Re: Django channels with python background tasks

Another idea: create a Django management command that does the telnet stuff and just run that periodically via Cron. You can always move to channels or celery later.

In addition to websockets, channels can be used to run background tasks that could take a long time for example a telnet connection. You can Google Django channels background tasks.

An alternative to channels for background tasks is celery.

Hi Jaiswal,

I'm afraid that I can't give detailed help about what your best options are or walk you through how to do it - that's something you'll have to research and decide on yourself. Channels allows you to do low-latency communictation between Django back-ends and JavaScript, but anything you can do with it can also be done slower using a polling API connection.

My recommendation would be to start simple - doing it using an API that you poll every few seconds - and then once you have that figured out, look at how you could improve it using WebSockets and channels.

Hi,

I am writing a python based application(CLI Back End) which does telnet to some network components and gets some data. It saves the data in sqlite db.

For this application I am writing Django based frond end. Which will start the CLI app and monitor it. For communication between the CLI App and django I am not able to decide what to use. I read somewhere on net that django channels can be used in this problem.

I have no idea about what django channel is and what it does. Can some one please help me in this I need to come up with a tool for this CLI and django communication ASAP.

Thanks in advance!

Regards, Jaiswal.
