A helper that finds the informed word(when running in shell), and gives all the options, with the respectives I18n keys, like "activerecord.models.attributes.etc.name"

map.each do |key, value|
if value.is_a? Hash
find("#{path}#{key}.", value)

Created September 14, 2011 19:40
A stupid script that may be used a single time to migrate an old data-base to one of those new rails multi-tenancy(scoped) apps. It's not pretty. Not even safe, so watchout =P
%x[ls -R app/models/].split("\n").each do |w|
begin
w[0...-3].camelize.constantize.unscoped.each{ |u| u.update_attribute(:company_id, Company.unscoped.first.id) }
