Ruby/RoR: calling original method via super()?

Question

In a RoR app, I want to specialize ActiveRecord\'s update_attributes() method in one of my models, extracting some of the attributes for special handling and passing the res

Answer 1

This looks like a better use for alias_method_chain:

def update_attributes_with_special(attrs)
  attrs.each_pair do |key, val|
    unless has_attribute?(key)
      do_special_processing(key, val)
      attrs.delete(key)
    end
  end
  update_attributes_without_special(attrs)
end
alias_method_chain :update_attributes, :special
