I would like to sort some of my models better into different folders.  
Unfortunately when I do so it is unable to find the models.

I have updated the boot.rb file to:  
#Rails::Initializer.run(:set\_load\_path)  
Rails::Initializer.run do |config|  
config.frameworks -= [:action\_web\_service]

```
config.load_paths += %W[
  #{RAILS_ROOT}/app/models/
  #{RAILS_ROOT}/app/models/associative/
]

```

end

Rails still does not seem to be able to find the models within the  
“associative” folder.

Here is the contents of the file models/associative/person\_address.rb:

class PersonAddress \< ActiveRecord::Base  
end

This post [Simpler irb — err.the\_blog](http://errtheblog.com/post/5) is where I saw how to tweak the  
root.rb file.

Thanks for the help
