route_for_sinatra(env) click to toggle source

For bare Sinatra, our override on process_route captures the last route into the environment for us to use later on

# File lib/new_relic/agent/instrumentation/sinatra/transaction_namer.rb, line 48
def route_for_sinatra(env)
  env["newrelic.last_route"]
end
route_name_for_padrino(request) click to toggle source

For Padrino, the request object has a copy of the matched route on it when we go to evaluating, so we can just retrieve that

# File lib/new_relic/agent/instrumentation/sinatra/transaction_namer.rb, line 54
def route_name_for_padrino(request)
  request.route_obj.original_path
rescue
  nil
end

  verb = http_verb(request)

  route_text = route_text.source if route_text.is_a?(Regexp)
  name = route_text.gsub(%r{^[/^\A]*(.*?)[/\$\?\z]*$}, '\1')
  name = ROOT if name.empty?
  name = "#{verb} #{name}" unless verb.nil?
