= active-form plugin for Rails

active-form is a plugin that makes it easy to have model objects that support the ActiveRecord Validations but are not backed by database tables. The plugin is designed to make it possible to use the ActiveForm derived classes in a very similar manner to the ActiveRecord::Base derived objects.

== How To Define An ActiveForm Object

class Search < ActiveForm attr_accessor :text validates_length_of :text, :maximum=>30 end

== How To Use ActiveForm Object In Controller

class NavigatorController < ApplicationController def search @search = Search.new(params[:search]) if @search.valid? ...do search here... end end end

== How To Use ActiveForm Object In View

<%= start_form_tag(:action => 'search') %> <%= error_messages_for('search') %> <%= text_field('search', 'text', {"maxlength" => 30}) %> Save <%= end_form_tag %>
