Currently learning flask and need a bit of help. Please see below

Hi all, I am currently using flask to create a budget api application below are two tables:

from flasksqlalchemy import SQLAlchemy
from flasklogin import UserMixin
from datetime import datetime

db = SQLAlchemy()
```

from flask_sqlalchemy import SQLAlchemy
from flask_login import UserMixin
from datetime import datetime
db = SQLAlchemy()
class User(db.Model, UserMixin):
__tablename__ = 'users'
id = db.Column(db.Integer, primary_key=True)
username = db.Column(db.String(80), unique=True, nullable=False)
password = db.Column(db.String(255), nullable=False)
expenses = db.relationship('Expense', backref='user', lazy=True)
class Expense(db.Model):
__tablename__ = 'expenses'
id = db.Column(db.Integer, primary_key=True)
title = db.Column(db.String(100), nullable=False)
amount = db.Column(db.Float, nullable=False)
date_created = db.Column(db.DateTime, nullable=False, default=datetime.utcnow)

Do you really need microservices?

I was recently asked by a friend if they needed to use microservices in their project.

My answer is: it depends.

In general, microservices are a great way to structure your code so that it is modular, easy to maintain, and easy to scale.

However, there are some tradeoffs that you need to be aware of before deciding to use microservices.

Mainly because microservices add complexity to your system. This can make debugging and troubleshooting more difficult. It can also lead to increased latency due to the overhead of communication between services.

However, microservice (in my experience) is great for large-scale projects, where you need the flexibility to add or remove components as needed. It also allows greater control over how individual services are deployed and managed.

Goa and Kong are some of the best frameworks to develop and deploy microservices. They provide features such as out-of-the-box support for service discovery, routing and authentication that make it easier to build more complex applications. There are also newer architectural frameworks with less steep learning curves like GPTDeploy that lets you build and deploy microservices with a single command.

But If you did decide to go with microservices, make sure you have a good reason for doing

"Should" i normalize everything ? Data modeling question

Hey guys,

I have a model called Problem that contains many fields : difficulty, status, category.

Each of these fields have 3 entries. For example, difficulty field has these values : "Easy", "Normal", "Hard".

Should i create a whole model with its own table just for the difficulty field and make it a foreign key of the Problem model ? As below :


from django.db import models

class Difficulty(models.Model):
name = models.CharField(max_length=50)

def __str__(self):
return self.name

class Problem(models.Model):
name = models.CharField(max_length=50)
difficulty = models.ForeignKey(Difficulty, on_delete=models.CASCADE)

def __str__(self):
return self.name

Or should i just create a multiple choice field and keep the logic in my code :

from django.db import models

Bevy v2.0

I've created a dependency injection framework that works similarly to Fast API using type annotations. You only need to use the inject decorator and the dependency function to indicate what should be injected.

Installation

pip install bevy

Simple Example

from bevy import dependency, inject

class Demo:
def init(self):
self.message = "Hello World"

@inject
def example(thing: Demo = dependency()):
print(thing.message)

example()

That'll handle creating an instance of Demo and injecting it into the example function.

Your Django-Docker Starter Kit: Streamlined Development & Production Ready

Hey there,

I've crafted a Django-Docker starter kit titled "**Django-Docker Quickstart**" to kickstart your Django projects in no time.

This kit includes Django, PostgreSQL, Redis, Celery, Nginx, and Traefik, all pre-configured for your ease. Nginx and Traefik are set up for your production environment to handle static files, proxy requests, route requests, and provide SSL termination.

You'll also find tools such as Pytest, Pytest plugins, Coverage, Ruff, and Black, making your development and testing process smoother.

Check it out here: **Django-Docker Quickstart**

Enjoy coding and please star the repo if you find it helpful!

P.S: Feedback and suggestions are always welcome! 🚀

Took a web development job without much experience, am I doomed?

Okay so please don't ask how or why, but for the next year or so 50% of my 40 hour work week will be dedicated to developing a web application for a public authority.

The goal is to develop an application that offers users to fill out an extensive evaluation about sustainability.
Afterwards, they should receive information and visualizations/diagrams building on their answers. They should also receive a score for their sustainability in different categories and suggestions to improve on.
Both the answers and the suggestions should be stored in a connected database.

That’s about it.
I have a little bit of programming experience.
I know the basic principles like classes, objects, control structures like if/for/etc.

I don’t really have experience in web development though apart from fooling around a bit in Django. Honestly that’s why I want to choose Django as a framework for it.

Do y’all think it is possible if I spent around 20hrs/week on this project?

Obviously the first step would be to learn Django and web development in general the next couple weeks.

I would appreciate any input and also tips for any resources to start off.

Running Multiple Gunicorn Instances for Low-Traffic Websites

I've been exploring the use of Gunicorn and Nginx to serve Django websites, and it's generally recommended for its performance benefits. However, I have a question regarding running multiple websites on the same server with Gunicorn.


If I want to run multiple websites, it seems that I need to run separate instances of Gunicorn for each site. My concern is whether this approach will unnecessarily consume CPU and RAM resources, especially if the websites have low traffic.


In the past, I've used a LAMP stack to run multiple websites without requiring dedicated processes for each site. This makes me wonder if the modern approach with Gunicorn and Nginx is better in terms of resource usage and efficiency.


Could anyone shed some light on this? Am I missing something in understanding the benefits of running multiple Gunicorn instances for multiple websites, even if they have low traffic?


I appreciate any insights or experiences you can share.


Thanks in advance!

word2num: Convert complex "word numbers" to numerical values

Hey all, I just published my first Python package called word2num. It converts written numbers like "one hundred and twenty-five" or "nine and three quarters" to their numerical values. There are a handful of other packages out there that do this already, but they're mostly no longer maintained and do not support fractional values (the key feature I need for my project).

It supports a variety of types of numbers and uses configurable fuzzy string matching to account for typos. It only supports English at the moment, but contributions for other languages would be more than welcome.

If you want to give it a try, you can pip install word2num.

from word2num import word2num
word2num("twenty nine and a half") # 29.5

Check out the GitHub repo for more usage info and examples. My experience in Python is quite limited, so if anything comes across as non-Pythonic, I'd appreciate a heads-up! 🙌

The Ultimate Django Guide for Beginners and Beyond

Hello, fellow Redditors! I remember the days when I first started learning Django. It was both exciting and challenging, and at times, I wished I had a comprehensive guide to help me navigate this new territory. That's why I decided to write this in-depth article on Django – to make the journey easier for you.

This guide explores everything from Django's history and core features to its project structure, comparison with other Python frameworks, and the future scope of Django development. It's a resource I wish I had when I started, and I hope it can be beneficial for those who are just beginning or looking to deepen their Django knowledge. Dive in, explore, and let's enter the fascinating world of Django together!

N Anthropic - Introducing 100K Token Context Windows, Around 75,000 Words

Anthropic has announced a major update to its AI model, Claude, expanding its context window from 9K to 100K tokens, roughly equivalent to 75,000 words. This significant increase allows the model to analyze and comprehend hundreds of pages of content, enabling prolonged conversations and complex data analysis.
The 100K context windows are now available in Anthropic's API.
