Cannot complete Flask-Migration

Question

I\'ve setup a local Postgres DB with SQLAlchemy and cannot commit my first entry. I keep on getting this error...

ProgrammingError: (ProgrammingError) relation          


        

Answer 1

I had the same issue. According to the version in alembic_version table in db, migration action is looking for that version in /migrations/versions folder which has already been deleted. Therefore solution is to delete alembic_version table: If you are using sqlite, 1. Open your xxx.sqlite db file. sqlite3 xxx.sqlite 2. check tables .tables 3. you will see alembic_version, delete it DROP TABLE alembic_version
