v0.2.0

Major Changes

This version introduces advisory locks. Advisory locking is automatically enabled if your model class responds to #with_advisory_lock (ex. User.with_advisory_lock).

From now on the lexorank gem requires ruby version 3.1 or higher. This decision is based on ruby's end of life dates (3.0 went eol in April 2024).

All internal API methods that lexorank was using until 0.1.3 were moved to another location. If you rely on those (and you should not), have a look at the Lexorank::Ranking class. An instance of this class can be accessed via the lexorank_ranking attribute on your model class.

Added

• Add advisory locks if the model class responds to with_advisory_lock
• Add #move_to_end and #move_to_end! to move a record to the end of a collection
• The CI now runs against multiple database adapters (sqlite, mysql, postgresql)

Changed

• Blocks passed to all move_to methods will now be executed after the rank was assigned. When using advisory locks, the block will be executed while the lock is still active.
• When calling #move_to with a position that is larger than the number of records in the collection it will now be moved to the end of the list
• Require ruby version 3.1 or higher
• Moved Changelog from README.md to CHANGELOG.md
