show only related notifications for specific user?

[vmcilwain]

I'm sorry if this is the wrong place to post this but I didn't see another place in the documentation. I am curious if there is a way to show only gritter notifications related to a specific user? An example I can think of is if I am sending a message to another user, I would like only for that user to get a gritter notification.

Can this be done?

I'm not really sure what you're trying to do. You want to show one user a gritter notification when he/she receives a message? That should be possible with the add_gritter helper. You can change the message depending on the user it's being sent to (presumably via the current_user method). Not really sure if that's what you're asking. If not, please explain yourself further.

BTW, I'm going on vacation in about 7 hours. So if you leave a reply after 7 hours, I won't be able to reply until I'm back.

Yes that is exactly what I want. I want the person I send a message to to get a grittier notification in their view that tells them that I sent a message. I do have a current_user method but couldn't figure out how to make this happen. I will take a closer look at the add grittier message. I guess the problem I couldn't figure out is how to target the user with grittier. How would I tell grittier to show this to the given user.

Enjoy your vacation :)

What you want to do is have some kind of Controller action that's repeatedly being called by a JavaScript timer. Within this action you check if the user has new messages. When there's a new message, you just send JavaScript back to the browser showing a Gritter notification. Here's an example:

# app/assets/javascripts/application.js
$(function(){
  setInterval(function(){
    $.getScript("/messages/check");
  }, 2000);
});

# config/routes.rb
get "messages/check" => "messages#check"

# app/controllers/messages_controller.rb
class MessagesController < ApplicationController
  def check
    render :nothing => true unless current_user.new_messages?
  end
end

# app/views/messages/check.js.erb
<%= add_gritter("There's a new message!") %>

Inside the User Model you can have a new_messages? method that checks for new messages. When a user sends a message you make sure this new_messages? method returns true for the receiving user. When this is the case, the getScript() jQuery function receives '/messages/check' with the messages/check.js.erb view. It's probably not the best example, but it should work. Hope it helps. :)
