Implemented Full-Stack Web App with Next.js and Django Rest Framework: Facing CSRF Verification Issues Hey everyone, I've recently developed a full-stack web application using Next.js for the frontend and Django Rest Framework (DRF) for the backend. For authentication, I used Simple JWT. Everything was going smoothly until I encountered a problem with CSRF verification failures. It seems like my requests from Next.js to the Django backend are being blocked due to CSRF token mismatches. Here’s a brief rundown of my setup: Frontend: - Next.js - Axios for making HTTP requests - Integrated authentication using JWTs from the backend Backend: - Django - Django Rest Framework - Simple JWT for token-based authentication The Issue: When I make authenticated requests from my Next.js app to the Django API, I keep getting CSRF verification failed errors. I've tried several solutions, including adding CSRF tokens to the requests and configuring CORS settings, but nothing seems to work. Has anyone faced similar issues or have any suggestions on how to resolve this? Any help or guidance would be greatly appreciated! Thanks in advance! Feel free to adjust the details to better fit your specific situation. /r/django https://redd.it/1e4hiys

Is SQLAlchemy really that good? I've read a lot about SQLAlchemy and it seems to get a lot of hate for bad documentation or poor performance. I heard Peewee is a good alternative that's much more optimized and easier to use. The question is though, why is SQLAlchemy still so popular and widely used in industry? I heard it's the go-to for startups who choose Flask for their projects. Personally I work with raw SQL queries The only advantage of SQLAlchemy I can sense is when defining tables and data, it's much easier to make the change, while with raw queries, you must modify each query string statement individually. For projects that use many tables with tons of columns that might be exhausting. But if the performance concerns are true, how does SQLAlchemy get away with it? /r/flask https://redd.it/1e4bbjj

Unable to type texts to chatbot user input Hey guys, first time posting here. I am trying to add a chatbot for the backtesting platform built with Flask and there is a button on the right side that toggles the sidebar. If the user clicks the button, it shows the sidebar with a chatbot. But I'm going through an unexpected bug and would be utterly grateful if you guys could help me out. I'll add this link(https://stackoverflow.com/questions/78752558/unable-to-type-texts-to-chatbot-user-input) that I posted on StackOverflow with the HTML, CSS, JS codes, and app.py code. # Expected Behavior The user should be able to type texts into the chatbot user input field. # Current Behavior Currently unable to type texts into the chatbot user input field. https://preview.redd.it/l8l04x804tcd1.png?width=1914&format=png&auto=webp&s=81080e4a4efb536d9a9a4c9c9a29ff4f56082a63 /r/flask https://redd.it/1e4fj86

Docker for Flask I have been trying to look for online solutions and practices followed but generally they do it for the flask template app which does not cover the cases for real-world large scale applications. I personally have worked on numerous flask applications but while deploying am never successful in actually implementing the Dockerfile. Kindly guide me on how to tackle this. /r/flask https://redd.it/1e42cx3

Django devops without Kubernetes I'm not trying to use Kubernetes and AWS EKS. They're too overkill for my current project. How can I deploy without downtime while not using Kubernetes? I want to avoid deployment downtime at all cost. /r/django https://redd.it/1e408bc

OpenSkill MMR Rating System Now Features Per Player Weights What My Project Does OpenSkill is a peer-reviewed multiplayer ranking and rating system you can use to implement matchmaking systems on top of. This rating system behaves "like" TrueSkill, but is full open source, and unencumbered by patents, or trademarks. TrueSkill (Microsoft's proprietary, and patented rating system), has had something similar to this feature called "partial-play" for a while now. Our implementation is fully typed, supports pypy, and cpython and has 100% test coverage. So what's this new change? Well there are not many open source rating systems (at least that I'm aware of) that let you consider in-game player scores to be factored into the rating updates. Only got 1 kill while the rest of your teammates got 4 or 5 kills? The rating system will update it's beliefs about a player based on these metrics. This means faster convergence to your actual skill. Target Audience I hope this new feature is useful to the game development community, especially those making multiplayer games. There is a lack of support for the game development ecosystem in Python. So here's hoping, your next multiplayer game finds use of this project! Comparison Some alternatives include EloMMR, Glicko-2 and TrueSkill. All of these are lacking in some areas. GitHub Source /r/Python https://redd.it/1e42ds7

I made GestureFlow to improve my productivity! # What My Project Does GestureFlow is an innovative application that enhances the traditional right-click functionality on computers by introducing a customizable radial menu. Here's what it does: 1. Radial Menu Activation: When you hold the right mouse button for a short duration (200ms), a circular menu appears around your cursor. 2. Quick Action Selection: Move your mouse in the direction of the desired action and release the button to execute it. No need for precise clicking on small menu items. 3. Customizable Actions: The menu includes common actions like Copy, Paste, Undo, Redo, and more. These can be easily customized or expanded in the code. 4. Visual Feedback: The menu provides clear visual feedback with hover effects and color changes, making it intuitive to use. 5. Cross-Platform Compatibility: GestureFlow works on both Windows and macOS, automatically adjusting its keyboard shortcuts for each platform. 6. Efficient Workflow: By combining multiple actions (e.g., "Select All + Copy"), it reduces the number of steps needed for common tasks. # Target Audience GestureFlow is designed for: 1. Power Users: Individuals who value efficiency and customization in their daily computer use. 2. Professionals: Developers, designers, writers, or anyone who frequently uses context-based actions in various applications. 3. Accessibility Enthusiasts: People interested in alternative input methods that /r/Python https://redd.it/1e3jye6
