well rather than permuting the names, i'd work with the teams directly, i.e. Team.all.permutation(2) do |team1, team2| Fixture.create(...) end and then in that block create the fixture object for team1 versus team 2. Note that if you had teams a,b,c then you'll get both a,b and b,a as 2 different permutations. This might be what you want (e.g. if in a season each pair meets twice, swapping who is the home team and who is the away team), but if it isn't then try using combination instead of permutation Fred > > Anybody got any ideas how this is possible or an alternative way of > generating the fixtures? > > Thanks for help in advance! :) > > -- > Posted viahttp://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
