undefined method table_name

[reiz]

I tried to integrate this lib into a running application. The action on the controller is called, but it throws an exception:

NoMethodError (undefined method table_name' for Product:Class): rails3-jquery-autocomplete (1.0.7) lib/rails3-jquery-autocomplete/orm/active_record.rb:7:inget_autocomplete_order'
rails3-jquery-autocomplete (1.0.7) lib/rails3-jquery-autocomplete/orm/active_record.rb:19:in get_autocomplete_items' rails3-jquery-autocomplete (1.0.7) lib/rails3-jquery-autocomplete/autocomplete.rb:55:inblock in autocomplete'

It seems that the lib tries to use active_record, but I am using MongoID. Actually I am not sure why this should work with Mongo. In the tutorial I am missing the point where the orm will be selected. How can I tell the library to use MongoID instead of active_record?

Thanks.

In the mean time I implemented the auto-complete function with pure jQuery and a little bit Ruby code. But I still would like to know why this gem didn't worked out for me.

Many Thanks,
Robert

the gem needs to appear in Gemfile after the mongoid gem
