Courtesy of The Robot Co-op. $ yes | sudo gem install cached_model Or, you can download cached_model and memcache-client (our zippy-fast memcache library, required) from: http://rubyforge.org/frs/?group_id=1266 I don''t have the README posted for making cached_model work online yet, so here it is: = CachedModel Rubyforge Project: http://rubyforge.org/projects/rctools/ == About

Hi - Just downloaded and installed the memcache-client and cached_model gems and am trying to test it out on a development setup. I added this to my environment/development.rb CACHE = MemCache.new :c_threshold => 10_000, :compression => true, :debug => true, :namespace => ''eztrip'',

I started using robotcoop''s CachedModel class in my project but have encountered problems when using it with the acts_as_ferret plugin. It seems it doesn''t index everything in my STI model, also if I do a search from my base STI class I get a result count but no results. If I run the same search from one of the children STI models I get the appropriate results (if the information

Is a find_by_sql query cached with memcached and cached_model (http://dev.robotcoop.com/Libraries/)? Looks like the answer is no. Is there a reason for this? I have a lot of very complicated querys with a lot of unions, subquerys and joins that would greatly benefit from the cache. Going through the code I can see that the find_by_sql method is changed in cached_model.rb, but it does not call

The new version of cached_model features bug fixes and tests! Bugs fixed: Updating a model no longer stores associations into the cache. This could cause strange, hard-to-debug bugs when an invalid set of assocations was retrieved along with a cached model. Reloading a model refreshes the cache. When CachedModel::find can''t understand query params and a single result is

Can any one help explain this output in my log. I have memcache-client and cached_model setup for a model City but when I run my app, this is the output I get (this is on a second pass so theoretically the data is already in the cache). MemCache Get (0.000469) active_record:City:1802387 City Load (0.001015) SELECT * FROM cities WHERE (cities.id = 1802387) LIMIT 1 MemCache Set (0.000776)

Hey All ! I ended up browsing to Eric Hodel''s blog the other night, and found his entry about the new cache_model and memcache-client. Now, it looks like it''s "officially" out in the open: http://weblog.rubyonrails.com/articles/2006/01/20/caching-models-with-memcached In my application, I''ve been staying away from caching my models, and instead just doing

It looks like cached-model is broken again under rails 1.1. Can anyone confirm? Note that the exception below indicates it''s trying to treat CachedModel as the class name of the model, rather than using the proper class name (which is Entry in this case, and the table called entries). This is a model using Single Table Inheritance and acts_as_tree, and worked just fine under 1.0 and

Hi all - I am trying to get rails to use memcache for sessions and fragment caching. I''d also like to use the same connection for general caching of this and that. I''m following the instructions here: http://wiki.rubyonrails.com/rails/pages/HowtoChangeSessionStore and hitting a brick wall. I''m using the new memcache-client since from what I''ve read

I''ve been following the instructions here http://nubyonrails.com/ articles/read/716 on how to get started with memcached. Starting up ./script/console production I get at couple of deprecation warnings: <snip> ./script/console production Loading production environment. DEPRECATION WARNING: model is deprecated and will be removed from Rails 2.0 See

Any suggestions on applications that involve alot of calcualtions on a fairly large data set? My app uses a set of raw data ~5k, applies some default/override rules on the raw data and does some calculations on the data in combination with a list of assumptions. A ranked list along with detailed metrics is generated. The end user can manipulate some of the rules and assumptions to generate

I''m at the bloody forehead stage, so I figure it''s time to ask. After installing the robot coop''s memcache-client which everyone apparently recommends, it refuses to work because the rails cache.rb is invoking the read() method on the cache, which it _does not have_. Their library has get() and put() but no read() and write() as rails expects. What gives? Is

I was just testing the memcache server on a Windows box and had set it up as a Windows Service and to my surprise (or my shock really) it was using 47+ meg of ram with no data even loaded in it yet. Has anyone else used the Windows port of memcached for their Rails projects and if so how much ram was it using? Does memcached use less memory on Mac OS X or Linux than Windows? Thanks for any

I''m looking at an application that has 30+ lookup tables. By that I mean your typical (id, description, created_on) affairs that contain locations, zip codes, contract types and what not. Things that rarely change, and are maintained by administrators. It''s well known that when you have many lookup tables in the schema, eager loading is not good enough anymore, and you need to

Just curious, is there anyway to use memcache with a ferret index? Thanks, Ray -- Posted via http://www.ruby-forum.com/.

Hi Alberto, With systemd it will be as easy as creating additional unit files ( one for > each memcached instance) with its corresponding config file. That should > allow to stop / start / restart each memcache instance individually while > also being systemd compliant. Thanks for the info and for the examples. It really does make sense the way you explain it. Thanks for letting me

Hi, in the release notes of 2.1.9 I read that dovecot supports memcache and redis backends for userdb/passdb authentication. This is very interesting for me and should reduce queries and database load of our mysql servers. My idea is to use memcache or redis in our IMAP/POP3 proxies in front of our backend servers. So I would like to try out if it's possible to store proxy information of our

Hi, I am trying to do fragment caching using :mem_cache_store. However, when I compare it to fragment caching using :file_store, it seems to be a lot slower. Here are the results: uncache Completed in 2.20246 (0 reqs/sec) | Rendering: 2.19891 (99%) | DB: 0.00017(0%) | 200 OK [ http://127.0.0.1/] using file_store Completed in 0.00952 (105 reqs/sec) | Rendering: 0.00702 (73%) | DB: 0.00000(0%)

Hi Everyone, There''s quite a few of you who have contacted me about Mongrel suddenly stopping. After a lot of investigation, I found that the common thread between all of you is memcache and Eric Hodel''s memcache-client. People who were running this combination would have intermittent pauses and investigating the stalled mongrels showed that memcache-client was waiting for
