如何禁用 rails 4 缓存的日志记录 [英] How to disable logging for rails 4 caching

问题描述

如何禁用rails 4.1"中的缓存日志记录?具体来说，我试图摆脱这样的片段缓存日志条目:

How can I disable logging for caching in "rails 4.1"? Specifically I'm trying to get rid of fragment caching log entries like these:

Write fragment views/... (0.3ms)
Read fragment views/... (0.3ms)

推荐答案

这个怎么样?

# config/initializers/log_subscriber.rb
module ActionController
  class LogSubscriber < ActiveSupport::LogSubscriber
    %w(write_fragment read_fragment exist_fragment?
       expire_fragment expire_page write_page).each do |method|
      class_eval <<-METHOD, __FILE__, __LINE__ + 1
        def #{method}(event)
          return
        end
      METHOD
    end
  end
end

本地测试:

# config/environments/development.rb
config.action_controller.perform_caching = true

(通常的警告是在您自己的应用程序中仔细测试.这种方法有效"，但属于锤子方法，以后可能会困住您或其他粗心的程序员.)

(With the usual caveat to test carefully in your own app. This "works," but is the hammer method, and can trap you or other, unwary programmers later.)
