= NotNaughty - The Validation Framework

NotNaughty extends your ruby Project with a highly custumizable validation API.

== Features

Easy to adapt:

require 'rubygems' require 'not_naughty'

Person = Struct.new(:name) do extend NotNaughty validates(:name) { presence and length :minimum => 4 } end

Person.new('Horst').valid? # => true Person.new('Foo').valid? # => false

Easy to extent:

class ExampleValidation < NotNaughty::Validation def initialize(options, attributes) msg = options[:message] || '#{"%s".humanize} is not an example.'

   super options, attributes do |record, attribute, value|
     record.errors.add(attribute, msg) unless value.is_a? Example
   end
 end

end

Person.instance_eval do validates_example_of :example_attribute end

Handle SQL error gracefully:

Person.instance_eval do validator.error_handler.handle(SQLError) { |err| '...' } end

Syntactical Sugar with Builder methods:

validates(:username, :password, :if => :new?) {length :minimum => 6} validates(:password, :allow_blank => 1) {confirmation and complexity :high}

Beautiful error messages:

validates_presence_of :red_shoes, :message => '#{"%s".humanize} are not here.' # => Red shoes are not here.

Conditional Validations:

validates(:if => :necessary?) {...} validates(:unless => proc {|obj| obj.vip?}) { '...' }
