Given below is a model from mephisto blogging tool.
class Tag < ActiveRecord::Base
@@tag_parse_regex = /((?:
|)[''"]{0,1})[''"]?\s*(.*?)\s*(?:[,''"]|$)(?:\1(?:
|$))/
has_many :taggings
class << self
def [](tag)
find_by_name(tag.to_s)
end
.................
..................
How to consume the above method and why it in this confusing way. Why the
name of the method is [] ...seems like an index to me. Am I supposed to
consume this method Tag.[1] ?
Thanks.

You do not need a "." to call it, like other methods: Tag[:something] Duane Johnson (canadaduane) http://blog.inquirylabs.com/ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
