Learn how to actually integrate Trifle::Traces into your Rails app.

Rails

Instead of tracing every request ever made into your Rails app, there is better way to specify which requests are worth tracing. This implementation is using around_action controller callback.

Configuration

You need to include Trifle::Traces mixin into your controller and specify which controller actions you would like to trace.

# frozen_string_literal: true

class SessionsController < ApplicationController
  include Trifle::Traces::Middleware::RailsController
  with_trifle_traces only: %i[create]

  def create
    Trifle::Traces.trace('Lets steal some passwords!', head: true)
    # pls, this is not secure, dont do this!
    user = User.find_by(email: params[:email])

    if user && user.password == params[:password]
      Trifle::Traces.trace('Matching user') { user.id }
      Trifle::Traces.trace('Used password') { params[:password] }
      session[:user_id] = user.id
      redirect_to root_path
    else
      Trifle::Traces.ignore!
      redirect_to new_session_path, flash: {
        error: 'Uh oh! Thats a nono for the password.'
      }
    end
  end

  private

  def trace_meta
    [params[:email], params[:password]]
  end

  def trace_key
    "hack/sessions/#{params[:action]}"
  end
end
