默認情況下，在Rails 3.1（RC1）下，（dev）日志中的鏈輪往往很冗長：Started GET "/assets/application.css" for 127.0.0.1 at 2011-06-10 17:30:45 -0400Compiled app/assets/stylesheets/application.css.scss  (5ms)  (pid 6303)Started GET "/assets/application.js" for 127.0.0.1 at 2011-06-10 17:30:45 -0400Compiled app/assets/stylesheets/default.css.scss  (15ms)  (pid 6303)...Started GET "/assets/default/header_bg.gif" for 127.0.0.1 at 2011-06-10 17:30:45 -0400Served asset /default/header_logo.gif - 304 Not Modified  (7ms)  (pid 6303)Served asset /default/header_bg.gif - 304 Not Modified  (0ms)  (pid 6246)Served asset /default/footer_bg.gif - 304 Not Modified  (49ms)  (pid 6236)...我想降低詳細程度或完全禁用它。我假設有一個干凈的方法來禁用或減少日志記錄的冗長性，方法是在其中添加一條environment.rb或多條配置行development.rb以config.active_record.logger = nil使ActiveRecord SQL語句靜音。
