Django Instapush (Push Notifications for Django)

---

This django app can be used to send gcm and apns push notifications to mobile devices. The app implements models for sql based databases and monogoengine documents. You can specify the settings to either use a sql based model or a mongoengine model to store your device data.

##Models

SQL Models

There are 3 sql models to store the device information BaseDevice, GCMDevice and APNSDevice. Both GCMDevice and APNSDevice extends from the BaseDevice model. You can either use these models to store your device information or can create a custom model extending from the BaseDevice model.

Using builtin GCM model

---

from instapush.models.base import BaseDevice, GCMDevice, APNSDevice

device_id = preferences.get_unique_id()
reg_id = preferences.get_registration_id()
user = preferences.get_user()

device = GCMDevice.objects.create(registration_id=reg_id, device_id=device_id, owner=user)

Using builtin APNS model

---

from instapush.models.base import BaseDevice, GCMDevice, APNSDevice

device_id = preferences.get_unique_id()
reg_id = preferences.get_registration_id()
user = preferences.get_user()

device = APNSDevice.objects.create(registration_id=reg_id, device_id=device_id, owner=user)

Using a custom model

---

from instapush.models.base import BaseDevice, GCMDevice, APNSDevice

device_id = preferences.get_unique_id()
reg_id = preferences.get_registration_id()
company = preferences.get_company()

#custom/models.py
class CompanyGCMDevice(BaseDevice):
    regid = models.CharField(max_length=255)
    custom_device_attribute = models.CharField(255)

device = CompanyGCMDevice.objects.create(registration_id=reg_id, device_id=device_id, owner=company)

Mongoengine Models

This app also support mongoengine Documents as django models. It implements the similar 3 models that can be used to send push notifications, in case your project uses mongoengine to define the models. The models would work the same as shown above in the sql models section. The only change is that you'd need to import it from the mondels.mongo module instead of models.base

from instapush.models.mongo import BaseDevice, GCMDevice, APNSDevice

##Push Notifications

Instapush django push notifications support both GCM and APNS. The device object saved in the models have a method send_message attribute to send the push notifications.

Sending Exclusive GCM/APNS push notification to a device

---

To send an exclusive method to a particular device you'll need to fetch the device that you'd want to send a push notification to and call the send_message on the device object to exclusively send a notification to that device.

from instapush.models.mongo import APNSDevice, GCMDevice

device = GCMDevice.objects.get(owner=request.user)
device.send_message({"type": "notify", "message": "You've a new notification"})


device = APNSDevice.objects.get(owner=request.user)
device.send_message({"type": "notify", "message": "You've a new notification"})

Sending bulk GCM/APNS push notification to multiple devices

---

Instapush allows you to send bulk gcm and apns push notifications to multiple devices at a time. It implements 2 methods gcm_send_bulk_message and apns_send_bulk_message to send notification to android and ios devices respectively. Both these methods accept 2 arguments:

1. List of device registration ids to send messages to
2. The message data

from apps.communication.instapush.libs import apns, gcm
from apps.communication.instapush.models.mongo import APNSDevice, GCMDevice

gcm_devices = GCMDevice.objects.filter(owner__in=[user1, user2, user3])
apns_devices = APNSDevice.objects.filter(owner__in=[user4, user5, user6])

gcm_registration_ids = [device.registration_id for device in gcm_devices]
apns_registration_ids = [device.registration_id for device in apns_devices]

## Send bulk GCM notifications
gcm.gcm_send_bulk_message(registration_ids, {"type": "3", "message": "You have a notification"})

## Send bulk APNS notifications
apns.apns_send_bulk_message(registration_ids, {"type": "3", "message": "You have a notification"})

##Settings

Instapush settings should be a dictionary object named INSTAPUSH_SETTINGS defined in your django settings. The generic settings to be used for both gcm and apns notifications are directly a key:value pair within the INSTAPUSH_SETTINGS. For settings specific to gcm and apns the key:value pair should be defined under GCM_SETTINGS and APNS_SETTINGS keys as a dictionary object which are defined under INSTAPUSH_SETTINGS.
