I''ve found quite a few posts on the subject, but no satisfactory answers. Maybe Rails just doesn''t support this yet. How do I create a url with a named RESTful route that also has parameters?

Hi all, I've released a new package to CRAN called 'yaml'. It allows R to parse YAML documents (http://yaml.org) into R objects, and there are a few methods to convert R objects into YAML. The package uses the Syck YAML parser (http://whytheluckystiff.net/syck/), the same parser that Ruby and other languages use to parse YAML. For more information, please visit:

Hi, I just posted a patch tot he rails trac for a bug we found where running symbolize_keys! on a HashWithIndifferentAccess will delete all items from the hash. Please make sure you either never call symbolize_keys!

I have a PHP box which was running NagiosQL on PHP4, and all of a sudden it stopped serving PHP pages. I went to http://boxIP/nagiosQL/testQL.php (that application's test page) and got the following error "PHP without mysql support, please install mysql module to php!" Not knowing what was broken, I attempted a "yum install php-*", but got the following message: --->

I''m having an issue installing rubygems-0.8.11 on 2 different boxes but get the same error on both.

Hello Rubyists, I am a bit stumped here. I want to extend the ''load_file'' method in the YAML module. Following along with the PickAxe example of making old methods do new things, I try this in irb: >> module YAML >> alias_method :orig_load_f, :load_file >> def load_file(*args) >> contents = orig_load_f(*args) >>

Hello all. I am looking for some feedback on an implementation. I''m writing a plugin that will log all model changes. I do not want to have to add a line a code for this functionality every time I create a model. Instead I create a table with the name <model>_changes. The basic stuff was easy: base.after_create {|model| model.log_create if model.has_backup_table?

Howdy -- I''ve been tracking down mem leaks (oh, the fun...), and I think there is a clue in objects.log. There are a few mentions of this file, but usually Zed saying "look at this file and it will help you".
