config.logger = Logger.new("log/production.log", 5, 10 * 1024 * 1024)
config.logger = Logger.new(config.paths["log"].first, 5, 10.megabytes)
#日別
config.logger = Logger.new("log/production.log", 'daily')ちなみにconfig.paths["log"].firstは"log/production.rb"が格納されている。pathsは複数のパスを管理することができるPathクラスのオブジェクトだがここでは1つの要素しか格納されていない模様。
