## What it is
ranked-model is a Ruby gem for Rails that manages row ordering/sorting in ActiveRecord models, serving as a modern replacement for acts_as_list and acts_as_sortable. It uses relative integer ranking with ARel for efficient positioning of records within scoped lists.

## Use cases
- sort rails records with drag and drop ordering
- maintain ordered lists in activerecord models
- replace acts_as_list with better performance
- reorder rows in a scoped list without rewriting all positions
- implement sortable todo or playlist items in rails

## When to choose
- you need efficient reordering of large lists without updating every row
- you want relative positioning with scoped ordering in Rails 4.2+

## When to avoid
- you are starting a new project - the maintainer recommends the newer Positioning gem
- you are not using Rails or ActiveRecord

## Facets
- artifact type: library
- maturity: maintenance
- function: orm, database
- domain: web-development, backend, databases
- platform: ruby
