정말 잘못 여기에 갈 수 있습니다 모르겠어요 :

alembic -c development.ini revision --autogenerate -m "test"

나는 다음과 같은 결과를 얻을. Postgres 9.2, SQLAlchemy 0.8.4 및 Alembic 0.6.1을 사용하고 있습니다. Postgres 9.3, SQLAlchemy 0.9, Alembic 0.6.2에서도 같은 결과를 보았습니다. 우리는 차이를 만드는 경우 사용자 지정 데이터베이스 스키마를 사용하고 있습니다.

다른 스키마에 같은 이름의 두 개의 테이블이 있고 "기본"스키마에있는 하나의 인덱스에 인덱스가있는 경우이 추적을 볼 수 있습니다. 기본값이 아닌 기본값은 아래에 언급 된 pullreq가이를 수정합니다. . – zzzeek

이 문제는 최신 git 마스터에서 수정되었으며 0.6.3에서 릴리스 될 예정입니다. – zzzeek

이 버그는 맞춤 스키마와 alembic을 사용할 때 나에게도 발생했습니다. This commit이 수정되었습니다.
