== DESCRIPTION:

Live validator is a Rails Guilded (http://github.com/midas/guilded/tree/master) component that will reflect ActiveRecord validations and use them to live validate forms. Live validator uses the Live Validation (http://www.livevalidation.com) JavaScript library to accomplish this task. It also uses an ActiveRecord extension authored by Michael Schuerig to mre easily reflect on the ActiveRecord valdiations.

== FEATURES:

• Validate Rails XHTML forms without submitting form to server.
• Declare validations once in ActiveRecord model's. If JavaScript is enabled, the validation will happen live. Otherwise, the validation will happen normally, with a submission to the server.
• The error message defined in the validation macro will be used in live validation
• The following ActiveRecord validations are currently implemented and working: validates_presence_of (:message), validates_numericality_of (:less_than, :less_than_or_equal_to, :equal_to, :greater_than, :greater_then_or_equal_to, :only_integer, :notANumberMessage, :notAnIntegerMessage, :wrongNumberMessage, :tooLowMessage, :tooHighMessage), validates_length_of / validates_size_of (:maximum, :minimum, :is, :within, :in, :too_long, :too_short, :wrong_length), validates_confirmation_of (Only works for 2 fields, no more nor less.), validates_acceptance_of (:message), validates_inclusion_of (:message), validates_exclusion_of (:message)

==PROBLEMS:

== INSTALL:

sudo gem install midas-g_live_validator

Add gem requirement to your environment.rb file:

config.gem 'midas-g_live_validator', :version => '1.0.4', :lib => 'g_live_validator', :source => 'http://gems.github.com'

Generate:

script/generate live_validator_assets

== USE:

Make a call to the view_helper within a form:

<%= g_live_validator f %> # where f is the form variable passed into the form_for block

To use with a library like midas-dynamic_Validations, that does not use ActiveRecord validations, but some other method of defining validations:

<%= g_live_dynamic_validator f, @validation_definitions %>

== OPTIONS:

:except - List of fields not to validate. Foreign key fields (that end in _id) are automatically excluded. Can be a string, symbol or an array of string or sybmols.
