# This is a representation of a page of the wiki. My wiki is awfully simple
|
||
|
|
# because i don't like too many features. This works and it has many different
|
||
|
|
# associations. All of the major models has_one of these and it belongs_to
|
||
|
|
# some kind of polymorphic owner.
|
||
|
|
#
|
||
|
|
# Bonuses:
|
||
|
|
# * Uses RedCloth markup.
|
||
|
|
# * Automatically converts/caches HTML
|
||
|
|
# * Allows any character or space in the name
|
||
|
|
# * Uses [[ and ]] for WikiWord representation.
