Adding Modules to ActiveRecord

Hi,

I need to add some methods to all my models. These methods are likely to be used in pretty much every Rails project I work on for the foreseeable future, so am guessing that it would be best to add them to ActiveRecord.

The methods are all in their own modules, which include additional modules, and are all packaged inside a single Manager module.

I have had a look into ActiveRecord, but don't know enough about ActiveRecord yet to dive in and change or add to it.

Could someone point me in the right direction?

Example

[code] manager.rb   module Manager

    # Constants Defined

    module PackageSearchResult       include Packager       include Result       include Searcher

      def method1         ...       end     end   end [/code]

How would I put Manager into ActiveRecord so that all my models get method1 by default?

Thanks

Paul
