Question

I have my app_key, key, and secret in my ApplicationController

my PusherController:

  def auth
    if current_user
      auth = Pusher[params[:channel_name]].authenticate(params[:socket_id],
        :user_id => current_user.id, # => required
        :user_info => { # => optional
          :name => current_user.name,
          :email => current_user.email
        }
      )
      render :json => auth
    else
      render :text => "Not authorized", :status => '403'
    end
  end

My js

var pusher = new Pusher("key");
Pusher.channel_auth_endpoint = "/pusher/auth";
Pusher.channel_auth_transport = 'json';

channel = pusher.subscribe("presence-content_editing");

I’m pretty sure I followed the inscrutions http://pusher.com/docs/presence-1.6

Nwo I”m just confused as to why I get this error

this is the error :
Uncaught TypeError: Cannot call method 'scopedTo' of undefined

Remove these two lines:

Pusher.channel_auth_endpoint = "/pusher/auth";
Pusher.channel_auth_transport = 'json';
