ActiveModel::Filters

Overview

Provide a ActiveModel::Validations style set of helpers for models to add input filters that work on all dirty fields before validation.

The point of this is I have a project that requires some data consistency and right now that's all ad-hoc and messy. I need a better way to quickly ensure that a username is lower case, things are trimmed properly before stored in the db, etc. Right now that's all done manually on the controller or model, or not at all.

Example Usage

Ruby:

def factorial(n)
  return 1 if n.zero?
  1.upto(n).inject(:*)
end

PHP:

	class User < ActiveRecord::Base;end

	klass = 'User'

	Kernel.const_get(klass)
	# => User(id: integer)

	if Rails.env.development? \|\| Rails.env.test?
	...

	ENV['SKIP_RAILS_ADMIN_INITIALIZER'] = 'true'

	...
	end

	// Ruby:

	def multiply_by_two(i)
	i * 2
	end

	// PHP:

	public function multiply_by_two($i) {
	return $i * 2;

	process = fork do
	File.open('./output.txt', 'w') do \|f\|
	20.times do \|i\|
	f.write "Tick #{i}\n"
	f.flush
	sleep 1
	end
	end
	end

	# Fun fact...

	redirect_to some_path, notice: 'My notice'

	redirect_to some_path, error: 'My error message'

	# first will set a flash[:notice] while second will NOT set a flash[:error]

	# vs:
	flash[:notice] = 'My notice'

	(function($){
	$.entwine('ss', function($) {
	$('.ss-gridfield .action.userform-export-csv').entwine({
	onclick: function(e){
	var self = this, btn = this.closest(':button'), grid = this.getGridField();

	var data = '';

	// Add current button
	data += '&' + encodeURIComponent(btn.attr('name')) + '=' + encodeURIComponent(btn.val());
