Rails - Dec 2007 - automatically strip values of activerecord attributes

i am doing a couple of times the following in my models

class User < ActiveRecord::Base
  def name=(val)
    write_attribute :name, val.to_s.strip
  end
end

quite clear, it strips the name when setting it.
now the question: Is it possible to do something like the following ..
and if yes how could i achieve it

class User < ActiveRecord::Base
  auto_strip :name, :street
end

thanks...

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
