默认情况下,在 Ruby on Rails 3.1 (RC1) 下,Sprockets 在 (dev) 日志中往往非常冗长:
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) ...

我想降低详细程度或完全禁用它。
我假设有一种干净的方法来禁用或减少日志记录的详细程度,方法是在其中一个environment.rb或development.rb类似的配置行中添加一个配置行来config.active_record.logger = nil使 ActiveRecord SQL 语句静音。
environment.rb
development.rb
config.active_record.logger = nil
将以下代码放入config/initializers/quiet_assets.rb
config/initializers/quiet_assets.rb
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(之前的尝试修复before_dispatch,现在我们将使用根机架call)
before_dispatch
call
alias_method_chain更新:来自@macournoyer https://github.com/rails/rails/issues/2639#issuecomment-6591735的适当的 Rack 中间件解决方案(而不是脆弱的)
