이벤트 이름에 따옴표가 있으면 참석자가 삭제됩니다

[dsims (Daniel)]

Discourse Events 이벤트 이름에 이벤트 이름: 참가 "참석"으로 참여와 같이 따옴표를 넣으면

저장 시 PUT /posts/123에 500 오류가 발생하며(아마도 깨진 마크다운 때문일 것입니다) 문제는 이벤트의 모든 참석자가 지워지는 것처럼 보인다는 점입니다.

참고: 이 문제는 https://meta.discourse.org/t/discourse-livestream/341335와 함께 사용되었지만, 관련이 없다고 생각합니다.

Yikes, we will have a look at this some time in the coming week.

Given you are getting a 500, can you look in /logs and let us know what you see there?

I think what is happening is the unescaped quotes break the event markup, so no event is detected and the event is destroyed. Then when I remove the quotes and hit save again, a new event is created.

The 500 error during serialization is probably a related side-effect.

Thanks for the report @dsims, this will be fixed once this PR gets merged.

It’s not the “best” fix, but at least the event won’t break if a user enters a " in one of the event modal’s fields.
