I have a rails application in that I have modules inside `/app/adapters/UDB/` folder. The module is not loading. I have added the following in `application.rb`

`config.autoload_paths += Dir["#{config.root}/app/adapters/**/*"]` 

I am calling module from model file `/models/userinvite.rb` 

```
   def update_cassandra
    ypusers = UDB::YpRewards.new.ypusers
    ypusers.execute("UPDATE invitation_backlog SET invitation_code = '#{invitation_code}', invitation_sent_date = #{invitation_sent_date.to_i * 1000}, invited_by = '#{invited_by}' WHERE email_address = '#{email}'")
   end

```

/app/adapters/UDB/yp\_rewards.rb

```
   module UDB
   class YpRewards
     def initialize

     end
     def ypusers
        @ypusers ||= UDB::Connection.new.connection.connect('ypusers')
     end
   ...

```

Please help me solving it.
