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/default/header_bg.gif" for 127.0.0.1 at 2011-06-10 17:30:45 -0400

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。
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
将以下代码放在config/initializers/quiet_assets.rb中
if Rails.env.development?
Rails.application.assets.try(: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'] =~ %r{^/assets/}
call_without_quiet_assets(env)
ensure
Rails.logger.level = previous_level
end
alias_method_chain :call, :quiet_assets
end
end
更新:它现在也适用于Ruby on Rails 3.2(以前的尝试修复了before_dispatch，现在我们将改为根机架调用)
更新:一个合适的机架中间件解决方案(而不是脆弱的alias_method_chain)来自@macournoyer https://github.com/rails/rails/issues/2639#issuecomment-6591735
