DB migrations and schema changes

To generate and apply Alembic migrations, you first set up the environment, configure the database URI, autogenerate the revision for your ORM schema change, and then apply the migration using the standard workflow. This process ensures reliable, repeatable database migrations across your environments.

The best way to debug migration issues between SQLite and Postgres is to follow a standardized workflow that guides you through environment preparation and repository conventions. This approach helps resolve inconsistencies and ensures schema changes are applied correctly across different database environments.

Yes, you need to configure the database URI before autogenerating Alembic revisions. Proper environment preparation and URI configuration are enforced steps in the workflow, ensuring that the schema changes are correctly mapped and applied to your specific SQLite or Postgres database setup.

Yes, you can use this approach to add ORM columns across different database environments. The workflow is designed to manage Alembic database migrations and schema changes, simplifying complex migrations and ensuring consistency across SQLite, Postgres, and related environments.

Your database schema change might break when switching between SQLite and Postgres due to environment inconsistencies. By enforcing environment preparation, URI configuration, and clear repository conventions, you can debug and resolve these migration issues to maintain reliable database migrations.
