Answer 1

You can modify save method on your product model

def save(self, *args, **kwargs):
    super().save(*args, **kwargs)
    device = FCMDevice.objects.all()
    device.send_message(title="Title", body="Message", icon=..., data={"test": "test"})

Well, it will send the notification every time the instance is saved (not only when it was added in django admin panel).

You need to use the Django model post_save signals to achieve this. This signal receiver can be placed in the same place where the model is

class FCMDevice(models.Model):
    ...

@receiver(post_save, sender=FCMDevice)
def notify_users(sender, instance, **kwargs):
     # your logic goes here
     # instance is referred to currently inserted row
     pass

You might wanna check post_save signal. From the docs:

Like pre_save, but sent at the end of the save() method.

django-version: 1.7+
