Overview

This class is abstract.

Subclass this validator to perform your specific validations.

An EachValidator that uses the translation table to build its error messages. Override the #valid? method to describe your validation conditions of your subclasses.

The error message translation lookups conform to the standard hierarchy of internationalization keys as described by the ActiveRecord::Errors#generate_message method. (See its documentation for more information.) The last portion of the translation key path is the error message key, and by default it is the name of the validator class (excepting "Validator"), underscored and demodulized. For example, an EmailAddressValidator subclass would use the email_address key within the normal ActiveRecord error key structure.
