The intention of this library is to make it easy to inherit particular variables between models in rails apps. We start with a parent model that will function as a pseudo-polymorphic association for children objects.

Automatically sets up usage of a relational table to contain user-created multi-locale string attributes

Easily associate locations with your models.

Logging your ActiveRecord model, and supply useful methods.

This plugin implements Flickr's machine tags as explained here[http://www.flickr.com/groups/api/discuss/72157594497877875] while still maintaining standard tagging behavior. Basically, a machine tag has a namespace, a predicate and a value in the format [namespace]:[predicate]=[value] This allows for more precise tagging as tags can have unlimited contexts provided by combinations of namespaces and predicates. These unlimited contexts also make machine tags ripe for modeling relationships between objects. Read the HasMachineTags::TagMethods class documentation for a more thorough explanation. A demo app using this plugin is here. This gem should run on all major Ruby versions and work with Rails 2.3.x and up.

Add multiply emails features to models like User without changing common behaviour of the email attribute

An ActiveRecord plugin for self-referential and double-sided polymorphic associations.

An ActiveRecord plugin that combines an ordered habtm-like association with optional redis caching.

A key/value store solution for Rails apps with bloated tables

Create one model backed by a primary table and a supplementary 'meta' table.

Calculate metrics and store them in the DB.

Parsing the various ways people enter dollar amounts so you don't have to. Store values in cents as integer.

Use the Money gem and ActiveRecord's composed_of to store fields wich contains currency data in a safe and clean way.

Time-safe finders for ActiveRecord's has_secure_token.

has_normalized_fields is a Ruby on Rails gem that lets you normalize user data for an improved user experience. It takes the messy user inputed data and normalizes it into a nice clean standard format.

has_normalzied_sti is a rails extension to allow Single Table Inheritance to work with a database normalized type column. The extension expects the STI model to have a type_id column instead of a type column. type_id should reference a Types table containg all the possible types. The types table will be auto populated with new types as new subclasses are saved.

Ordering behavior for ActiveRecord models and Mongoid documents.

Generate random tokens (or use your own) for any ActiveRecord model. Hashes and salts the token before storage in the database using the same methodology as has_secure_password.
