I am currently using the gem 'Public Activity', and in the view I have a users activity filtered to only show that user the activities that apply to them, such as 'John Smith commented on your post'. However, I would like to add notifications to this, like facebook or twitter, where a badge shows a number, and when you see the feed the badge disappears.
I have found a gem called Unread which looks ideal, except it requires adding acts_as_readable :on => :created_at to your model, and as I'm using the public_activity gem the class is not accessible to add this.
Is it possible to inject the code the unread gem requires, into the PublicActivity:Activity class?

To anyone that may find this in future, i implemented a completely different system by data modelling my own notifications. Rather than using public activity and unread, I made a new model called notifications. This had the columns:
recipient:integer
sender:integer
post_id:integer
type:string
read:boolean
Then, whenever I had a user comment or like etc, I built a new notification in the controller, passing in the following information:
recipient = @post.user.id
sender = current_user.id
post_id = @post.id
type = "comment" # like, or comment etc
read = false # read is false by default
In the navigation bar I simply added a badge that counted the current_users unread notifications, based on an application controller variable.
@unreadnotifications = current_user.notifications.where(read: false)
<% if @unreadnotifications.count != 0 %>
(<%= @unreadnotifications.count %>)
<% end %>
Then, in the notifications controller I had it run a mark_as_read action on the view. This then set the notification count back to 0.
before_action :mark_as_read
def mark_as_read
@unread = current_user.notifications.where(read: false)
@unread.each do |unread|
unread.update_attribute(:read, true)
end
end
