Send exception without re-raising about appsignal-ruby

[thijsc]

Good point, these two use cases should be possible in a nice way. We're going to look at this and see if we can find a good solution.

listen_for_exception and send_exception were originally meant to track exceptions in rake tasks (or background jobs) .
It sounds like a good idea to have a way to track an exception within an request.

In the meantime you can try the following
(if you are willing to play with Appsignal internals, also i didn't test this :))

class PushNotification < ApplicationController
  rescue_from Exception, with: :render_error

  def update
    # do the magic that may throw an exception
    respond_to do |format|
      format.json { render text: '', status: 200 }
      format.html { render text: '', status: 200 }
    end
  end

private
  def render_error(exception=nil)
    # Transaction.current checks if we have an active transaction (e.g. Rails request) 
    # and add_exception adds an exception to the request/transaction
    if exception && Appsignal::Transaction.current
      Appsignal::Transaction.current.add_exception(exception) 
    end

    respond_to do |format|
      format.json { render text: '', status: 200 }
      format.html { render text: '', status: 200 }
    end
  end
end

@thijs we should probably make this available on the Appsignal module

We shipped this today in version 0.6.6 of the gem, info on how to use it: http://docs.appsignal.com/tweaks-in-your-code/handle-exceptions.html#toc_5

@brickattack Could you try this out and let us know if it works for you?
