Include params/request information in Rails logger?

Question

Hi everyone,

I'm trying to get some more information into my Rails logs, specifically the requested URI or current params, if available (and I appreciate that they won't always be). However I just don't seem able to. Here's what I've done so far:

#config/environments/production.rb
config.logger = Logger.new(config.log_path)
config.log_level = :error
config.logger.level = Logger::ERROR

#config/environment.rb
class Logger
  def format_message(level, time, progname, msg)
    "**********************************************************************\n#{level} #{time.to_s(:db)} -- #{msg}\n"
  end  
end

So I can customize the message fine, yet I don't seem to be able to access the params/request variables here. Does anyone know if this is possible, and if so how? Or if there's a better way to get this information? (Perhaps even something Redis based?)

Thanks loads,

Dan

Answer 1

you should look in the request class

like puts request.uri.

check here for more detail http://api.rubyonrails.org/classes/ActionController/AbstractRequest.html

Answer 2

This should work! :) cheers.

logger.info({:user_agent => request.user_agent, :remote_ip => request.remote_ip}.inspect)

logger.info(params.inspect)

By the by.. This should be placed in your controllers action. Ex: If you place it in your create action it should also log the user_agent i.e the browser, remote_ip i.e the remote ip of the user and all the params.
