if you name each of your (game)set input fields something like "set[]"
then rails will parse the parameters as an array. This way you will
give you a params hash like:
{ 'match' => { 'sets' => ['1','3','7']} }
This means in your model you can define a virtual attribute called
'sets' like:
def sets= scores
self.score = scores.map(&:to_i).sum
end
