Add current_user support

[mperham]

I'd love it if lograge would auto-support current_user logging, something like:

 config.lograge.custom_options = lambda do |event|
    { :uid => event.request.controller.current_user.id }
  end

We find it vital for debugging and 'watching' how a user got into a particular state.

I've started working on a branch that brings support for tagged logging to lograge, which would be much more fitting in this case, as it'd utilize something Rails already has support for.

I've been looking for a solution to this issue because that would be tremendously useful. You can use a Rails' hook method in Instrumentation called append_info_to_payload. Just override that in your ApplicationController:

def append_info_to_payload(payload)
    super
    payload[:uid] = current_user.id if logged_in? 
end

Then you can use:

config.lograge.custom_options = lambda do |event|
    { :uid => event.payload[:uid] }
end

We are using config.log_tags in Rails to add the user_id. If we switch to lograge, should we use custom_options instead?

@nathany I'm going thru this issue myself. The main thing I'm noticing is that lograge's payload would only apply to things it is subscribed to (namely process_action.action_controller).

However if you have any generic logging happening elsewhere the application you want the tags attached to you will still need to use the tags (i.e a log even happening within model code where you want the current user_id included in the log method w/o knowing at the model level what it is.

But if you just want it for the general "request completed" lograge will do the trick

[nathany]

After switching to append_info_to_payload, I'm actually likely it better than what we were doing with config.log_tags before setting up lograge (grabbing the session id and doing a separate lookup).

+1000 for this feature builtin in lograge.

just want to say freegenie's option from '12 still works great in Rails 4.2 / Ruby 2.2

for Devise there are a few ways to check for logged in - I went with

def append_info_to_payload(payload)
    super
    payload[:uid] = current_user.id unless current_user.nil?
end

@tongboy instead of current_user.nil? - you should use user_signed_in?
