I use faye and private pub as push server. I need to update user's status to online when he subscribes to channel.
I have forked private_pub gem and changed some code, my application sends user_id, but I don't know how to find user and update his status, because subscription event fires in the gem.
module PrivatePub
# This class is an extension for the Faye::RackAdapter.
# It is used inside of PrivatePub.faye_app.
class FayeExtension
def incoming(message, callback)
p "user_id = #{message['ext']['user_id']}"
if message["channel"] == "/meta/subscribe"
authenticate_subscribe(message)
# user = User.find(message['ext']['user_id'])
# user.status = 'online'
# user.save
elsif message["channel"] !~ %r{^/meta/}
authenticate_publish(message)
end
callback.call(message)
end
end
end
I can get user_id but I can't use User model in a gem. Which is the best way to do it?
Try to add environment to private_pub.rb. For ex.
