Constructing an array of stuff (to send multiple apple push notifications)

Rails
1

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

Any ideas?

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

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

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.
