print standard-looking messages during migration

metavida · Sep 16, 20088 thanks

Within a migration file you can use the say_with_time method to print out informational messages that match the style of standard migration messages. See the say method also.

say_with_time "migrate existing data" do
# ... execute migration sql ...
end
#=> "-- migrate existing data"
#=> "   -> 0.0299s"

Include items affected in output

If the result returned from the block is an Integer, the output will include a message about that number of "rows" in addition to the elapsed time.

say_with_time "Some complex, custom work" do
counter = 0
# ... do some stuff here that increments the counter ...
counter
end

#=> "-- Some complex, custom work"
#=> "   -> 45.3725s"
#=> "   -> 52880 rows"
