Extraction of the ActiveRecord::Base#import functionality from ar-extensions for Rails 3 and beyond

ROXML is a Ruby library designed to make it easier for Ruby developers to work with XML. Using simple annotations, it enables Ruby classes to be mapped to XML. ROXML takes care of the marshalling and unmarshalling of mapped attributes so that developers can focus on building first-class Ruby classes. As a result, ROXML simplifies the development of RESTful applications, Web Services, and XML-RPC.

Lightweight gem that utilizes Rails server-side model validations to display client-side error messages for Ajax form submissions.

DSL for encryption and decryption of attributes in ActiveRecord models

Encrypt attributes using AES-256-CBC (or your custom encryption strategy). Works with and without ActiveRecord.

This gem provides a dead-simple encryption of string / text attributes of ActiveRecord and Mongoid models. Encryptor internally uses ActiveSupport::MessageEncryptor and therefore it uses 'aes-256-cbc' cipher by default. Gem does NOT require column with different name. From user perspective encryption is completely transparent - they use decrypted values all the time, but encrypted values are stored in database.

Easily encrypt columns in your app conditionally and with hashed values for searching

Encrypting a field makes it very difficult to perform a case insensitive search for the columns data. This gem normalizes the text before encrypted it and storing it in a search column. The current normalization method is to convert the text to all lowercase.

A macro-style method that will automatically read the database contraints (null requirements, string length, etc) and enforce those at the model level to keep validation more DRY. Provides many options to customize how automatic it is and what columns it affects.

Allows for natural grammar to specify object relationships based on parts of speech.

Enkrip will encrypt & decrypt Active Record attributes seamlessly with Message Encryptor. By default compatible with Active model validation
