How to host 2 server in one Azure App Service?
I'm having a web app which is based on ReactJS (Frontend) + Django (Backend), I've integrated ReactJS with Django and make it as single server based application. I have 1 more server which is based on Express JS separately. I'm trying to host my web application in Azure app service and publisher is Docker Container. So, I am hosting React + Django based web app in 1 app services it is successfully getting hosted along with the SSL certificates. Now, I am trying to host Express JS in same web app in which I hosted React + Django based web app since Django + React is running on port 80 . I am not able to host Express JS in same app service and if I am trying to host Express JS on separate app service, it is getting hosted but now domain is changed or there need to be some subdomain which I don't want. PROBLEM: I want to host both Django+React server and Express JS server in same app service in which my main web-app is hosted. Any help or any leads are highly appreciated -

How to view the progress of the django app in the browser
I want the process of the app to be dispayed in the browser so that suers know how much it has been done. However, in django, the view receives the event that occurred in the template(browser) and passes it back to the template, so I don't know how to pass it from the view itself to the template. For example, when the user clicks a button, a total of 3 fuctions are executed in trun. At this time, I want to show 'End of function1, start of function 2' when fuction 1 ends. it same way for fuction2,3. I'm not sure if I should do this in view or make it in JS. The functions runs in python. I'm not familiar with django, so this might be a very rudimentary question. Please Help me :) The fuctions are performed in the view in order, and when each function is completed, render or redirect is perfomed to template. but it is expressed only at the first fuction and does not proceed any further. -

Issue with exited containers named "django-run-{uuid}" when switching interpreters in PyCharm
I have connected PyCharm with a docker-compose container for debugging multiple services. However, changing the interpreter creates exited containers named "django-run-{uuid}". I have investigated and it doesn't seem to be a persistent issue with PyCharm. There are no syntax problems in the Dockerfile or docker-compose configuration files either. I'm curious to know if this is a natural occurrence during the interpreter refresh process in PyCharm or if it is an artificially induced problem. If it is artificially induced, I would like to know where to look for the source of the issue. -

Problems with Python installation and Pycharm virtual environments
I've been using PyCharm for a while now, when I first started using it python 3.7 was the latest release so I used that, everything worked fine (~8 different projects). However, the latest version of Django requires python 3.8 or later so I finally updated and installed 3.11. I'm having some problems setting up my Pycharm projects with python 3.11 (my system can't import Django even though it's installed, I think it stems from the project not being in a venv but I've tried to add it into one).I've installed python 3.11 in the default location, the same place python 3.7 was installed but when I choose a python interpreter (screenshot below) many of them are invalid. I also notice that many of my other projects (FaceComparison as an example) are using a python 3.7 that itself is within a virtual environment, within the Scripts folder by the looks of it. Should I have installed python 3.11 in a virtual environment? Whenever I try and set up a new project and use a python 3.11 interpreter, a) it's got (DjangoTesting) in it - not sure why? and it also isn't in a virtual environment. I've read many questions about Pycharm, … -

How to add additional user data upon first social sign in with django-allauth?
In Django REST framework, when a user signs in via a social account, say Google, I post to 127.0.0.1/accounts/google with an 'access_token' from the frontend client. 'django-allauth' then pulls data like first name, last name, email from Google, and even creates a username. However, I want to enforce two additional required fields dob (date of birth) and gender, and allow for a custom username when the user first signs in via a social account. How can I POST to 127.0.0.1/accounts/google with additional data? Or are there other ways to do so? I tried changing allauth.socialaccounts.form.SignUpForm, but it doesn't seem to work with Django REST framework. -

Django Async (uvicorn) is very slow
I have a boilerplate app and was playing around with Django Async(planning to add some GraphQL + subscriptions) and made a benchmark that shocked me. Gunicorn with async worker uvicorn is much more slower than gthread. Async Code: async def my_async_view(request): return JsonResponse( {"async accounts": "Test"}, status=200, ) Gunicorn Async command: gunicorn --worker-class uvicorn.workers.UvicornWorker banking_api.asgi --workers=8 --threads=2 Sync Code def my_sync_view(request): return JsonResponse( {"sync accounts": "Test"}, status=200, ) Gunicorn Sync command: gunicorn banking_api.wsgi --workers=8 --threads=2 Benchmark results: Async: Running 30s test @ http://localhost:8000/test/ 12 threads and 50 connections Thread Stats Avg Stdev Max +/- Stdev Latency 57.72ms 75.82ms 1.08s 97.25% Req/Sec 81.90 44.42 232.00 81.61% 29007 requests in 30.05s, 8.08MB read Requests/sec: 965.41 Sync: Running 30s test @ http://localhost:8000/test/ 12 threads and 50 connections Thread Stats Avg Stdev Max +/- Stdev Latency 24.26ms 44.37ms 865.76ms 92.37% Req/Sec 281.56 146.56 0.89k 66.32% 100051 requests in 30.08s, 30.25MB read Requests/sec: 3326.37 What is happening? Why the difference of Requests/sec of 3326.37 (sync) vs 965.41 (async) ? Am I doing something wrong here? Thanks -
