Hello,
for the world cup I've updated the sportweb command line tool [1] that
lets you browse your local sport.db / worldcup.db with a built-in
instant web admin server (and rails engine).
Browse all world cups (from Uruguay 1930 to Russia 2018) or build
your own sport league / tournament.
Cheers. Prost. Enjoy the beautiful game with ruby (and rails).
