validates_with_block

= ValidatesWithBlock

A plugin that allows for dynamic, more readable block-driven validation for ActiveRecord models.

== Installing as a plugin

EDGE Rails has support for plugin installation from Git, so if you're using EDGE Rails you can install with:

./script/plugin install git://github.com/fhwang/validates_with_block.git

We're maintaining an SVN clone of the plugin for those of you who aren't on EDGE Rails yet:

./script/plugin install svn://rubyforge.org/var/svn/nycrb/validates_with_block

== Using ValidatesWithBlock

Basically this plugin is meant to help you make your models a little cleaner if you've got a lot of validations. Instead of:

validates_presence_of :login, :message => 'Please enter a login.' validates_uniqueness_of :login, :case_sensitive => false validates_format_of :login, :with => /\A\w*\Z/ validates_length_of :login, :within => 4..15

You can write:

validates_login do |login| login.present :message => 'Please enter a login.' login.unique :case_sensitive => false login.formatted :with => /\A\w*\Z/ login.length :within => 4..15 end

The methods map to validation methods as follows:

login.confirmed => validates_confirmation_of login.formatted => validates_format_of login.formatted_as_email => validates_email_format_of login.length => validates_length_of login.present => validates_presence_of login.unique => validates_uniqueness_of

== formatted_as_email

You may have noticed the inclusion of validates_email_format_of; that's not a standard ActiveRecord validation. It comes from the very useful validates_email_format_of plugin, which is available at http://code.dunae.ca/validates_email_format_of.html . Obviously formatted_as_email won't work if you haven't installed this plugin.
