Sqlalchemy sqlite problems bd

При миграции с [alembic] выпадает ошибка “No support for ALTER of constraints in SQLite dialect”

В env.py алембика проставить:

context.configure(
    connection=connection,
    target_metadata=target_metadata,
    render_as_batch=True # <===this
)

Не помогло создать миграцию - надо ковырять ,ini. Вариант решения - прописывать руками. Статья.
