If you dont want to get into memcache or other complex solutions you
can do something simple like this:
class StylesCache
include Singleton
def self.by_name(name)
self.instance.by_name(name)
end
def by_name(name)
return @active_style if @active_style && @active_style.name ==
name
@active_style = Style.find_by_name(name)
return @active_style
end
end
style = StylesCache.by_name("newsletter")
