Schema source#

colref looks for a schema source in the following order:

1. db/schema.rb — the standard Rails schema dump (:ruby format). Present in most projects.
2. db/structure.sql — used when config.active_record.schema_format = :sql (PostgreSQL-specific features such as custom types, partial indexes, or materialized views that schema.rb cannot represent). Supports PostgreSQL, MySQL, and SQLite quoting styles.
3. db/migrate/ — fallback when no schema dump is committed. colref replays migration files in timestamp order — create_table, add_column, remove_column, rename_column, drop_table — to reconstruct the current schema.

Model and field validation are fully intact regardless of which source is used.
