如何防止Rails记录太多?这是我的production.log文件中的典型跟踪,许多部分,缓存命中......它在开发中很有用,但我不希望它在我的生产环境中。

在Rails 4中,将有一个清理日志的设置:
config.action_view.logger = nil
要在Rails 3中实现这一点,你必须修补ActionView:
module ActionView
class LogSubscriber < ActiveSupport::LogSubscriber
def logger
@memoized_logger ||= Logger.new('/dev/null')
end
end
end

您需要以不同方式设置config.log_level
。了解 Log Levels 。
例如,将以下内容添加到config/evironments/production.rb
config.log_level = :warn
您可能会设置为:debug
或:info
。

我把它放在我的初始化器中,以monkeypatch某些日志记录去调试而不是info:
module ActionView
class LogSubscriber
def render_template(event)
message = "Rendered #{from_rails_root(event.payload[:identifier])}"
message << " within #{from_rails_root(event.payload[:layout])}" if event.payload[:layout]
message << " (#{event.duration.round(1)}ms)"
debug(message)
end
alias :render_partial :render_template
alias :render_collection :render_template
end
end
module ActionController
class LogSubscriber
# Use debug logging for read_fragment
# %w(write_fragment read_fragment exist_fragment? expire_fragment expire_page write_page).each do |method|
%w(read_fragment).each do |method|
class_eval <<-METHOD, __FILE__, __LINE__ + 1
def #{method}(event)
return unless logger.info?
key_or_path = event.payload[:key] || event.payload[:path]
human_name = #{method.to_s.humanize.inspect}
debug("\#{human_name} \#{key_or_path} (\#{event.duration.round(1)}ms)")
end
METHOD
end
end
end
