您可能自己知道,有时您必须通过 Rails 控制台在实时生产机器上执行任务...

我通常这样开始:bundle exec rails console -e production

但由于它是生产机器,我想将 Rails 控制台的所有输入和输出记录到一个文件中,例如到 /home/sshuser/myproject/console_sessions/2016_09_09__14_33_33.txt

有人知道怎么做吗?我想自动启动记录器,但前提是我运行控制台?

(我正在运行 Rails 3.2)谢谢!

最佳答案

这是一个解决方案,整个系统只有一个文件,不修改 Rails 项目,也不修改控制台命令。

你可以把它放在你的 ~/.irbrc 中,我用 Ruby 2.1.5 和 Rails 3.2/4.0/4.2 测试过它:

# ~/.irbrc for http://stackoverflow.com/questions/39411783/log-rails-console-always-to-file-in-production-env
if defined? Rails
puts "Loading configuration for Rails console from #{__FILE__}"
time = Time.now.strftime('%Y_%m_%d__%H_%M_%S')
log_file = File.join(Rails.root, "log", "rails_console_#{Rails.env}_#{time}.log")
#log_file = "/home/sshuser/myproject/console_sessions/#{time}.txt"
puts " logging to #{log_file}"
logger = Logger.new(log_file)
Rails.logger = logger
ActiveRecord::Base.logger = logger if defined? ActiveRecord

# Intercepts STDIN from IRB
module Readline
module History
def self.write_log(line)
Rails.logger.info(line)
end

def self.start_session_log
write_log("# session start: #{Time.now}")
at_exit { write_log(" # session stop: #{Time.now}") }
end
end

alias :old_readline :readline
def readline(*args)
ln = old_readline(*args)
begin
History.write_log("STDIN : #{ln}")
rescue
end
ln
end
end

# $stdout writes to STDOUT and Rails.logger
# $stderr writes to STDERR and Rails.logger
class MultiLog
def initialize(io)
@io = io
@desc = io.inspect[/STD\w+/]
end

def write(str)
Rails.logger.info("#{@desc} : #{str}")
@io.write(str)
end

def close
@io.close
end
end

$stdout = MultiLog.new(STDOUT)
$stderr = MultiLog.new(STDERR)

Readline::History.start_session_log
end

对于 Pry ,你应该使用这个 ~/.pryrc :

# ~/.pryrc for http://stackoverflow.com/questions/39411783/log-rails-console-always-to-file-in-production-env

if defined? Rails
puts "Loading configuration for Rails console from #{__FILE__}"
time = Time.now.strftime('%Y_%m_%d__%H_%M_%S')
log_file = File.join(Rails.root, "log", "rails_console_#{Rails.env}_#{time}.log")
#log_file = "/home/sshuser/myproject/console_sessions/#{time}.txt"
puts " logging to #{log_file}"
logger = Logger.new(log_file)
Rails.logger = logger
ActiveRecord::Base.logger = logger if defined? ActiveRecord

# Intercepts STDIN from pry (from http://www.hardscrabble.net/2015/how-to-log-all-input-in-your-pry-rails-console)
class LoggingReadline
delegate :completion_proc, :completion_proc=, to: Readline

def readline(prompt)
Readline.readline(prompt).tap do |user_input|
Rails.logger.info("STDIN : #{user_input}")
end
end
end

Pry.config.input = LoggingReadline.new

# $stdout writes to STDOUT and Rails.logger
# $stderr writes to STDERR and Rails.logger
class MultiLog
# Needed for #tty?, #flush : https://github.com/pry/pry/issues/1464
def method_missing(sym,*p)
@io.send(sym,*p)
end

def initialize(io)
@io = io
@desc = io.inspect[/STD\w+/]
end

def write(str)
Rails.logger.info("#{@desc} : #{str}")
@io.write(str)
end

alias_method :print, :write
end

$stdout = MultiLog.new(STDOUT)
$stderr = MultiLog.new(STDERR)

end

它将控制台输入、输出和错误以及数据库查询保存到指定的文件中。例如:

 ~/www/my_movies> bundle exec rails console -e development                                                                  
Loading development environment (Rails 4.0.4)
Loading configuration for Rails console from /home/ricou/.irbrc
logging to /home/ricou/www/my_movies/log/rails_console_development_2016_10_28__11_58_41.log
2.1.5 :001 > Movie.first
=> Est - Ouest
2.1.5 :002 > puts 2+2
4
=> nil
2.1.5 :003 > exit

输出这个日志文件:
