Django or Flask?

Hey everyone. I want to build small-to-medium scale web apps, where I take some inputs from users > process them > and generate some output. I am not storing much data but I need user authentication. So I wanted to understand which framework will be best for my use case. Django or Flask? And why?

Whatever TextField i fill all TextFields in other forms get filled

I created a Flask social media app, its landing page contains two forms(post, comment) both work fine in separate pages, but the landing page when they get combined. Whatever i write in the comment form it gets posted as a post, And i noticed when there is something wrong with validation all TextFields get filled with the same content I wrote.

Help with exporting PNG.

Hello there. Hope you can help me.

I create a image file from string by using htmlwebshot, the creation of the image is okay.

The problem comes when i try to make it response for downloading, by this way:

download = make_response(screenshot)

download.headers['Content-Type'] = "image/png"

download.headers['Content-Disposition'] = "attachment"

return download

After downloading the image can't be opened because is damaged. My image viewer says is not a PNG file, my WEB browser can open it, but my return in Flask says that is damaged.

​

How to make it response correctly?

I use this way to make response PDF files and works ok. So i supposed just change the Content-Type, and it will works.

​

Thanks for attention & answers.

Combining flask/fast api with django

Hi, I've been using flask for years now and also considering fast api for new projects.
But I really like the built in manager of django to manage the database. Im thinking of using django for backend user,(me). And a lighter framework like fast api for serving the production api. (They will be kept in separate server/containiers)
Is there a much better approach here?

Help required for hosting a flask app on a domain

Hey, so I have a Flask app built on my local which I now want to host on a domain (purchased on GoDaddy). All services that I have seen for this solution (PythonAnywhere, Linode, Ngrok etc.) are all paid. This is more of a hobby side-project so I am looking for something free. I don't need huge bandwidth or storage, just basic functionalities.

I have tried hosting this on PythonAnywhere, but it just keeps giving me username.pythonanywhere.com URLs, whereas I want it to be on my domain. Don't know what's the solution, maybe some unheard obscure library you can help with. Please recommend something worthwhile that can help.

Deploying Django with Celery

Hey,

I developed a REST API for a project I was working on with a few friends, and I ended up using Celery with Redis as the task broker. Currently, I'm deploying my development environment using Docker Compose. However, I'm exploring better and more sustainable solutions for a production environment that can scale both horizontally and vertically.

Can anyone guide me through some solutions that make sense? I understand that Kubernetes/K8s or ECS are viable options. I am currently trying to deploy this API using Kubernetes because, based on prior research, it appears to be provider-independent and aligns with my requirements. Still, I'd like to hear if any of you think there are alternative solutions that might also meet my needs with less effort.

Thanks in advance for your insights!

3y Django projects without using migrations

I'll need to apply several DB/code changes to a Django project that's at least 3 years old and has never used migrations for the existing models. The database used is SQL Server with SQL Management Studio. All DB changes so far have been made manually. I don't have contact with the initial developers so I don't know the reason why they did not use migrations for any of the apps they built. I do know at some point they migrated from Flask to Django, so that might be the cause.

While it seems like using migrations would be the most efficient way to maintain this project, I'm afraid to break things and make it even more complicated for other engineers touching this code as they are also not familiar with Django and migrations.

Considering how old the project is, would you still advise my team to start implementing migrations after all this time? If so, are there tutorials out there explaining how to do it safely? Please note that the DB names do not follow any of the Django default structure (appname_tablename).

I'm still a beginner in Django and DB management so apologies for any silly questions.

Advanced Python/Django tutorial that ties together multiple technologies

Hi! Is there an advanced Python tutorial that ties up multiple technologies?

What I mean by "advanced" is that it does not cover just the basics (syntax, loops, data structures), but goes beyond that. You should not be able to follow this tutorial unless you have the basics.

And what I mean by "tieing up multiple technologies" is that I would be interested to see it in the form of a project. A Django web app using Celery and Rabbit MQ running inside a Docker and deployed to AWS EC2. This would encompass Python, Django, Celery, RabbitMQ, Docker, AWS, and some more advanced topics concerning project organization and architecture.

​

Is there such a tutorial, or am I daydreaming and asking for too much?

Cheers! :)

flask_security_too fails with LiteSpeed server?

I have a Flask application that uses flask\_security\_too.

When the application is running on Gunicorn, everything is fine. However, on the production environment (public hosting) there's LiteSpeed server. While Gunicorn workers are up all the time, the LiteSpeed process is brought up only if there's a request to be handled, and it is shutdown after a few minutes of inactivity.

