similar to: time based caching on rails pages.

Hi, i just wanted to say my sorries in advance (sorrie/sorry/sorri)...i have just started learning about the subject of caching, but unfortunately haven''t effictively managed to implement what i had learned. obviously it''s possible to cache a whole page, or action with the caches_page :x or caches_action :y methods, but for some reason it hasn''t really worked with

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

Hello. I wouldn''t mind getting some feedback about the use of fragment caching. I''ve got a series of relatively expensive database queries with their respective partials cached and everything is working fine. The problem is that do get this to work I''ve had to move the database queries from the controller into the view layer so as to avoid them being called if the

Hi all, I need to do some screen scraping from my rails app. Given an ethernet (MAC) adress, I scrape results from an internal web page that returns location and hostname. How can I cache the result from that screen scraping as to be polite to the scrapee? I would like to expire the results daily. In perl, I would use Cache::File. Can I use rails caching for this? What''s the best

Hi, I'm having difficulties with using DUNDi between two servers. If it were three I think I could control looping by limiting TTL, but with two I'm not sure how to prevent a loop causing bad things to happen. I've tried ttl=1 but things still blow up. The DUNDi configurations are pretty simple and work just fine in both directions as long as only one of them is using the switch

Hi all, I cannot find a clean way to create/edit an object that ''belongs_to'' another one, just by using form fields. I always need to explicitely unassemble it, store the master id in a hidden field, and then refetch the master from its id, and put it back in the object. To summarize: I want to create a new member, for a given project @project= ... @member =

Hi! First a little background: I'm thinking of compressing my Maildir's using dovecot's zlib support, and have run into a couple of problems. First of all, my files use the following formats: 1. 1260386673.000002.mbox:2,S 2. 1304920966.M241434P17342.mail,W=3152:2,S As you can see, both lack the S=<size> "basename flag", but the latter does have W=.

Hi Timo and other dovecot fans, why, when I'm trying to read certain "Drafts" emails that I just created, or edited, do the dovecot children die (or so I think). In mutt, the behaviour is that I "c =Drafts" then select the email and I get "connection closed to squeaky.rubberduck.com". In Mail.app - she just loops, trying to read those headers again and again

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

This feels more like a question to ask the core list, forgive me if I trespass. I''ve been trying to help one of my cow orkers get through a sticky problem. He''s got a fairly complex nested form to update a model and its children. He''s started adding some validations, and we''ve encountered a number of issues: First he had a validation on one of the child

Hi, I''m working on a website that has a very slow loading frontpage. I wanted to start by caching certain elements that have high load. For example, it loads the last 50 comments, along with the corresponding usernames, avatars and more. So I cached that fragment and created a sweeper that observes Comment and expires after every create or destroy action. However, I have two problems:

Hello, One of my machines I got a report about 3 vulnerable packages (php4, ruby, openssl) in tomorrows security run output, but in today's security run output all of them disappeared, but nobody upgraded or removed the affected packages. I reinstalled portaudit, refreshd its database, but now it reports 0 affected pakages. The pkg_info command lists that three packages, so they are

I noticed that there were quite a few files with version ids of '$FreeBSD$' when I ran mergemaster after an install of 4.8R. This isn't right is it? What are the consequences of installing over your files with unexpanded version ids? I would like to build a release(make release) and want to know if I can continue or if this is going to be a problem for future

Thank you for the rapid response. I will try and investigate getting answers to some of your points but I'm a little new to Solaris so I'll need some time. Glancing at the configure output, it looks like it built against v0.1.7 of libusb (yes i think that is derived from the one you mention), checking for libusb version via pkg-config... 0.1.7 found checking for libusb cflags... checking

I have noticed that the image_tag helper method now appends a request parameter to the generated src attribute. With Rails 1.0/actionpack-1.11.2 I had <img src="/images/rss.gif" /> Now (1.1/1.12.1) I get <img alt="Rss" border="0" src="/images/rss.gif?1142366545" /> Is there any use for that number? Where does it come from? This is very far

I lost my "connection lost" error.. but now I''ve got a "Mysql::Error: MySQL server has gone away" error.. It comes from: /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.6/lib/active_record/connection_adapters/abstract_adapter.rb:128:in ''log''. I''m not sure if Rails / BackgroundRb uses it .. but i''ve got the mysql (2.7) gem

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

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:
