Connecting an internet-facing Django web app (served with Gunicorn) with a non-internet-facing local application to be used by the Django web app
Use case of the internal app: take in a list of words (200-300 words), perform some analysis on them and return large tuples of data, anywhere from 5-10 tuples per word. The Django application will block waiting for the results of the internal app to serve the webpages that needs the word analyses. The reason I want to separate them is because the internal app uses a lot of memory, and integrating the word-analysis (i.e. the task of the internal app) into the Django app will cause high memory usage because of gunicorn forking multiple workers. The internal app uses about 1GB of memory once loaded, but is not compute-intense. Now, assuming I want to host the Django web app and the internal app on the same server, what comes to my mind is to use a flask application for the internal app, and put it behind gunicorn. So two questions: Is there a better way to accomplish this? Is using gunicorn the right way to go for the internal app? -
Django project on AWS EC2, what should put in ALLOWED_HOSTS?
Problem I deployed my project on AWS EC2 with docker. When ALLOWED_HOSTS is set as '*', the web site works fine, it looks just what it should be.

Django Redirects + FeinCMS - URL variable
I am using an older server with Python 2.7 and Django 1.11.7 with FeinCMS as the CMS. If I wanted to redirect any incoming URL from a request that had mixed casing to the proper URL in all lowercase letters, how would I go about doing that? Is there a way to edit the incoming request and, if the page is matched but it's detected not to be a match to the lowercase URL, it will do a redirect to the page? I have the original function below and one that I edited and made enough progress to get the proper page to show up, but the URL in the address bar still has the mixed casing. Any help would be greatly appreciated. Original Function: def dispatch(self, request, *args, **kwargs): try: return super(Handler, self).dispatch(request, *args, **kwargs) except Http404 as e: if settings.FEINCMS_CMS_404_PAGE is not None: logger.info( "Http404 raised for '%s', attempting redirect to" " FEINCMS_CMS_404_PAGE", args[0]) try: # Fudge environment so that we end up resolving the right # page. # Note: request.path is used by the page redirect processor # to determine if the redirect can be taken, must be == to # page url. # Also clear out … -

How to check if user has passed the form?
I have a Person class in models.py, a class has a code field (charfield). A user should enter code on the page with the form where he will enter the code user will be allowed to enter the site.

Bad Gateway python-telegram-bot with webhook and Nginx
I'm trying to set up a webhook with python-telegram-bot and Nginx. I am faced with a problem, my bot doesn't get messages from telegram. I also tried to make GET/POST queries from the postman and I always get a "502 Bad Gateway" error. I also launched the netstat to monitor port 5000 where my telegram bot connects but it is always empty. It seems like webhook doesn't launch at all.

How to give specific users specific persmissions to view and edit Specific Areas in Django admin
I'm making a django website whose admin page looks like this I want users(The content writer) to access only the Main Area(Events, Formats, Organisers) and not the whole thing. I haven't made any such user as Content Writer as of now. What are the permissions that should be given to that user. Should I make Groups for users(since there are basically 3 types of users as of now, i.e., Admin(Full Access), Content Writer(Limited Access), Basic Users(No access)) or should I just add one/two more variable(s) in my custom user model so that that user can access only the main area of the admin site.

How to manage devices on docker-compose automatically?

In this case, it works if 10 cameras are connected to the local PC, but cause errors if I take out any of them because the container can not map some of the cameras listed up. So for now, I need to comment out them depending on the number of cameras connected to the local. Is there any solutions for this case so that I do not have to comment out like I mentioned above? version: '3' web: build: . devices: # Here is the problem!!! - '/dev/video0:/dev/video0:mwr' - '/dev/video1:/dev/video1:mwr' - '/dev/video2:/dev/video2:mwr' - '/dev/video3:/dev/video3:mwr' - '/dev/video4:/dev/video4:mwr' - '/dev/video5:/dev/video5:mwr' - '/dev/video6:/dev/video6:mwr' - '/dev/video7:/dev/video7:mwr' - '/dev/video8:/dev/video8:mwr' - '/dev/video9:/dev/video9:mwr' ports: - '8000:8000' volumes: - '.:/code' tty: true stdin_open: true command: > bash -c 'python manage.py makemigrations && python manage.py migrate && python manage.py runserver 0.0.0.0:8000' Thank you in advance for my very first question in stack overflow! -
Why doesn’t Heroku add or remove database tables after initial launch for django app
So I punched my Django app on heroku and every thing has been going fine for about 3 weeks now. Now I want to update my models and add more fields but when I do so, it doesn’t seem to update the database. I run the following: heroku run python manage.pu makemigrations and the same for migrate. Every run through fine but the migrations doesn’t really go through although it says the fields have been altered. Anyone know how to update models for django app on heroku after initial launch?
