Server-side events with Segment.io for free
The problem with Segment.io Analytics.js is that binding to a form submit doesn't mean that the action was success. I've found a nice little work around so that I can fire events off from the server
First add a track_event method to your Application Controller
class ApplicationController < ActionController::Base
def track_event(*args)
json_array = args.to_json.stripe
json_args = json_array.slice(1, json_array.length - 2)
flash[:events] ||= Array.new
flash[:events] << json_args
end
endThen we a way to display these "flash events" in our template. So create a helper
module LayoutHelper
def analytics_events
Array(flash[:events]).map do |event|
"analytics.track(#{event})"
end.join("\n")
end
endLastly, add the following to your template:
script == analytics_eventsNow server side analytic events are as easy as
track_event('Created account', plan: 'Free')Written by Christopher Garvis

Nice post and very helpful, have some code they may help others:
1) I think you meant to use strip instead of stripe in the track_event method.
2) Also, for people unfamiliar with HAML here is the equivalent code in ERB:
<%= javascript_tag do %>
<%= analytics_events.html_safe %>
<% end %>3) Here's a little refactor that may help in clarity:
track_event in application_controller.rb
def track_event(event, options = nil)
json_args = "#{event.to_json},#{options.to_json}"
flash[:events] ||= []
flash[:events] << json_args
endand
