ERROR ImproperlyConfigured: Error loading psycopg2 or psycopg module

I'm currently trying to update a Django rest api on AWS Lambda using the following command.

zappa update dev

However it gives me the following error

Error: Warning! Status check on the deployed lambda failed. A GET request to '/' yielded a 502 response code.

When I run the following

zappa tail

I see the error

ImproperlyConfigured: Error loading psycopg2 or psycopg module

Does anyone know how to fix this error? I check requirements.txt file and it has the latest version of both psycopg2 and psycopg2-binary (2.9.10). I don't know why I'm getting the error.

Automated Dataset Generation for Object Detection

# What My Project Does

This project shows how we can generate custom synthetic datasets for training object detection models. Think of it like making your own training data on demand, especially when getting real-world images is a headache.

# Target audience

This project is designed for individuals who want to learn how to create their own datasets for computer vision tasks but are tired of the usual data struggles. It’ll walk you through the whole process, from coming up with ideas for your data to automatically labeling it, so you can skip the endless manual work.

# Comparison

Right now, if you need data to train a custom object detector, you're usually stuck either spending forever labeling stuff yourself or dealing with the hassle of finding and paying for existing datasets. And even then, it might not be exactly what you need. But now, with all these AI vision models and image generators popping up, there's a new way to do things. Instead of the usual manual grind, we can use LLMs and vision models to create the training data we actually need. Since there are tons of these models out there, both free and paid, you've got a lot of choices to find

What’s your library “stack”?

Hello! I’m switching to Django for my personal projects haven’t spent a lot of energy using Go, which I love but I have had to reimplement a lot from scratch.
I’m curious to know what are your go-to libraries for the most common needs (but feel free to drop any amazing library worth mentioning) so that I can migrate what I usually do in go to Django.

I’ll mention what I’m thinking of using so far:

- Django rest framework to implement rest api (I’ll focus on react + drf for my projects)

- djoser for authentication (I’d need jwt and social)

- celery for async events and crons

- throttling, I think drf offers a solution using django-redis

- Django-impersonate to impersonate users for troubleshooting purposes

- uploading files to s3 instead of local storage

- channels for webhooks and web sockets

- permissions/groups/roles to allow disallow users from accessing other users’ resources (images and documents included).

How do you manage sending mails with SMTP with all analytics and tracking on SES?

I am looking to have a custom implementation for sending and tracking mails. SES can do tracking, but I want to have a robust mail sending system. I have tried listmonk and it does not track for campaigns and the customizability is limited there. I'm looking to build a custom sender.

Is there anything I should avoid while building this? Is send and forget the right way and forcing SES to manage delivery +other analytics the best way?

Does anyone have some repos with a really good implementation of a mail sending system?

Django courses focusing beyond the basics

Most online courses focus on zero-to-one content (introducing the basics of a language or framework). I'm planning on creating micro-courses that go beyond stage one.

These micro-courses,

focus on one outcome
have a series of tasks/objectives to complete (learning by doing)
can be completed within a week by spending a few hours a day and
cover intermediate or advanced concepts

Examples,

1. Implementing webhooks for payment gateways
2. Processing webhook payloads the right way
3. Deploying a Django application on a VPS
4. Developing CLI tools for application housekeeping
5. Monitoring 500 errors in LIVE/PROD servers
6. Designing a backup policy and automating backups

Would you be interested in such micro-courses?

Any topic that you wish to add to this list?

Flask project front end design and modification for non-technical web site owners

I'm creating a website for a company that want their clients to be able to login to a portal and submit jobs for the company to complete. All of this will be handled with Flask and the aesthetic and design of these portal pages is not that significant.

For the front end, the design is much more important and I don't want to have to design and hand craft every page. I really want to be able to separate myself as the developer as much as possible from the designer or content producers for the site. What options are there for incorporating something that will easily let the company design and update the front end pages themselves (or employ a designer to do so)?

There will only be a handful of pages (home page, about us, contact us, Ts & Cs kind of thing) so using a headless CMS would just be a monthly expense for something that isn't going to change or be used that much, but is something I still want to separate myself as the developer from. It would also mean that I can just crack on with solving the technical aspects of letting clients submit jobs rather than

Making a custom model function as a login user?

Hey there, I've ran into an issue where I've been trying to create a custom model which has some basic data and then log-in functionality? I'm able to log in as a superuser but not using the data in my custom model. (Migrations have been made) What am I doing wrong here? This is the custom model which I'm currently using.

class Resident(AbstractUser):
    """
    Custom User model representing HOA residents.
    """
    verbosename = 'Resident'
    firstname = models.CharField(maxlength=50)
    lastname = models.CharField(maxlength=50)
    address = models.CharField(maxlength=255, blank=True)
    phonenumber = models.CharField(maxlength=25)

    def str(self):
       
return
f"{self.firstname} {self.lastname}"

   
    groups = models.ManyToManyField(
        'auth.Group',
        relatedname='residentgroups',

(when) do i need to make things async

currently writing a mini reddit clone with flask and sqlite for the backend. i'm concerned that once things scale that i'll need better async support that flask cannot provide. how often is this a legitimate concern? i understand there are alternatives like quart but i want to know if it's flask that will likely limit me, if i need to be thinking about async functions at all, and if so what scenarios those would be.

Planning flask project

I'm mostly self taught and am coming more from ds than webdev. The only webdev / html / css / js experience I have is from following Miguel's tutorial for a small blog.

I am building a website that hosts some of my ML models and takes in realtime data, then performs inference. The data pipeline is done, it uses a pub sub model and pushes the data to Redis.

I'm wondering:
- Is flask suitable for this as it doesn't support async intrinsically. The data pipeline is async and handles the data no issue, I tested it to 100's of GB a day. I would hate to have to rewrite. Is it as simple as switching to quart if need be?
- I would like nice realtime graphs to display everything. How would I let the website know that a new data point has been pushed? Somehow I need Redis to talk to flask.
- How would I make some kind of graph to display financial data. Can bootstrap do this or do I need some js library.
- I'm writing it using blueprints. Are there any repositories / sites that have already made blueprints. Seems like a waste

How to structure project from beginning?

Have kind of a random question about django project structure and apps.

Let’s say you have an idea you want to test and get an MVP up pretty quickly. The end idea is complex and has many models and functionality.

Is it a good idea to separate functionally based on models into apps when you start or refactor later?

Let’s say as an example I have users, comments, projects, messages, and more.

Thanks!
