Rails - May 2011 - Constructing an array of stuff (to send multiple apple push notifications)

I''m using this gem https://github.com/justintv/APNS to send push
notifications to an iPhone app and amazingly it works for single
notifications, such that I can do...

APNS.send_notification(Device.first.device_token,''test
message'')

Works great...

Now it should be a simple task (as per the docs to send multiple
notifications)

Gem says like this...

device_token = ''123abc456def''
n1 = [device_token, :aps => { :alert => ''Hello...'',
:badge => 1, :sound
=> ''default'' }
n2 = [device_token, :aps => { :alert => ''... iPhone!'',
:badge => 1,
:sound => ''default'' }]
APNS.send_notifications([n1, n2])

#####

for me it''s slightly different, I wish to loop through each device in
my
db and then send the same message to them all...it''s something like
this
but it''s clearly not quite right... can''t get the :aps =>
thing to work
out.

I think I need something like this on my Device model, but it''s not
right - please help correct it, would greatly appreciate.



  def self.push_message_to_all(message)
    devices = self.all
    notifications = []
    devices.each do |device|
      notifications << [device.device_token,message]
    end

    APNS.send_notifications(notifications)

  end

Have you tried that?  It doesn''t look like valid ruby to me (even with
the missing ] on the end of n1)

Once you have got the manual example above working the use ruby-debug
to break in here and have a look at notifications and see if it is of
the same form as if you break into the manual test and look at it
there.

Thanks Colin, I''ll give that a spin.

The example code in the gem does seem odd.
