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

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

Hi there, I''ve got a Rails app that''s a little unusual in that it maintains a database representation of a filesystem (for an image gallery). Thus, if the filesystem is essentially ''out of date'' then the controller''s list action will end up invoking a model update (which involves a filesystem scan). I''m using sqlite3 as this app will be

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'',

Hi all, Yesterday I released a new Rails plugin: cached_models. It allows to transparently use the internal Rails cache mechanism in your models, avoiding to write code for expiring policies. Example class Project < ActiveRecord::Base has_many :developers, :cached => true end class Developer < ActiveRecord::Base belongs_to :project, :cached =&g...

...me 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 under edge_rails as of a few weeks ago.

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

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

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)

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

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

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

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

Hi! I''m trying to extend ActiveRecord''s find method (Rails 1.0, Ruby 1.8.2), but I recognize a strange behaviour of the "alias_method" call. I wrote a very simple script to explain my problem: ------------------------------------------------------ module ActiveRecordExtension def self.included(base) base.extend(ClassMethods) base.class_eval do

Hi, Anyone got an idea of how many web and database servers I''d need to push out 10,000 dynamic pages per second? Fairly simple pages and database queries. I''d appreciate recommendations for hardware. The clients for this project are anticipating large amounts of burst traffic. Joe
