Changelog

Sourced from activerecord's changelog.

Rails 8.1.1 (October 28, 2025)

• No changes.

Rails 8.1.0 (October 22, 2025)

• Fix SQLite3 data loss during table alterations with CASCADE foreign keys.

  When altering a table in SQLite3 that is referenced by child tables with ON DELETE CASCADE foreign keys, ActiveRecord would silently delete all data from the child tables. This occurred because SQLite requires table recreation for schema changes, and during this process the original table is temporarily dropped, triggering CASCADE deletes on child tables.

  The root cause was incorrect ordering of operations. The original code wrapped disable_referential_integrity inside a transaction, but PRAGMA foreign_keys cannot be modified inside a transaction in SQLite - attempting to do so simply has no effect. This meant foreign keys remained enabled during table recreation, causing CASCADE deletes to fire.

  The fix reverses the order to follow the official SQLite 12-step ALTER TABLE procedure: disable_referential_integrity now wraps the transaction instead of being wrapped by it. This ensures foreign keys are properly disabled before the transaction starts and re-enabled after it commits, preventing CASCADE deletes while maintaining data integrity through atomic transactions.

• Add replicas to test database parallelization setup.

  Setup and configuration of databases for parallel testing now includes replicas.

  This fixes an issue when using a replica database, database selector middleware, and non-transactional tests, where integration tests running in parallel would select the base test database, i.e. db_test, instead of the numbered parallel worker database, i.e. db_test_{n}.

• Support virtual (not persisted) generated columns on PostgreSQL 18+

  PostgreSQL 18 introduces virtual (not persisted) generated columns, which are now the default unless the stored: true option is explicitly specified on PostgreSQL 18+.

  create_table :users do |t|
    t.string :name
    t.virtual :lower_name,  type: :string,  as: "LOWER(name)", stored: false
    t.virtual :name_length, type: :integer, as: "LENGTH(name)"
