Things needed to log rails to papertrail.

rails_2_papertrail.rb

class MultiIO
  def initialize(*targets)
     @targets = targets
  end

  def write(*args)
    puts "writing"
    @targets.each { |t| t.write(*args) }
  end

  def close
    puts "closing"
    @targets.each(&:close)
  end
end

if Rails.env.development?
  require File.expand_path('../../lib/multi_io', __FILE__)

  papertrail    = RemoteSyslogLogger::UdpSender.new('logs.papertrailapp.com', 58918, program: 'piston')
  log_file      = File.open(AppRunway::Application.config.paths['log'].first, "a")
  log_file.sync = true
  
  AppRunway::Application.config.colorize_logging = false
  
  Rails.logger = Logger.new( ::MultiIO.new( log_file, papertrail ) )
  Rails.logger.formatter = proc do |sev, time, prog, msg|
    msg.gsub! /^\n*/, ""
    pad = " " * (5-sev.length)
     "[#{sev}]#{pad} #{time} - #{Process.pid}: #{msg}\n"
  end
