[dependabot]

Bumps activerecord from 8.1.1 to 8.1.2.

Release notes

Sourced from activerecord's releases.

8.1.2

Active Support

• Make delegate and delegate_missing_to work in BasicObject subclasses.

  Rafael Mendonça França

• Fix Inflectors when using a locale that fallbacks to :en.

  Said Kaldybaev

• Fix ActiveSupport::TimeWithZone#as_json to consistently return UTF-8 strings.

  Previously the returned string would sometime be encoded in US-ASCII, which in some cases may be problematic.

  Now the method consistently always return UTF-8 strings.

  Jean Boussier

• Fix TimeWithZone#xmlschema when wrapping a DateTime instance in local time.

  Previously it would return an invalid time.

  Dmytro Rymar

• Implement LocalCache strategy on ActiveSupport::Cache::MemoryStore. The memory store needs to respond to the same interface as other cache stores (e.g. ActiveSupport::NullStore).

  Mikey Gough

• Fix ActiveSupport::Inflector.humanize with international characters.

  ActiveSupport::Inflector.humanize("áÉÍÓÚ")  # => "Áéíóú"
  ActiveSupport::Inflector.humanize("аБВГДЕ") # => "Абвгде"

  Jose Luis Duran

Changelog

Sourced from activerecord's changelog.

Rails 8.1.2 (January 08, 2026)

• Fix counting cached queries in ActiveRecord::RuntimeRegistry.

  fatkodima

• Fix merging relations with arel equality predicates with null relations.

  fatkodima

• Fix SQLite3 schema dump for non-autoincrement integer primary keys.

  Previously, schema.rb should incorrectly restore that table with an auto incrementing primary key.

  Chris Hasiński

• Fix PostgreSQL schema_search_path not being reapplied after reset! or reconnect!.

  The schema_search_path configured in database.yml is now correctly reapplied instead of falling back to PostgreSQL defaults.

  Tobias Egli

• Restore the ability of enum to be foats.

  enum :rating, { low: 0.0, medium: 0.5, high: 1.0 },

  In Rails 8.1.0, enum values are eagerly validated, and floats weren't expected.

  Said Kaldybaev

• Ensure batched preloaded associations accounts for klass when grouping to avoid issues with STI.

  zzak, Stjepan Hadjic

• Fix ActiveRecord::SoleRecordExceeded#record to return the relation.

  This was the case until Rails 7.2, but starting from 8.0 it started mistakenly returning the model class.

  Jean Boussier

• Improve PostgreSQLAdapter resilience to Timeout.timeout.

  Better handle asynchronous exceptions being thrown inside the reconnect! method.
