Don’t forget to provide tests for any modifications you make to the model (most likely, you will need to add them to the appropriate test/unit/data/model/mapping/test_*model_mapping.py module.Īfter that, run the upgrade script. We encourage you to use Galaxy-specific utility functions ( galaxy/model/migrations/util.py) when appropriate. You’ll need to fill out the upgrade and downgradeįunctions. Migrations/alembic/versions_tsi for tsi). Script in the appropriate version directory ( migrations/alembic/versions_gxy for gxy and Run_alembic.sh script (see sections above for usage information).
You create a new revision file by running the revision subcommand of the manage_db.sh or the Make sure you have updated the model and have added appropriate tests before creating a new In most cases, you’ll need to upgrade the database schema to the current version, which is represented by the latest revision script in the migration environment.ĭeveloping Galaxy: creating new revisions ¶ If they do not match, and the database_auto_migrate configuration option is not set, Galaxy will fail with an error message explaining how to proceed. On startup, the system checks if the version in the database matches the version in the codebase. For Galaxy to run, these versions must be the same, which, essentially, means that the version of the database matches the version expected by the codebase. Galaxy keeps track of the database schema version in two places: one is a directory we refer to as “the migration environment” (located at lib/galaxy/model/migrations/alembic), the other is the alembic_version table in the database. Executing a revision script will upgrade, or downgrade, the database schema by applying the changes specified in the script. A version is represented by a revision script (the terms version and revision may be used interchangeably). Central to this is the concept of a database version (more specifically, database schema version). The purpose of the database schema migration system is to support automated, incremental, reversible changes to Galaxy’s database schema.
