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.

Add ability to draft/publish/withdraw/embargo models

Extremely simple API support for Rails models

Does what `has_secure_password` does, but for any attribute that you want. It does not have to be a `password` attribute. It may be for example `security_answer`

Drop-in replacement for has_secure_password that uses argon2

HasSecureUuid provides you an easily way to generate random uuids for any model in ruby on rails. **SecureRandom::uuid** is used to generate a unique uuid, so collisions are highly unlikely.

Allows to easily add SEO fields for models

Adds dynamic attributes through serialize. This way, it's in one table, and it's still trivial to track changes to your records.

parent.children.where.not(id: self.id), extended to n parents

has_sti provides helper methods for Single Table Inheritance models of Active Record. It creates methods that allow to determine exact type of model and scopes that make easy to find records of certain type.

Simple tagging with contexts.

Identifies your active records with a random token. For more information, please see the documentation.

Extend ActiveRecord models to generate uniq secure tokens before saving

Identifies your active records with a random token. For more information, please see the documentation.

For those pesky times when has_many just isn't specific enough.
