using gem unread with public_activity

I'm not sure this is possible, but given the way you can inject a method into modules, is there a way to inject "acts_as_readable :on => :updated_at" into PublicActivity::Activity?

The issue is this: I want unread to also track the new activities the user has not yet seen, so I first tried it this way.

class Activity < PublicActivity::Activity
  acts_as_readable :on => :updated_at
end

class User < ActiveRecord::Base
  acts_as_reader
end

However I noticed in the record (DB table read_marks) when I do

Activity.mark_as_read! :all, :for => current_user

that the readable_type key is set to 'PublicActivity::Activity' instead of 'Activity'

This is because the Unread gem uses

user.read_marks.build(:readable_id => obj.id, :readable_type => self.base_class.name)

that base_class gives the class closest to ActiveRecord::Base What would be the best option?

1) inject somehow the 'acts_as_readable :on => :updated_at' directly into PublicActivity::Activity

2) fork PublicActivity and check if Unread gem is installed, if so add the line 'acts_as...'

3) fork the Unread gem and ... not sure what I would do here, the first ugly thing that comes to mind would be to check if a class begins with PublicActivity!

And just to define the issue: Since the record's (DB table read_marks) readable type is PublicActivity::Activity and not Activity, my 

Activity.unread_by(current_user).count

never returns the correct count. Using 

PublicActivity::Activity.unread...

would fail since the 'acts_as_readable :on => :updated_at' is in Activity and not PublicActivity::Activity.

UPDATE

I've tried to 'monkey-patch' the Public_Activity plugin but now I'm even more confused as to why it fails, it must be something dumb I'm doing. I added the following file. However the readable_type is still PublicActivity::Activity and my count remains the same after I do

PublicActivity::Activity.mark_as_read! :all, :for => current_user


# config/initializers/activity_unread.rb
PublicActivity::Activity.module_eval do

  acts_as_readable :on => :updated_at

end

UPDATE

AH! It was the readable_type field having a limit of only 20 that was truncating my class name. Now it works after I increased the size.

You can count all activities belonging to the current user using this

<span class='badge'> 
    <%=  PublicActivity::Activity.order("created_at desc").where(owner_id: current_user.follower_ids , owner_type: "User").count %>
</span>

Idea is: whenever user see his public_activity page, create his custom activity in PublicActivities table.

Next time, when user see his page then compare date of that ("publicactivity.visit") activity with all the new activities and show all unread new activities

Not sure if you found the solution, but to get rid of the error (I am using Ruby 1.9.3 & Rails 3.2) change

PublicActivity::Activity.template = YAML.load_file("#{RAILS_ROOT}/config/pba.yml")

to

PublicActivity::Activity.template = YAML.load_file("#{Rails.root}/config/pba.yml")

I created a file called pba_setup and inserted the above line in the initializer folder. Now that cleared up the error when loading, but I still get a missing template error? Hope this helps!
