[ANN] Time based fragment caching plugin

Rails
1

I’ve written a plugin to allow for time based fragment caching. It lets
you do things like:

<% cache ‘fragment_name’, 10.minutes.from_now do %>

something intensive which will be cached for 10 minutes

<% end %>

Also, there’s a convenience method so that in your controllers you can
do:

when_fragment_expired ‘fragment_name’, 10.minutes_from_now do
@stuff = do_something_intensive
end

This will check the fragment cache, see if it’s expired and if so it
will execute the code in the block. It deals with expiring the fragment
itself, so if using this you don’t need to have the expiry time in your
views and you can keep yourself DRY by having the expiry time in just
one place.

Hopefully it’s of use to someone.

I have recently released a very similar plugin, except mine is designed
to
work with the robot coop memcache-client (memcache supports time expiry
without using meta fragments)
Syntax is similar to Richard’s

<% cache ‘key’, :expire => 10.minutes do %>

stuff

<% end %>

Sorry if this was already posted, I don’t remember if I wrote to the
list
or not.
