Group countries per continent

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

HTH,
