Picodi - Simplifying Dependency Injection in Python

# What My Project Does

[Picodi](https://github.com/yakimka/picodi) is a lightweight and easy-to-use Dependency Injection ([DI](https://en.wikipedia.org/wiki/Dependency_injection)) library for Python. Picodi supports both synchronous and asynchronous contexts and offers features like resource lifecycle management. Think about Picodi as a decorator that helps you manage your dependencies without the need for a full-blown DI container.

# Key Features

* 🌟 Simple and lightweight
* 📦 Zero dependencies
* ⏱️ Supports both sync and async contexts
* 🔄 Resource lifecycle management
* 🔍 Type hints support
* 🐍 Python & PyPy 3.10+ support

# Quick Start

Here’s a quick example of how Picodi works:

import asyncio
from collections.abc import Callable
from datetime import date
from typing import Any
import httpx
from picodi import Provide, init_resources, inject, resource, shutdown_resources
from picodi.helpers import get_value


def get_settings() -> dict:
return {
"nasa_api": {
"api_key": "DEMO_KEY",

FastAPI Backend Template for SaaS products

Hello there, I just created a template for creating a backend for your SaaS products.

What my project does: It is a FastAPI project/template for creating SaaS backends and admin dashboards.

Comparison: 
Out of the box, it supports
1) Licence key generation and validation.
2) OAuth 2 authentication with scopes.
3) Endpoints with pagination and filters to easily integrate with an admin dashboard.
4) Passwords are securely stored using hashing.
5) used PostgreSQL for database

Would this work?

I’ve never developed or even tried proton native, but could you use proton native as a front end and then Django as a backend?

I’m curious because I would prefer this to PyQT or Tkinter.

How to display some extra information while using the CheckboxSelectMultiple widget?

I have a User model that has a ManyToManyField to an EmailCategory model -

class User(models.Model):
email_categories = models.ManyToManyField(EmailCategory)

class EmailCategory(models.Model):
name = models.CharField(max_length=20)
description = models.CharField(max_length=500)
def __str__(self):
return self.name


I am using the `CheckboxSelectMultiple` widget to render the user's `email_categories` field. It works correctly, but it only shows the name of the email category. I also want to show the user the description of the email category. How can I achieve that?

This is the form I am using -

class UserUpdateForm(forms.ModelForm):
class Meta:
model = User
fields = ['email_categories']
widgets = {

Flask for SaaS product and microservice arhitecture


I am currently given task to work on system design for MVP application for SaaS solution selling microproducts.

Users will pay for lets say notifications, specific data, and different type of things in application.

My idea is: Next.js for frontend, Auth0, API gateway and flask microservices.

From your expirience, what is the benefit of flask compared to Django or FastAPI for this kind of project that will potentially have thousands of active users?

Should API gateway be responsible for authorization based on what microservices user bought or better to keep it in code/microservices?


Any insight/doucmentation and experience is greatley appreciated :)

Easiest and good-looking frontend framework

Hi everyone!
I am a Data Scientist exploring the world of software engineering, particularly working with Django.

I have very little experience with frontend development (only with HTML, CSS, some frameworks like Bootstrap and Tailwind, and a bit of JS), and I don't know more powerful "tools" like React or others.

What is the best approach for a complete beginner who wants to create a professional looking app in a not too complex way?

I have also experimented with using templates and REST APIs: personally, I believe that APIs give you more flexibility, but on the other hand, I find them very complex to implement (it's probably just my fault): what do you suggest?

Thanks in advance!


EDIT: What if I want to create a fully functional web app' with payments, and a free (trial) mode? So, Is it possible to create a SaaS?

Apologies for the dumb questions

You should only use licensed version of python

I’m an intern in a company and I automated some processes using python. My company’s IT wing said that as long as it is a licensed software you can use it in our company.

In my mind I was like where the f I’m going to get a license for an open source software.

Note : They mention that another team has been using licensed python. I thought either IT is so stupid or that team is so smart that they brought license for pycharm or anaconda (claim that it is a Python license) and fooled IT.

If I am wrong then tell me where I can get that license.

And I am also looking for job in data analyst.

Setting image back to default image

I have a quick question pertaining to setting image back to default image. I have a user profile model:

from django.contrib.auth import get_user_model
User = get_user_model()

class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
image = models.ImageField(default="user_images/default.png",
upload_to="user_images", null=True, blank=True)
email = models.EmailField(null=True, blank=True)
following = models.ManyToManyField(User, blank=True, related_name='children')

My question is why doesn't the default image get applied to the image field when an user updates the profile after deleting his or her profile image? I fixed the issue by overriding the save() method, but I would like to understand why. Can someone explain it? Thank you very much.

def save(self, *args, **kwargs):
if not self.image:
self.image = 'user_images/default.png'
super(Profile, self).save(*args, **kwargs)

Best way to store Discount Code used in a purchase when codes are allow to change over time

Let's say you have the following models:

class Product(models.Model):
vendor = models.ForeignKey(Vendor, on_delete=models.CASCADE)
name = models.CharField(max_length=255)
price = models.DecimalField(max_digits=6, decimal_places=2)

class Purchase(models.Model):
customer = models.ForeignKey(User, on_delete=models.CASCADE)
total = models.DecimalField(max_digits=8, decimal_places=2)

class PurchaseItem(models.Model):
purchase = models.ForeignKey(Purchase, related_name='items', on_delete=models.CASCADE)
product = models.ForeignKey(Product, on_delete=models.CASCADE)
quantity = models.IntegerField(default=1)
price = models.DecimalField(max_digits=6, decimal_places=2)

class Discount(models.Model):
vendor = models.ForeignKey(Vendor, on_delete=models.CASCADE)
code = models.CharField(max_length=50, unique=True)
discount_percent = models.IntegerField()



If I want to store which discount code was used for a purchase I can do something like this:

class PurchaseItem(models.Model):
