Hello all,
I am currently working on a push notifications library for Django
(https://github.com/rakanalh/django-pushy). The current implementation
provides the ability to send a push notification to all registered device
keys (Android and iOS).
The current use-case for the library is doing the following:
from pushy.utils import send_push_notification
send_push_notification('YOUR TITLE', 'YOUR BODY')
This would basically insert the push notification into the database and
trigger celery to distribute *ALL device keys* into subtasks where each
subtask sends to a certain group (0-5000, 5000-10,000 .. etc) of keys. One
of the features i am aiming to implement for the library is the ability to
filter the list of devices the designated push notification is to be sent
to. So instead of having this line of code
<https://github.com/rakanalh/django-pushy/blob/master/pushy/tasks/__init__.py#L21>,
which basically fetches all device keys... i would like to be able to let
the user filter these devices.
The only option that comes to mind is to add **kwargs to
send_push_notification so that the user can supply the device query filter
params, which then get stored in the database to be restored in the celery
task to filter the list of devices. I currently have no idea if this would
work because i am thinking about the possibility of the user passing
user=user_object or some_foreign_key=instance. That would lead me to lots
of unnecessary query handling code. The question here is: can i turn a
queryset into a string and restore it back into a queryset object?
Otherwise, what are my options? thoughts on this design issue are
appreciated.
Thanks,
Rakan
