벤트에 참여하거나 참여하지 않는 사용자와 관련하여 문제가 있었습니다. 이벤트에 두 개의 아바타가 하나만 표시되어야 할 때 두 개가 표시되었고, 새로고침을 하면 해결되었지만 사용자에게 혼란을 주었습니다. 제 쪽에서 코드를 수정했는데, 이것이 도움이 될지 모르겠습니다.

훌륭한 아이디어입니다. UI 혼란을 초래할 수 있는 이유를 잘 이해할 수 있습니다. 레이스 컨디션(race condition)을 방지하기 위해 Mutex를 추가하고 플러그인의 새 버전을 배포했습니다.

생각하시는 점이 있으시면 알려주세요!

2026.9.0-latest 버전 이후로 이벤트 등록 알림을 더 이상 받지 못하고 있습니다. 이 문제가 저 혼자만 겪고 있는지 모르겠습니다.

디스코urs 캘린더가 이벤트로 대체되었기 때문에 이 문제가 발생하는 이유를 파악할 수 있을 것 같습니다.

저희 쪽에서 plugin.rb 파일을 수정하여 새로운 버전의 discourse와 호환되도록 했습니다.
