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

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 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 Thus, if the filesystem is essentially ''out of date'' then the controller''s list action will end up invoking a model update (which involves a filesystem scan).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

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

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

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

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

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

Any ideas how I can submit say, a person ID instead of the person''s name on an autocompleter input field? Surely this is a common need. Thanks! Daniel

Can acts_as_ferret search only one of the inherit models in the hierarchy of STI models? Say you have Contents, with types articles and comments. I know that you do Contents.find_by_contents, but can you also create indexed for Comment and Articles? Thanks for you help Miguel -- Posted via http://www.ruby-forum.com/.

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

How do I write a test which proves something like "Post :has_many Comments" and "Comment :belongs_to Post"? It doesn''t seem to be covered in "A Guide to Testing the Rails" on manuals.rubyonrails.com. Cheers, Robert. -- Posted via http://www.ruby-forum.com/.

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 => true end # Automatic cache, all

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.

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

I designed out a mostly attribute driven database. Originally i was going to use PHP, but have now decided to use RoR. Being able to use the built in OR functionality would be nice, but I am not sure how well it melds with attribute dbs. If anyone can give me some pointers, I would really appreciate it (especially since this is my first endeavor and on an important project as well).

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
