How deploy a Django app?

I'm very close to finish my django project and I'm worried about the deploy. So far, I have an EC2 instance in AWS and even tough it's "online", it's just the EC2 running "python3 manage.py runserver" all the time.

I know this is not the best way, so I wanted to ask you guys:

\-How should I manage my Media/Static files?

\-How should I manage the DB?

\-How should I keep running the app?

\-How can I keep my code updated with my repo in github?

I'm pretty newbie in this deployment field, so I'll appreciate your help and comments :D

PyCharm docker-compose interpreter in WSL

Hey everyone! New coder here.

Building my first web app, I started out with venv in WSL. That worked great for the first 2 months but I've since brought Celery, Mailpit, Redis, and Flower into the equation, which made it very tedious to manage everything manually, so I learned Docker and dockerized my app (I now love Docker, btw :D).

For development, I use Docker Desktop with the WSL-based engine and everything's fine except that I can't configure the Python interpreter in PyCharm to use docker-compose in WSL. The functionality is there but after hooking it all up, it fails with the following errors:

​

Over the past 3 days, I've tried reinstalling WSL, Docker Desktop, multiple versions of PyCharm Pro, and seemingly anything in between to no avail.

My question is, has anyone successfully managed to use a Python interpreter hooked to a docker-compose in WSL in PyCharm? I really like PyCharm, but without the above, I can't use the debugger, so I'd probably try running the same setup on native Ubuntu on dual-boot or move to VS Code.

What was for you the biggest thing that happened in the Python ecosystem in 2023?

Of course, there was Python 3.12, but I'm not only talking about version releases or libraries but also about projects that got big this year, events, etc...


EDIT : so nobody cared about pandas 2, mojo or python in Excel ?

dotenv or config.json

I know both will work, but is it better to access your environment variables (SECRET_KEY, EMAIL_USERNAME, etc) using load_dotenv() or json.load(config_file)? In both cases the variables are being imported from outside the website's folder structure, but is one approach inherently safer than the other? If so, please explain why.

How to use Flask with SQLAlchemy Core functions?

I found that SQLAlchemy ORM is not what I need, but AFAIK the Flask-SQLAlchemy module is an ORM based one. How can I use SQLAlchemy with Flask without ORM? Is it enough to setup/configure a SQLAlchemy object at the start of app:

db = SQLAlchemy(app)

then get a connection object from it:

conn = db.engine.connect()

and then use it if it was made by the original (non-flask) sqlalchemy?

Flask-login not working after starting program on a different machine? Never matches hash.

I have a program working with Flask-Login for authentication. I have been testing and using it for the last couple of months with no issue with the admin account being able to login and be remembered by the browser.

I now attempt to set up the program from scratch on another machine and I cannot log in even after creating the account.

I have this function:

bcrypt = Bcrypt(app)

def createadminuser(bcryptobj):
password = os.getenv('ADMINPASSWORD')
hashedpw = bcryptobj.generatepasswordhash(password)
if db.session.query(Users).filter(Users.userid == 1).first() is None:
adminuser = Users(
userid=1,
username="admin",
password=hashedpw,
)
db.session.add(adminuser)
db.session.commit()

with app.appcontext():
db.createall('main')
db.createall('config')
createadminuser(bcrypt)

This successfully creates the admin account:

1|admin|$2b$12$3DaNwkdb4rym0r2EMoLR6OCoJj8QpSgcq7gt0yVM9tqGb0HGWNk1a

I have a script to generate the admin password and overwrite the old one if necessary:

if sqlite3 webapp/instance/test.db "SELECT EXISTS(SELECT 1 FROM users WHERE username='admin';"

My first time selling a website.

It's my first time selling a website, how much should I price it?
All this time and I only hosted my projects on free slow services, but since I'm working a full project then I don't where should I host it for the best experience and how much should I charge for it.
The website is a landing page for a startup, and the whole purpose of it is just to view their services.
No payment services, no actual accounts and stuff. Just 2-5 pages max.
I need advice on how much should I charge for it, where to host it, and some details that I may not be aware of. If anyone can help then that'll be great. Thanks already! (I don't know what to flair my post)

PGVector operator does not exist: vector <#> numeric

I am using PGvector with Django. While I usually leverage the PGvector ORM functionality, this usecase requires a complex query which I am running in raw sql as shown below. https://gist.github.com/Thehi198/de053c5bc402046f6e36468642681cfb


I get the output shown below when running django, where pgvector does not seem to recognize a list. I have tried converting to a nparray, and explicitly defining a list. I have also run this query in my Postgres console successfully.

DRF - Why is CSRF token cookie not being set, disappears on page reload, and unable to get cookie?

I'm working on a Django / DFR + SvelteKit project and have been struggling for several days on this :(

I am trying to use Django's session-based auth system and csrf tokens which are stored in cookies.

Problems:

1. When the page first loads, there is no csrf token in the cookies, so for testing purposes I added a button to request one from the server. This does add the cookies to the page.
2. After the csrf token cookie is set, if I refresh the page, the cookie disappears and I have to click the "set csrf cookie" again... No clue why this is happening and have not been able to resolve it..
3. When I make the POST request, the csrf token logged out as undefined - and then the csrf cookie disappears - beyond frustrating and don't understand why this is happening.
4. When I make the request without any csrf token, essentially removing the `'X-CSRFToken': csrfToken` header in the request, the Django DRF view still accepts the post... when I explicitly set `authentication_classes = [SessionAuthentication\]` which should only accept POST requests that have valid csrfs....

Looking for any help that I can get.

Help with Auth Tokens from other APIs

Quick overview of what I'm trying to build: User clicks a link, does an Oauth for API 1 is redirected to an Oauth for API 2 and then that is the last interaction the user has. Afterwards a subscription service from API 1 sends information that a record in API 1 has updated. This triggers calling information from API 1 using it go get information from API 2 and then updating the record on API 1 with information gathered from API 2. I'm fairly new to development, but I have all of this working locally using Flask and session[\] variables to store the tokens and use them when re-authenticating and refreshing.

Now that I am getting ready to actually implement this in the real world and not just my local machine I'm not sure what I need to do in order to store these tokens since there will be no user after they authorize my application with both of the other API's and so I obviously can't get them to click authorize since they won't be actively going to a page when I need to call the APIs. Searching has lead to way too many different

My first large scraping website built using Django

14 months I decided to learn programming. After 10 years as a nurse I needed a change. 3 months ago I built my wife a ecommerce website using Django and learned a ton. Today I launched my first large scraping website using Selenium and BS4. I used redis, celery, and postgres for this project. I use the Appliku SaaS to aide in easy deployment, a Hetzner server, and S3 bucket and CDN for images. I know very little JavaScript so I bought the HTML template off themeforest for like $12. I then manipulated the HTML and inserted the Django portions. I also use HTMX to decrease page reloads. HTMX is used mostly when submitting forms. I had to learn Docker due to needing a customized Dockerfile for selenium. At first I was using Playwright, but could not figure out how to get Playwright to work with the Dockerfile, so I switched to Selenium. One thing I noticed on my ecomm website was the large amount of bots that would sign up to site and send messages through contact form so I added ReCaptcha to help prevent this. I would suggest adding ReCaptcha as it's fairly easy to implement. I built