With this environment I've observed the following errors in application log:

High school student needs advice on development

Hi, I am developing a website with django, I don't want to get super detailed for ip reasons, but things I have sort of planned but could still change right now:

* I have to extend user model to hold "score" type information for users
* I will be using websockets with django channels for real time interaction between users
* I am using mysql with aws

Obviously there is a lot of work to be done and a lot of details to be hammered out, but I am relatively inexperienced with django as I have only done like two other small somewhat beginner level projects.


I am really just looking for advice. The project that I am working on is really important to me and it does not need to be done any time soon. Is it realistic to expect that I can get this done on my own? Where should I go to look for assistance programming or to find someone else to join? I have been developing for a while, and it seems doable but like it will be a lot of work.

Functions within getcontext()

I'm just working on the last stages of a project where I am building in the ability to capture the visitor IP address, time stamps etc etc (there will be the required privacy/GDPR/Cookie notices) which will be written to a log file.

I have the function to capture IP data, my initial thought was to put this in Middleware but I've tested it by placing it within my get\context() and it works. Is it good practice to put a function within a class view and call it from within the method, like below, so that the function is called when the page is requested? I initially thought about using some HTMX or JS to call the function from the client. Also, I'm using Wagtail, to be specific, but no difference.

This is the code structure, just wondering if this is OK, before building it out more, obviously I won't be writing to a file in production.

Introducing UniDep: Unified Conda and Pip Dependency Management

Hello r/python!

I'm excited to share a tool I've been working on called [**UniDep**](https://github.com/basnijholt/unidep) - a tool designed to streamline Python project dependency management by unifying Conda and Pip dependencies in a single `requirements.yaml` file. This approach allows for the creation of a unified Conda `environment.yaml`, while also integrating seamlessly with `setup.py` or `pyproject.toml`.

**Key Features of UniDep:**

- 🔗 **Unified Management**: Manage Conda and Pip dependencies together in a single file.
- ⚙️ **Project Tool Integration**: Seamless integration with `pyproject.toml` and `setup.py`.
- 🏢 **Monorepo Support**: Merge multiple `requirements.yaml` files into one Conda environment `environment.yaml`.
- 🌍 **Platform-Specific Support**: Specify dependencies for different operating systems or architectures.
- 🛠️ **Conflict Resolution**: Automated version conflict resolution for complex dependency chains.
- 🔄 **`unidep install` CLI**: A single command to install all Conda, Pip, and local dependencies.
- 🔧 **`pip-compile` Integration**: Generate fully pinned `requirements.txt` files from `requirements.yaml`.

**Getting Started:**

- Installation: Easily install UniDep via pip (`pip install unidep`) or Conda (`conda install -c conda-forge unidep`).
- [GitHub Repo](https://github.com/basnijholt/unidep): Check out the code, examples, and detailed documentation.

**Example:**

```yaml
name: example_environment
channels:
- conda-forge
dependencies:
- numpy # same name on conda and pip
- conda: python-graphviz # When names differ between Conda and Pip
pip: graphviz

Thank you django for getting me through my school project

A little background, my teachers, after not teaching us any html or css or javascript or much of python or any web dev, decided that we should make a simple CRUD website as a projects. Our teacher recommended laravel, which just didn't work for my group. None of us knew php and laravel was so large it was hard to wrap our heads around it.

Eventually I fould django and flask. In the end, we decided to use django because it had enough "batteries-included" that basically everything we needed (logins, simple database, an admin
site) was already there.

And I'm so thankful that the Django docs and tutorials are amazing. I am in love with how django does it's docs. Primarily the tutorial tours most major parts of django, and the "using blank" style articles which gives super beginner friendly advice on how to use things like the user object.

The experience was so good that I actually want to do more web dev stuff after this. Though probably not as a career since I plan on being a teacher (primarily out of spite)

Also our project was ass, it looked like garbage, there was a 6 layer div nest somewhere in the html, the

You watched me develop a full SaaS product as a community event. What's next?

Hey r/django,

about a month ago, I made this post. I asked whether you are interested in seeing me create a full SaaS product from idea to production deployment. You were interested! 500 of you joined the various channels.

I loved that response and delivered with a more than 6h long live stream (recording here: https://www.twitch.tv/videos/1973448363). The feedback was great, I didn't hear a single bad word.

But what now? The discord community is fairly active, posting and solving their problems. I love to see that, it's a small dream come true.

However, I want to do something like this again. A big project, maybe multiple streams long. I've also started telling a few business stories on request.

What is something you guys are curious about and would want to see?
