Question

来自javascript背景，我在运行rails时发现命令行杂乱无章。每当发生某些事情时，我的命令行都会被一堆垃圾填满。 E.g：

[2013-06-19 20:25:53] WARN  Could not determine content-length of response body.
 Set content-length of the response or set Response#chunked = true

如何关闭它以便我只看到自己的日志（当然还有错误）？

感谢任何帮助！

Answer 1

尝试更改日志级别，默认为info。

来自指南：http://guides.rubyonrails.org/debugging_rails_applications.html#log-levels

Answer 2

更改config/environments/development.rb和/或testing.rb中的日志级别：

config.log_level = :error

可用的日志级别为：:debug，:info，:warn，:error，:fatal和:unknown，对应于整数0 - 5。

Answer 3

您可以关闭SQL查询。我知道他们占用了很多空间。

Answer 4

解决方案

./ .env

通常文件 .env 用于存储应用程序环境的所有重要/秘密属性。创建 .env （如果不存在）并添加代码：

RAILS_LOG_TO_STDOUT=true

./ config / environments / *。rb

编辑您的环境文件（例如./config/environments/development.rb）以创建可断开连接的日志记录系统。

Rails.application.configure do

  # ...

  if ENV['RAILS_LOG_TO_STDOUT'] == 'true'
    logger           = ActiveSupport::Logger.new(STDOUT)
    # To support a formatter, you must manually assign a formatter from the config.log_formatter value to the logger.
    logger.formatter = config.log_formatter

    # config.logger is the logger that will be used for Rails.logger and any 
    # related Rails logging such as ActiveRecord::Base.logger.
    # It defaults to an instance of ActiveSupport::TaggedLogging that wraps an 
    # instance of ActiveSupport::Logger which outputs a log to the log/ directory.
    config.logger    = ActiveSupport::TaggedLogging.new(logger)

    # config.log_level defines the verbosity of the Rails logger. 
    # This option defaults to :debug for all environments. 
    # The available log levels are: :debug, :info, :warn, :error, :fatal, and :unknown
    #config.log_level = :debug

    # config.log_tags accepts a list of: methods that the request object responds to,
    # a Proc that accepts the request object, or something that responds to to_s. 
    # This makes it easy to tag log lines with debug information like subdomain and request id -
    # both very helpful in debugging multi-user production applications.
    config.log_tags = [:request_id]
  end
end

用法

在 .env 中将RAILS_LOG_TO_STDOUT=true设置为打开控制台记录器

删除或注释行RAILS_LOG_TO_STDOUT=true，或在 .env 中将RAILS_LOG_TO_STDOUT=false设置为关闭控制台记录器
