Are there any downsides to doing something like this assuming Foo data
rarely changes?
class Foo < ActiveRecord::Base
class << self
def get_all_foo
@foo || Foo.find(:all)
end
end
end
Is it ok to cache this data so you don't constantly reload it from the
database? How long does @foo last? Just for the length of one request
or until the server is restarted?
Thanks,

I believe that this will only last for the duration of a request.
If you want it to be persistant, you could put it into the
environment.rb file and it would persist over many calls.
Probably a better way to do this is to use memcache though. There
are a number of good plugins that allow you to use this. A nice
one by Chris Wanstrath can be found at
