I recently upgraded to Rails 2.2.2 and refactored some of my rails code  
to use the config.gem functionality. In doing so, I noticed some odd  
behavior when trying to start the DrbServer. Essentially, the DrbServer  
will not start unless I have the “require 'acts\_as\_ferret” statement  
below in environment.rb. I thought the gem.config would have been  
enough, but apparently not.

– start environment.rb –

Rails::Initializer.run do |config|

[…]

# Requires acts\_as\_ferret must be here, can’t figure out why

require ‘acts\_as\_ferret’

config.gem ‘acts\_as\_ferret’, :version =\> ‘0.4.3’  
config.gem ‘ferret’, :version =\> ‘0.11.6’

[…]

end

– end environment.rb –

Here’s the error message I receive when the require is left out.

– error –

me@machina $ script/ferret\_server -e production start  
undefined method `acts\_as\_ferret’ for #Class:0x22f9bec

– end snip –

Any ideas if this is normal?

I don’t use the AAF gem, but do have a require statement in a  
initializer in config/intializers that pulls in acts\_as\_ferret. Any  
chance you can supply a more detailed back trace that sheds some light  
on what class is causing trouble? Do you also have trouble booting  
script/console?

For the DrbServer to start successfully, I must include a

require ‘acts\_as\_ferret’

…statement in my environment.rb file.

However, script/console and script/server startup just fine without the  
require statement.

Here goes…

– script/ferret\_server –

#!/usr/bin/env ruby

begin  
require File.join(File.dirname( **FILE** ),  
‘…/vendor/plugins/acts\_as\_ferret/lib/server\_manager’)  
rescue LoadError

# try the gem

require ‘rubygems’  
gem ‘acts\_as\_ferret’  
require ‘server\_manager’ # \<-- This is line 9  
end

– end script/ferret\_server –

Notable points of interest:

- article.rb is a model and has a “acts\_as\_ferret” hook at line 35
- Line 35 of environment.rb is the “Rails::Initializer.run do |config|”  
start block. Within it I have a config.gem ‘acts\_as\_ferret’ statement.

My hunch is that config.gem is not loading things in a way that is  
compatible with DrbServer. Ideas?
