AR.find(..).each

Working with ActiveRecord it often bothers me I need to write each after doing a find-all. I can give find a block but is just ignored without any warning.

So today no new method but the removal of a method!

class ActiveRecord::Base
  def self.find_with_block_sensitivity(*args)
    r = find_without_block_sensitivity(*args)
    [r].flatten.each {|v| yield v} if block_given?
    r
  end

  class << self
    alias_method :find_without_block_sensitivity, :find
    alias_method :find, :find_with_block_sensitivity
  end
end

Now, instead of:

Article.find(:all).each {|article| puts article.title}

we can write:

Article.find(:all) {|article| puts article.title}

Look ma! No each! Also works for single object results.
