how would I map relationships for world cup football matches.
Currently in my app I have Countries, that's it, all 32 competing nations are represented, with flags and details working great.
I'd like to introduce two new models (Match and Stadium).
A football match is obviously between two Countries in a Stadium.
How could I set that up best?
Country has_many Matches
Match has_many Countries belongs_to Stadium
Stadium has_many Matches
Bit confused as a Match will only ever be between two sides of course. Do I require habtm? What's best to do here.
