Map persisted data to and from POROs

Simple Polymorphic Behavior with Enum Related Object and Delegation.

Enumerate adds an `enumerate` command to all ActiveRecord models, enabling you to work with string or integer columns as if they were enums. The following features are added to your model: Validation - ensures that the field only receives accepted values Predicate Methods - adds ? and ! functions for each enum value Scopes - you can easily query for values of the enum

EnumeratedField is a library that provides some nice methods when a string column is used like an enumeration, meaning there is a list of allowable values for the string column.

Eliminates "Undeclared attribute type for enum" errors that occur when running migrations with multiple enum columns added in separate migrations. Automatically declares missing enum attributes as integers, preventing migration failures.

EnumExporter is rake task that exports defined enums as some formats.

Enum extension introduces: enum supersets, enum mass-assign, easy localization, and more sweetness to Active Record enums.

Scopeless enums, and some syntactic sugar for string enums

ActiveRecord::Enum fire SQL request and bypass ActiveModel::Validations, this let you play with enum and validation

Add `from_file` option to Rails enum.

Create Enum-like values directly in the database for flexibility, power and supremacy.

This gem allows to create enum records (named records) and to retrieve them easily. Supports globalize3 localization in enum fields initialization.

A form helper for the enum field of Rails model.

Allows using a single integer column as a set of booleans, with bitfield-style storage.

Changes the return value of enums to symbols.

Active Record ENUM based state machine, whether you can restrict status transition from one to other

Add state maps to Rails Enums for validation on transitions.

Envdocs allows you to find missing env keys, as well as create living documentation of the keys themselves.

Asset libraries for web and scaffold templates in modern style (uses "simple_form", "haml", "cancan").

Ephemeron improves the performance of your app. It takes on itself the persistence of the ActiveRecord objects. It protects you from saving the same object many times. It checks whether a fetched from a database object was used. It allows you to eliminate the controller's before_actions that are unnecessarily called. Ephemeron works in the context of the thread and does the bulk of its job (i.a. persistence) at the end of the thread's lifecycle. Although, you can trigger the finalization at any given moment. You don't have to make a distinction in the code for the part that is responsible for the domain logic and the other responsible for the application layers.
