Can Alembic Autogenerate column alterations?

Looks like I found the answer on reddit’s /r/flask.

Just add “compare_type=True” to context.configure() parameters inside your env.py’s “run_migrations_online” function.

    context.configure(
                connection=connection,
                target_metadata=target_metadata,
                compare_type=True
                )
