Ahoy 2 Upgrade

Ahoy 2.0 brings a number of exciting changes:

• jQuery is no longer required
• Uses navigator.sendBeacon by default in supported browsers
• Simpler interface for data stores

How to Upgrade

Update your Gemfile:

gem 'ahoy_matey', '~> 2'

And run:

bundle update ahoy_matey

Add to config/initializers/ahoy.rb:

Ahoy.api = true
Ahoy.server_side_visits = false

You can also try the new Ahoy.server_side_visits = :when_needed to automatically create visits server-side when needed for events and visitable.

If you use visitable, add class_name to each instance:

visitable class_name: "Visit"

Then follow the instructions for your data store.

• ActiveRecordStore
• MongoidStore

Data Stores

ActiveRecordTokenStore

In config/initializers/ahoy.rb, replace Ahoy::Store with:

class Ahoy::Store < Ahoy::DatabaseStore
  def visit_model
    Visit
  end
end

ActiveRecordStore

Add uuidtools to your Gemfile.

In config/initializers/ahoy.rb, replace Ahoy::Store with:

class Ahoy::Store < Ahoy::DatabaseStore
  def track_visit(data)
    data[:id] = ensure_uuid(data.delete(:visit_token))
    data[:visitor_id] = ensure_uuid(data.delete(:visitor_token))
    super(data)
  end

  def track_event(data)
    data[:id] = ensure_uuid(data.delete(:event_id))
    super(data)
  end

  def visit
    @visit ||= visit_model.find_by(id: ensure_uuid(ahoy.visit_token)) if ahoy.visit_token
  end

  def visit_model
    Visit
  end

  UUID_NAMESPACE = UUIDTools::UUID.parse("a82ae811-5011-45ab-a728-569df7499c5f")

  def ensure_uuid(id)
    UUIDTools::UUID.parse(id).to_s
  rescue
    UUIDTools::UUID.sha1_create(UUID_NAMESPACE, id).to_s
  end
end

MongoidStore

In config/initializers/ahoy.rb, replace Ahoy::Store with:

class Ahoy::Store < Ahoy::DatabaseStore
  def track_visit(data)
    data[:_id] = binary_uuid(data.delete(:visit_token))
    data[:visitor_id] = binary_uuid(data.delete(:visitor_token))
    super(data)
  end

  def track_event(data)
    data[:_id] = binary_uuid(data.delete(:event_id))
    super(data)
  end

  def geocode(data)
    visit_model.where(id: binary_uuid(ahoy.visit_token)).find_one_and_update({"$set": data}, {upsert: true})
  end

  def visit
    @visit ||= visit_model.where(id: binary_uuid(ahoy.visit_token)).first if ahoy.visit_token
  end

  def visit_model
    Visit
  end

  def binary_uuid(token)
    token = token.delete("-")
    if defined?(::BSON)
      ::BSON::Binary.new(token, :uuid)
    elsif defined?(::Moped::BSON)
      ::Moped::BSON::Binary.new(:uuid, token)
    else
      token
    end
  end
end

Throttling

Throttling was removed due to limited practical usefulness. See instructions for adding it back if you need it.

Options

• The mount option was renamed to api
• The track_visits_immediately option was renamed to server_side_visits
