I've been frustrated by the lack of humanity in Rails so-called human names. So I wrote a little library, which was largely stolen from Change displayed column name in Rails validation messages. The library lets you do something a little like this...

require 'human_attributes'

class Puppy < ActiveRecord::Base
  humanize_attributes :breakfast => "Puppy's preferred breakfast"
  validates_presence_of :breakfast
end

It doesn't do anything very spectacular, but it took me a long time to work out.

# lib/human_attributes.rb

module ActiveRecord
  class Base
    # Humanize attributes
    def self.human_attribute_name(attr)
      @humanized_attributes ||= {}
      @humanized_attributes[attr.to_sym] || attr.humanize
    end

    def self.humanize_attributes(*args)
      @humanized_attributes = *args
    end
  end
end

ActiveRecord::Base#humanattributename is deprecated and will be replaced by proper string inflection. For those with fancy, modern humanizing Inflectors you might have to change it to something like this.

def self.humanize_attributes(*args)
  humanized_attributes = *args
  Inflector.inflections do |inflect|
    humanized_attributes.each do |attr, label|
      inflect.human attr.to_s, label
    end
  end
end

Although I couldn't get that to work, probably because my Rails isn't new enough.
