Hello!

I have a Rails application, and now I’m trying to make a cgi-script  
out of Rails, but it should operate with Rails database and models.

Problem 1.  
Next script doesn’t seem to work everywhere:  
require ‘rubygems’  
gem ‘activerecord’, ‘=2.1.0’  
require ‘active\_record’  
require ‘yaml’

ActiveRecord::Base.establish\_connection( YAML.load\_file(“config/  
database.yml”)[‘development’] )

It works perfectly from console, but I cannot force it to work as a  
web page. It gives me “500 Internal error” page, and Apache log says  
me:  
[error] mod\_ruby: error in ruby  
[error] mod\_ruby: /usr/local/lib/site\_ruby/1.8/rubygems/  
custom\_require.rb:32:in `gem_original_require': no such file to load -- active_record (LoadError) [error] mod_ruby: from /usr/local/lib/site_ruby/1.8/rubygems/ custom_require.rb:32:in`require’  
[error] mod\_ruby: from /var/www/pc/api.rbx:6  
[error] mod\_ruby: from /usr/lib/ruby/1.8/apache/ruby-run.rb:53:in  
`load' [error] mod_ruby: from /usr/lib/ruby/1.8/apache/ruby-run.rb:53:in`handler’

My configuration:  
Ubuntu 7.10  
Apache 2.2.4 + mod\_ruby + mod\_fcgid  
Ruby 1.8.6  
Rails 2.1.0

Problem 2.  
One of my models “acts as tree” in the Rails application. But how can  
I make it to work in my cgi-script?  
I have tried:  
require ‘vendor/plugins/acts\_as\_tree/lib/active\_record/acts/tree.rb’  
But it doesn’t help.

Thanks in advance,  
Konstantin.

mod\_ruby hasn’t been maintained since 2006, and people generally avoid  
it. FastCGI is in a similar situations: people tend to avoid it because  
its implementation has all kinds of problems.

Maybe you should consider using Rack [1] in combination with Phusion  
Passenger [2] instead?

Do ‘require “config/environment”’. This will load the Rails environment  
and initialize plugins, but you will retain full control over how the  
application processes HTTP requests.
