Allows step change for attributes.

Add default attribute values when creating models.

Simple and fast module for named arguments in model initializers

A String class, but with attributes marking data at specific ranges.

Attribute Extenstions

Concise way of filtering model attributes in Rails.

Provides auto-serialization of simple Ruby types that databases do not support, such as symbols and classes.

Provides shortcut for transforming attributes into a StringInquirer

A matcher for testing object attributes.

Specific normalizers that we commonly use in our apps

Easily generate form fields and object information fields with labels.

Makes querying encrypted & salted attributes mildly less horrible

Ruby gem for adding width and height attributes to image tags within HTML blocks

Declarative attributes mapping

Sort a collection of objects using one or more of the attributes of your object.

Attribute Stats gives you insight into which attributes are actually used in your Rails models. Whether you're joining an existing project or have been using it for years, get quick info. The stats help you find smells in your project: Attributes which have never had data set (indicates a potentially forgotten attribute); Tables which haven't been updated for X years (indicates a potentially unused or legacy model); Attributes used by very few objects in your table (is this being used? Should it be an attribute?) It also generates sample Rails database migration code to allow you to drop the database columns.

A flowdown wrapper for attribute dependencies

AttrImmutable add the attr_immutable class method to create immutable properties on Ruby classes. The attribute are only accessible using the accessor/mutator pair by hiding the attribute value using a closure. (ie. the immutable attribute is not stored in an instance variable and therefore can't be accessed in any other way. No developer end runs.)

Reader structs for ruby finally!.

attr_inject is a simple dependency injection solution for ruby.
