将ActiveStorage日志静音

Question

ActiveStorage充斥我的开发日志,所以我淹没在页面上的图像请求.有没有办法静音活动存储或至少减少日志条目,以便我可以再次使用我的日志？

例如,对于通过ActiveStorage访问的页面上的每个图像,我得到以下其中一个:

任何帮助将不胜感激.:)

Answer 1

我正在使用Lograge Gem来隐藏这些请求。

config.lograge.ignore_actions = [
  "ActiveStorage::DiskController#show",
  "ActiveStorage::RepresentationsController#show"
]

Answer 2

根据我设定的EvilMartians的文章

config.active_record.verbose_query_logsfalse里面的选项application.rb。

它部分解决了问题。

似乎 Active Storage 人员认为最详细的日志记录非常重要。所以现在关于文件的日志与存储的文件在磁盘上的大小相同。

而最让人恼火的是这些消息的级别是INFO。我不明白为什么它不是调试...

Answer 3

我发现这是最简单的（也许但不是万无一失的）解决方案，可以更轻松地开发。它使用标准 Rails 日志，仅替换其默认格式化程序。适用于 Rails 6，可能也适用于 Rails 5。

将以下代码放入config/environments/development.rb：

Rails.application.configure do
    .
    .
    .

  class MyLogFormatter
    def initialize
      # Suppress is an array of request uuids. Each listed uuid means no messages from this request.
      @suppress = []
    end

    def call(severity, datetime, progname, message)
      # Get uuid, which we need to properly distinguish between parallel requests.
      # Also remove uuid information from log (that's why we match the rest of message)
      matches = /\[([0-9a-zA-Z\-_]+)\] (.*)/m.match(message)

      if matches
        uuid = matches[1]
        message = matches[2]

        if @suppress.include?(uuid) && message.start_with?("Completed ")
          # Each request in Rails log ends with "Completed ..." message, so do suppressed messages.
          @suppress.delete(uuid)
          return nil

        elsif message.start_with?("Processing by ActiveStorage::DiskController#show", "Processing by ActiveStorage::BlobsController#show", "Processing by ActiveStorage::RepresentationsController#show", "Started GET \"/rails/active_storage/disk/", "Started GET \"/rails/active_storage/blobs/", "Started GET \"/rails/active_storage/representations/")
          # When we use ActiveStorage disk provider, there are three types of request: Disk requests, Blobs requests and Representation requests.
          # These three types we would like to hide.
          @suppress << uuid
          return nil

        elsif !@suppress.include?(uuid)
          # All messages, which are not suppressed, print. New line must be added here.
          return "#{message}\n"
        end

      else
        # Return message as it is (including new line at the end)
        return "#{message}\n"
      end

    end
  end

  config.log_tags = [:uuid]
  config.log_formatter = MyLogFormatter.new
    .
    .
    .
end
