Easy question: Where do I put sweepers?
Trying to implement some sweepers to clean up my caching, but where do I
put them?
"ruby script/generate sweeeper" does nothing.

Are cache sweepers used?
After drawing many virtual blank stares in the IRC channel and finding
zero results on the wiki for ''sweeper'' I''m left to wonder whether
these are actually officially supported, or are on their way toward
being deprecated. Is there a better way of expiring caches on model
saves and deletions?
Sincerely,

"Undefined method merge" when using sweeper
Hi,
I''m trying to use sweepers for the first time and got a problem - I
get "undefined method `merge'' for "/signature/
f2d7c7c66450b169.html":String". The "/signature/f2d7c7c66450b169.html"
part of the error message is the cached page.
Here''s my sweeper:

Problems when using sweepers with postbacks
I''m using a cache sweeper class [1] to take care of some pretty complex
sweeping. However, there is a problem with the current implementation.
Namely, the sweeper gets called only when an action named in
cache_sweeper is called using GET. As many methods where sweeper would
be useful are using postback to send the form to the same action, this
causes the cache to get swept when

Making 'expire_fragment' available to a model?
I noticed a lot of repetition across different Sweeper models in my
app expiring the same fragments and so have been trying to move all
the expire_fragment calls into another model which the sweepers can
then use but it''s not working as I''d hoped..
I''ve created a CacheDestroyer model and want to be able to call
something to the effect of:

cache sweeper not getting called
Hi,
I''ve started to implement page caches but I''ve hit a brick wall getting
a sweeper to clear the cache when needed. It seems that any models that
I tell it to observe aren''t being observed properly. If I add the
sweeper to a controller the initialize method runs, but no matter what I
do the after_save/after_update callbacks aren''t running. Also if I try

Caching::Sweeper Access to Controller
Hello,
I''m running Mongrel 0.3.13.3, cluster 0.2.0, and Rails 1.1.6 and I
have a problem with a sweeper not having access to the controller
instance.
NoMethodError (undefined method `session'' for nil:NilClass):

Cache Sweepers and runner scripts that act on models?
I created a script that I call by ''./script/runner -e production
UpdateItems.get_new_items()'', which basically calls the model Item:
Item.create(attributes...)
I''ve set up a cache sweeper which removes caches after each
create/destroy/update on Item, and it works fine when accessing
controllers via the web server, but apparently doesn''t work via runner.

Expiring Cache Fragments and fcgi
First let me say that Rails caching is very very cool. The traffic
(and responsiveness) I''ve saved by added 10 lines of ruby code would
be enourmous, if I actually had traffic... ;)
Sweepers as observers are great, btw. Since every page of my side is
dynamic, once I did some DB optimization I''m caching the content of
the index page which was taking the bulk of the time to load

Fragment caching and pagination
I''m just getting my hands dirty with caching. The pages I want to cache have
some user specific data on them (for example "log out"). That sent me down
the route of fragment caching. One of the things I want to pagination is a
paginated list. My question is how is pagination and query strings handled
with fragment caching? Does each page get its own fragment and query string

calling controller and caching from a sweeper class
[cross-posting to rails and typo lists]
Hi,
I''m tinkering with the code for typo, a rails-based blog engine.
Typo has an XmlController with actions "rss" and "atom" which generate feed.xml
files, and it uses a caches_page declaration to cache the files that get
generated by those actions. It also has a Sweeper (Observer) class that expires
those cached files when a

cache_sweeper
Hi,
Why is cache_sweeper not a documented method? I was pretty sure it
used to be, but I could be wrong. I can''t seem to find any
information on it anymore in the online docs.
As a side note, looking at the code for cache_sweeper it appears to
only work with the :only option, not :except (ignores it)... what''s
the reason for this?
Thanks,
Andrew

Expiring cached actions outside of ActionController
In the site I''m building, my models are *almost* never updated within
ActionController-- all new data comes in via command line scripts
manipulating ActiveRecord directly.
Can anyone offer any hints about expiring cached actions without Sweeper?

trouble expiring cached pages
I''m having a bear of a time getting my cached pages to expire. Maybe
one of you guys can help me out. I''ll show my sweeper and then my log
to show that it "should" be working.

Engines 1.1.2
I''ve just pushed out a new bug-fix release for the Engines plugin.
Most notably, it''s now super careful (to the point of paranoia) about
ensuring that the right version of Rails is loaded, and should no
longer cause any issues where it ignores vendor/rails. Full CHANGELOG
is here:

Samba PDC not creating roaming profiles
Hi All,
I have recently moved my PDC from a linux suse 7.0 box to a
Solaris 8 server. I have downloaded the samba 2.2.8a and
installed it without any errors.
I used my old smb.conf and made the neccasry changes to it, I
have pasted it below.
I don't receive any errors, it just ends up using a local profile and
doesn't bother to update it to the server.

Need HELP changing link_to_remote to a button
I would really appreciate some help with changing a link_to_remote call to a button of some sort. Here''s a little background.
On the page there are two <div>s. One is a form that lets the visitor enter items. The second <div> is where the entered items get displayed, each in it''s own item <div>.
Each item <div> has two <span>s. The first one
