在Ruby on Rails 3.1 (RC1)下，默认情况下，Sprockets在(dev)日志中往往相当冗长:
Started GET "/assets/application.css" for 127.0.0.1 at 2011-06-10 17:30:45 -0400
Compiled 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 -0400
Compiled 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 -0400
Served 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)
...
我想减少它的冗长程度，或者完全禁用它。
我假设在这两种环境中都可以通过添加配置行来禁用或减少日志记录的冗长性。Rb或发展。Rb类似于config.active_record。logger = nil沉默ActiveRecord SQL语句。
很多人对config.assets.logger = false的用法感到困惑。下面是它能做什么和不能做什么。
根据源文件:
将config.assets.logger设置为false将关闭服务的资产日志记录。
然而，这可能不是你想的那样。它只禁止sprocket“服务”日志，而不是Ruby on Rails actionpack请求日志。Ruby on Rails维护者在这里清楚地解释了这一点:
https://github.com/rails/rails/issues/4569#issuecomment-3594500
以链路为例，这样的日志是被禁用的:
已服务资产/jquery.同位素.js - 304未修改(0ms)
但像这样的对数不是
Started GET "/assets/jquery.同位素.js?Body =1" at 2012-01-20 23:16:46 -0500

前面提到的链接解决方案有助于:
https://github.com/evrone/quiet_assets
也如下所示，它为我工作得很好:
3.1(仅)(3.2中断before_dispatch)
app\config\initializers\quiet_assets.rb
Rails.application.assets.logger = Logger.new('/dev/null')
Rails::Rack::Logger.class_eval do
def before_dispatch_with_quiet_assets(env)
before_dispatch_without_quiet_assets(env) unless env['PATH_INFO'].index("/assets/") == 0
end
alias_method_chain :before_dispatch, :quiet_assets
end
3.2 Rails - Rack root tap approach
app\config\initializers\quiet_assets.rb
Rails.application.assets.logger = Logger.new('/dev/null')
Rails::Rack::Logger.class_eval do
def call_with_quiet_assets(env)
previous_level = Rails.logger.level
Rails.logger.level = Logger::ERROR if env['PATH_INFO'].index("/assets/") == 0
call_without_quiet_assets(env).tap do
Rails.logger.level = previous_level
end
end
alias_method_chain :call, :quiet_assets
end
