automatically strip values of activerecord attributes

This should do the trick:

class User < ActiveRecord::Base

   def self.auto_strip(*args)
     args.each do |attribute_to_strip|
       class_eval <<-RUBY
         def #{attribute_to_strip.to_s}=(value)
           write_attribute :#{attribute_to_strip.to_s}, value.strip
         end
       RUBY
     end
   end

   auto_strip :name, :street
end
