mixpanel_tracker

Provides ability to track Mixpanel events in Rails. Events can be tracked from controllers - and no funnel will break.

Add to your Gemfile

gem 'mixpanel_tracker'

And bundle it

$ bundle

Then, run the generator

$ rails generate mixpanel_tracker YOUR_ACCESS_TOKEN

This will generate initializer mixpanel_tracker.rb.

If you omit YOUR_ACCESS_TOKEN, initializer will try to fetch access token from environment variable ENV['MIXPANEL_ACCESS_TOKEN'].

Place this in your layout before the closing </head> tag:

<%= include_mixpanel %>

Track events in needed places in your controllers:

# landing_controller.rb
def index
  mixpanel.track 'User arrived'
end

You can supply additional data to events:

# orders_controller.rb
def create
  if @order.save
    mixpanel.track 'Order created', items_count: @order.items.count
  end
end

By default, mixpanel_tracker will fetch utm params and register them in events

# mixpanel_tracker.rb
config.register_utm_params = true

You may want to not track events in your development or test environment

# mixpanel_tracker.rb
if Rails.env.test? or Rails.env.development?
  config.enabled = false
end
