Example of a module before and after logging

1_before.rb

module Background

  def self.execute(user)
    if user.privileged? or transient_condition?(user)
      something_dangerous(user)
    end
  end
    
  def self.transient_condition?(user)
    user.first_name.start_with?(random_character)
  end
  
end

2_after.rb

module Background
  include Hatchet

  def self.execute(user)
    log.info "Entering execute(user:#{user})"

    do_something_dangerous = false

    if user.privileged?
      log.info "#{user} is privileged"
      do_something_dangerous = true
    elsif transient_condition?(user)
      log.info "#{user} satisfied transient condition"
      do_something_dangerous = true
    end

    if do_something_dangerous
      log.info "Doing something dangerous for #{user}"
      something_dangerous(user)
    else
      log.info "Not doing something dangerous for #{user}"
    end

    log.info "Exiting execute(user:#{user})"
  end
  
  def self.transient_condition?(user)
    log.info "Entering transient_condition?(user:#{user})"
    character = random_character
    log.info "Checking if first_name:#{user.first_name} starts with character:#{character}"
    result = user.first_name.start_with?(random_character)
    log.info "Exiting transient_condition?(user:#{user}) - return:#{result}"
    result
  end
