any_of.rb

class ActiveRecord::Base
  def self.any_of( *queries )
    queries = queries.map do |query|
      query = where( query ) if [ String, Hash ].any? { |type| query.kind_of? type }
      query = where( *query ) if query.kind_of?( Array )
      query.arel.constraints.reduce( :and )
    end

    where( queries.reduce( :or ) )
  end
end

Definitely love that, thanks

This is awesome. It confused me a bit because I tried to pass in an array of hashes like this: [{name:'Joe',age:42},{name:'Frank',age:32}] you have to splat (*) your arguments to get it to work w/ the way it's written. I'm going to fork it and rewrite it w/o the splat in the argument list so you can pass in an array.
