Alembic hook that allows enums values to be upgraded and downgraded in migrations automatically
This package implements an Alembic hook that causes alembic revision --autogenerate to output PostgreSQL ALTER TYPE .. ADD VALUE SQL
statements as part of new migrations.
Add the line:
import alembic_autogenerate_enums
To the top of your env.py.
Since ALTER TYPE .. ADD VALUE cannot run transactionally, each
op.sync_enum_values() call creates its own temporary private DB connection.
See https://bitbucket.org/zzzeek/alembic/issues/123/a-way-to-run-non-transactional-ddl
We have incredibly basic tests in a sample project.
mkvirtualenv alembic-autogenerate
Install the main autogenerate package and then the test harness:
pip install -e .
pip install -e test-harness
createuser alembic-autogenerate
createdb -O alembic-autogenerate alembic-autogenerate_db
cd test-harness && pytest
