Overriding restore method in Django
I would like to run a piece of code after object is restored in Django but not have it run every time save() is runed. How can I override restoration method in Django?

Celery workers not working with RabbitMQ after upgrade
Problem description I have a working django application using Celery along with Mongo and RMQ (3.7.17-management-alpine) The application runs on kubernetes cluster The application works fine in general But when I upgrade Celery (3.1.25) and Kombu (3.0.37) to Celery (4.1.0) and Kombu (4.1.0), I face following issue: Celery worker pods come up but do not receive the tasks I have verified that RMQ receives the messages needed to run tasks in celery workers There is no error in RMQ or celery worker pod In fact, celery pod mentions that it is connected to RMQ Strangely, when I restart the RMQ pod after Celery worker pod comes up things become fine I am able to run the new tasks in celery workers after I restart RMQ pod So I guess something happened wrt Celery/Kombu/RMQ after upgrade to 4.1.0 The code works fine with older version of Celery and Kombu. Can someone please help me wrt this? -

Can't reach this page took too long to respond. Django, Gunicorn and Nginx. This is until I reboot my instance manually
I hosted my Django website on AWS Lightsail instance on an Ubuntu server with Nginx and Gunicorn. Everything works fine when it is running super fast everything works great, but sometimes it stops running, I can't reach the website only until I restart my lightsail instance manually. This I think happens in the interval of 24 hours (probably). I don't know why it is happening? what causing it? Someone suggested to me that it's something related to the server itself, Server goes to sleep, or something but when any request comes it can't respond to that. If there is anything that you want to see to get more info plz comment I'll add that. I don't have much idea about this problem, I'll appreciate your help. -
How to send kwargs for form MultipleChoiceField in POST view unit test
