Zammad: input, select, tree_select, richtext, textarea, 확인란 유형의 속성에 기본값이 설정되지 않았습니다.

테스트 인스턴스에서 개발을 테스트 할 때이 버그에 대한이 수정과 관련된 오류가 발생했습니다.

이것이 버그인지 아니면 개발중인 WIP 실행의 아티팩트인지 확실하지 않지만 만일을 대비하여 여기서 공유합니다 ..

안녕하세요 @abeluck- 피드백에 감사드립니다. 이것은 우리에게 매우 귀중합니다! 후속 수정은 현재 품질 보증을 거치고 있습니다.

안녕하세요 @abeluck- 더 긴 토론 후에 우리는 그것이 도입 할 부작용 때문에 변경 사항을 되돌려 야했습니다 (특히 더 큰 시스템에서).

문제는 속성의 기본값을 변경하거나 도입하면 대형 시스템에서 상당히 많은 시간이 소요되는 alter table로 이어진다는 것입니다. 따라서 애플리케이션 기반 기본값 (ActiveRecord 콜백을 통해)이 데이터베이스 기반보다 선호됩니다.

어쨌든 지금부터 약 30 분 후에 develop 에서 테스트 시스템을 업데이트 할 수 있습니다.
