RandomFinders

=======

Allows quick and easy fetching of random records, or records in random order.

Simply pass the :random to the order in any finder method.

Examples

==

Find a random article

  Article.find(:first, :order => :random)

Randomize photos

  Photo.find(:all, :order => :random)

Caveat

This will not treat you nicely with large datasets.
