Disable tracking for rails ahoy_email

Question

I've recently upgraded to ahoy_email version 2.0.3 from 1.1.1 and i've been refactoring my code to work with the latest version but i'm having a bit of an issue with a piece of functionality i used to have. The problem is the following:

I want to be able to disable tracking for some of the mails that get sent.

With the changes made to ahoy_email in version 2.0.0, all of the class methods that set the ahoy_settings perform add a before_action which merges the options set from on of the three methods, i.e. track_clicks, has_history and utm_params, so since the options only get merged in a before_action i can't do something like the following:

class DigestMailer < ActionMailer::Base
  has_history user: -> { @recipient }, extra: -> { {digest_message_id: @digest_message.id} }
  track_clicks campaign: "digest"

  def digest(digest_message, user, **options)
    @recipient = user
    @digest_message = digest_message
    self.class.has_history options
    ....
  end
end

DigestMailer.digest(DigestMessage.first, User.first, click: false, message: false).deliver_now

The options i've set in the digest action wouldn't actually get merged, since they are supposed to get merged before calling the digest action

What i could do tho, is the following:


class DigestMailer < ActionMailer::Base
  has_history user: -> { @recipient }, extra: -> { {digest_message_id: @digest_message.id} }
  track_clicks campaign: "digest"

  def digest digest_message, user, **options
    @recipient = user
    @digest_message = digest_message
    self.ahoy_options = AhoyEmail.default_options.merge(options)
  end
end

DigestMailer.digest(DigestMessage.first, User.first, click: false, message: false).deliver_now

This works, because i'm overriding the ahoy_options attribute after the before_action callback gets called and before the after_action callbacks get called and it works.

So my question is: Is this the right way to go about this?

Because this commit, from 3 years ago, clearly says:

Keep old method of disabling tracking

But it's nowhere to be found in the documentation.

To anyone who runs into the same problem, i've found the solution and it consists of two things:

Using a parametrized mailer and using the :if option of the track_clicks, has_history and utm_params. The code can be rewritten as the following:

class DigestMailer < ActionMailer::Base
  has_history(
    user: -> { params[:recipient] },
    extra: -> { {digest_message_id: params[:digest_message].id} },
    if: -> { params[:options].try(:fetch, :message) != false }
  )

  track_clicks(
    campaign: "digest",
    if: -> { params[:options].try(:fetch, :track_clicks) != false }
  )

  def digest
    recipient = params[:recipient]
    digest_message = params[:digest_message]

    Rails.logger.info "Sending digest to #{recipient} with email #{recipient.data.email}"
    internal_send_digest_message(digest_message.title)
  end
end

DigestMailer.with(digest_message:DigestMessage.first, recipient: User.first, options: {track_clicks: false, message: false}).deliver_now

And it will work as expected.
