Hi guys,

I have a table that has a country column (:string). Now I need to group  
together all the countries that are in Europe.

Any ideas on how I would approach this? (quickfix wise)

Regards,

Vincent

1. Add continent as an attribute to Country, access collections via  
named scope

2. Create a Continent model where Continent has\_many countries,  
Country belongs\_to continent
