Schema workflow

The schema/*.dbml files are the database schema source of truth.

Generate SQL migrations

Run:

make generate-migrations

This uses relspec to convert the DBML files into PostgreSQL SQL and writes the generated schema migration to:

• migrations/020_generated_schema.sql

Generate ResolveSpec models

Run:

make generate-models

This uses relspec to convert schema/*.dbml into Bun/ResolveSpec-compatible Go models in:

• internal/generatedmodels/

Check schema drift

Run:

make check-schema-drift

This regenerates the SQL from schema/*.dbml and compares it with migrations/020_generated_schema.sql. If the generated output differs, the command fails so CI can catch schema drift.

Workflow

1. Update the DBML files in schema/
2. Run make generate-migrations
3. Run make generate-models
4. Review generated SQL and generated models
5. Commit DBML changes and generated outputs

Existing handwritten migrations stay in place. Going forward, update the DBML first and regenerate the SQL from there.
