Workaround ALLOWED_HOSTS for a specific route for startup probe?

I am deploying a Django app to a kubernetes cluster. I want it to have a startup probe, which will basically just be a view that checks the database connection and returns a 200 response.

I'm having trouble because kubernetes will make a request directly to the pod IP with the pods hostname. Additionally, the kubernetes config is kind of out of my hands. I'd rather solve the problem by having a looser Django view than monkeying with the infrastructure code.

Is there a way for a single route / view to ignore the hosts whitelist?

Count the Comment ID over again when created in different Post

Hello!
I would like to know if it possible and if it is, how make the ID of the Comment to start to count over again when created in a different Post.
Thank you!

Can you (developers who've worked professionally with Djano) share a Django project Dockerfile and docker-compose files with what you consider best practices?

It'd be helpful for beginners like myself. I'm just starting out and I read conflicting opinions online about things like whether to include a python virtual environment within Docker or not, as well as about whether to create a new non-root user within the Docker environment or to leave it as root.

I'm also not sure about how to handle environment variables. Do I include them in an .env file and add it to .dockerignore and to .gitignore or do I export them to the system's shell and forgo the .env file?

The samples I've found online describe themselves as quick start guides which leaves me unsure about points like what I've mentioned above. My project will include Django (DRF), Postgres, Celery, and Redis.

How do I debug a exit-code failure for the specific service for my app?

I'm trying to run a Flask app through Apache and eventually host using EC2. When I run

systemctl list-units --type=service

I see that the unit for this specific app, "SITENAME.service" has failed.

When I run

sudo systemctl status SITENAME.service

I get an error saying:

Loaded: loaded (/etc/systemd/system/SITENAMEenv.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Sun 2023-01-01 21:26:25 UTC; 1min 1s ago Process: 787 ExecStart=/home/ubuntu/SITENAME/SITENAMEenv/bin/uwsgi --ini SITENAMEenv.ini (code=exited, status=1/FAILURE) Main PID: 787 (code=exited, status=1/FAILURE) Jan 01 21:26:25 ip-172-31-88-10 systemd1: SITENAME.service: Main process exited, code=exited, status=1/FAILURE Jan 01 21:26:25 ip-172-31-88-10 systemd1: SITENAME.service: Failed with result 'exit-code'.

Where can I get more information on this failure? I can't tell if this is a python issue in the actual application code, or something else.

Nesting Blueprints with Blueprint.registerblueprint() fails

Even though the [Flask Docs](https://flask.palletsprojects.com/en/2.2.x/api/#flask.Blueprint.registerblueprint) state that a Blueprint can register further blueprints, I get the following error:

>AttributeError: 'Blueprint' object has no attribute 'register_blueprint'

Does someone know how I can achieve nesting blueprints?

One to one relationship between user and another table.

I want to create another table that we'll call profile to put additional information about the user. I want to automatically create a profile for every user that will be created. That profile will, obviously, be attached to the user. My problem is I have almost no idea how to do that. I've heard that you could do it with signals but I have a feeling there is another, simpler way.

Should you always use DRF when using Django as a backend for mobile apps?

I'm familiar building web apps with Django. I'm currently building a iOS app in Xcode (my first time building a mobile app) and since I know Django very well, I figured it makes sense to use Django as the backend for the iOS app.

I never had the need to use DRF (Django REST Framework) and never understood its uses when building web apps in Django. I just use javascript's Fetch API and ajax calls worked just fine.

After doing some research on using Django as a backend for mobile apps, it seems the general consensus is to use DRF to help build APIs for the mobile app. But I had some questions:

1. How advantageous is it to use DRF when using Django as a backend for iOS apps? Can't the iOS app just make a direct ajax call to a URL on the django server to get/post data?
2. Will using DRF cut down on development time? I'm not familiar with DRF so I will need to learn it first

2,000 free sign ups available for the "Automate the Boring Stuff with Python" online course. (Jan 2023)

If you want to learn to code, I've released 2,000 free sign ups for my course following my Automate the Boring Stuff with Python book (each has 1,000 sign ups, use the other one if one is sold out):

https://udemy.com/course/automate/?couponCode=JAN2023FREE

https://udemy.com/course/automate/?couponCode=JAN2023FREE2

Udemy has changed their promo code and severely limited the number of sign ups I can provide each month, so only sign up if you are reasonably certain you can eventually finish the course. The first 15 of the course's 50 videos are free on YouTube if you want to preview them.

YOU CAN ALSO WATCH THE VIDEOS WITHOUT SIGNING UP FOR THE COURSE. All of the videos on the course webpage have "preview" turned on. Scroll down to find and click "Expand All Sections" and then click the preview link. You won't have access to the forums and other materials, but you can watch the videos.

NOTE: Be sure to BUY the course for $0, and not sign up for Udemy's subscription plan. The subscription plan is free for the first seven days and then they charge you. It's selected by default. If you are on a laptop and can't click the BUY checkbox, try shrinking the browser window. Some have reported

I am still making a video editor in Python. I am still crazy. Please help me(really).

# IF YOU ARE INTERESTED IN WORKING ON THIS PROJECT, ADD ME ON DISCORD Relt#4423

So it has been some time. The project has evolved countless of times, but i finally came up with a road forward.

# What? What editor?

I am making a video editor in Python and its called CZEditor (reason for name is a story LITERALLY TOO LONG TO EXPLAIN WITHOUT CONTEXT. it involves inside jokes, niche communities, and kids being in these niche communities, being cringy as ever). It will be free, open source, yadda yadda, you've heard this before.

Luckily, i got some stuff you have NOT heard before.Mainly:

CZEditor uses "keyframes" instead of clips for sequencing media. Clips are too clunky and take up space. While they might look nice, they are a pain to use. We do not care if a video exists at every frame from 0 to 3519, we care that a video starts at 0, and ends at 3519.
CZEditor ACTUALLY will target content creators. With the stuff that content creators really want, rather than the same corporate bullcrap that has been said by everyone else. CZEditor will support many features and make them easily accessible and accessibly easy. The features include:

1. Stylized/Realistic

D life advice to relatively late bloomer ML theory researcher.

Hi ML Community out there, I'm 27 M. I'm a machine learning incoming PhD student based out of Germany. I have been trying to get into a PhD program since last 4 years (since 2018). When I gave up and got into a masters instead with 3yoe. Now I'm about to complete my masters thesis and start a PhD.

I already have mixed feelings about my PhD journey now. I have gotten a really good opportunity to do ML theory at University of Saarlandes in Germany. Initially, when I had started, I was really driven to understand maths and underlying concepts of ML. However, more recently I have become more confused about the value of theoretical research and it's "real" impact. Of what skills I would have in my career later that would make me desirable to employers (considering I may not get tenured in academia).

Is it more advisable in long run to stay and get your PhD or just leave and join some ML role in industry that takes Masters guys and get some real world experience on how to use ML to generate business value ?

There is this added fomo of being 27 and just
