Number of unread notifications

Question

I use the public_activity gem to create a notification list for users. Using this post as a link, I try to save the number of notifications that the user has not read. When the user clicks to see the notifications that they have, I want the account to return to zero. The solution to the above question is to create a class method as follows:

def self.unread
where(:read => false)
end

and then put this in the view:

user.notifications.unread.update_all(:read => true)

My controller is as follows:

def notifications
@activities = PublicActivity::Activity.order("created_at desc").where(recipient_id: current_user.id)
end

def self.unread
where(:read => false)
end

and my view is as follows:

<% @activities.each do |activity| %>    
<%= render_activity activity %> 
<% end %>

My question is: where to add:

.update_all(:read => true)

in the view and how can I get unread.count.

Answer 1

def notifications
   @activities = PublicActivity::Activity.order("created_at desc").where(recipient_id: current_user.id)
