I need some help with an issue regarding enumerations in Flask.



My model is as follows:



```python

class ApprovalStatus(PyEnum):

PENDING = 'pending'

APPROVED = 'approved'

REJECTED = 'rejected'



class Approval(db.Model):

id = db.Column(db.Integer, primary_key=True)

content_type = db.Column(db.String(50), nullable=False)

content_id = db.Column(db.Integer, nullable=False)

field_name = db.Column(db.String(50), nullable=False)

new_value = db.Column(db.Text, nullable=False)

status = db.Column(SQLAlchemyEnum(ApprovalStatus), default=ApprovalStatus.PENDING)



submitter_id = db.Column(db.Integer, db.ForeignKey('user.id'), nullable=False)

submit_time = db.Column(db.DateTime, default=current_time)

reviewer_id = db.Column(db.Integer, db.ForeignKey('user.id'))

review_time = db.Column(db.DateTime, default=current_time)

review_comment = db.Column(db.Text)



submitter = db.relationship('User', foreign_keys=[submitter_id\])

reviewer = db.relationship('User', foreign_keys=[reviewer_id\])



__table_args__ = (UniqueConstraint('content_type', 'content_id'),)



u/property

def content(self):

model = getattr(models, self.content_type)

return model.query.get(self.content_id)

```



However, I keep encountering the following error:



```

LookupError: 'pending' is not among the defined enum values. Enum name: approvalstatus. Possible values: PENDING, APPROVED, REJECTED

```

Just Released Version 0.4.0 of Django Action Triggers!

First off, a huge thank you to everyone who provided feedback after the release of version 0.1.0! I've taken your input to heart and have been hard at work iterating. I’m excited to announce the release of **version 0.4.0** of **django-action-triggers**.

There’s still more to come in terms of features and addressing suggestions, but here’s an overview of the current progress.

# What is Django Action Triggers

[Django Action Triggers](https://github.com/Salaah01/django-action-triggers) is a Django library that lets you trigger specific actions based on database events, detected via Django Signals. With this library, you can configure **actions** that run asynchronously when certain triggers (e.g., a model save) are detected.

For example, you could set up a trigger that hits a webhook and sends a message to AWS SQS whenever a new sale record is saved.

# What's New in Version 0.4.0?

Here’s a quick comparison of **version 0.1.0** vs. **version 0.4.0**:

**Version 0.1.0** features:

* Webhook integration
* RabbitMQ integration
* Kafka integration

**Version 0.4.0** features:

* Webhook integration
* RabbitMQ integration
* Kafka integration
* Redis integration
* AWS SQS (Simple Queue Service) integration
* AWS SNS (Simple Notification Service) integration
* Actions all run asynchronously
* Actions can have a timeout

# Looking Forward

As always, I’d love to hear your feedback. This project started as a passion project but has

Audio Book Reader: Read .epub, .rtf, and .txt as audio books!

https://github.com/RNRetailer/audio-book-reader



What My Project Does

This program is for the Linux terminal.

It breaks text files into lines and reads them out loud one line at a time.

Your progress for each file is stored in a .json file.

You can choose to skip to a certain line by passing it as a parameter when running the script.

Please make an issue or a pull request if you think any changes are needed.

Thanks!



Target Audience (e.g., Is it meant for production, just a toy project, etc.)

Anyone who uses Linux and wants to have a text file read out loud to them.



Comparison (A brief comparison explaining how it differs from existing alternatives.)

I haven't looked into alternatives in this space, I just made it on a whim.

How do I stop my Socket IO chat room from disconnecting users 30 seconds after joining the room? I'm hosting using Adaptable's free plan.

I've been working on a chat room application using Flask and JS where you can join a room and message people and it works fine on my local server but when I access the site from Adaptable, 30 seconds into joining a room, it boots the user out, so I was wondering if anyone knows why this is happening. I've tried a couple solutions already including implementing a heartbeat. Any help would be great, I'm just trying to diagnose the issue. Thanks!

My first flask app

As an avid sports lover, I've often faced the challenge of finding training partners, especially after relocating to a new city. This inspired me to create Sport CoTrain, a platform where fellow sports lovers can connect, post their activities, and find co-trainers.

I've built this app using Flask and basic HTML, keeping it simple yet functional. While it's still in its early stages, I'm excited to share it with the community and would greatly appreciate your feedback.

Sport CoTrain aims to solve a common problem for active individuals, making it easier to maintain an engaging workout routine and meet like-minded people. I'm looking forward to hearing your thoughts and suggestions to improve the app.

Thank you all for your time and potential input!

Complete Serverless Django Deployment

Hi,

I am planning to deploy a django (DRF) project. After doing a bunch of research AWS Lambda was the cheapest option. Did a little more digging and found Cockroach DB, it offers integration with Django and also offers Serverless pricing model.

So I made a final decision of deploying the django (DRF) project to AWS Lambda and use Cockroach DB with serverless model for database.


Anybody faced any issues with running Django in AWS Lambda with Cockroack DB in production? What are the cons that I can expect with this deployment plan?

Build web applications with wwwpy: For backend developers looking to minimize frontend headaches

All while providing strong customization, extension, and scalability!

Hey guys, my name is Simon and this is my first post.

I'm here for two reasons. One, share some thoughts about libraries you may be familiar with, like: Streamlit, Gradio, Dash, Anvil, Panel, Reflex, Taipy, NiceGUI, Remo, Pyweb, PyJs, Flet, Mesop and Hyperdiv. Two, get to know what problems you are dealing with that pushed you to use one of the above.

Don't get me wrong, the libraries listed have amazing features but I'm purposely looking at the missing parts.

Here are some pain points I've identified:

Slow UI rendering with big datasets or multiple visualization
Difficult to scale programming model and UI interaction
Extending or building components is costly, difficult or involving long toolchains
Overly simplistic architectures for complex applications
Scalability challenges in transitioning from demos to fully-fledged applications
Python runs server-side, while browser capabilities remain distant and restricted by the framework's architecture. (markdown, server side api, pushing updates to the DOM)



The famous libraries mentioned are particularly close to my heart because it's the field where I invested the most time working on. I've been developing software as a consultant for nearly 35 years and in the last 15 I developed web applications and

Library for generating REST API clients using methods annotated with type hints

What My Project Does

Meatie is a Python metaprogramming library that eliminates the need for boilerplate code when integrating with REST APIs. The library generates code for calling a REST API based on method signatures annotated with type hints. Meatie abstracts away mechanics related to HTTP communication, such as building URLs, encoding query parameters, serializing and deserializing request and response body. With some modest additional configuration, generated methods provide rate limiting, retries, and caching. Meatie works with major HTTP client libraries (request, httpx, aiohttp). It offers integration with Pydantic V1 and V2. The minimum officially supported version is Python 3.9.

Code Example

from typing import Annotated
from aiohttp import ClientSession
from meatie import api_ref, endpoint
from meatie_aiohttp import Client
from meatie_example.store import Product, Basket, BasketQuote # Pydantic models

class OnlineStore(Client):
def init(self, session: ClientSession) -> None:
super().init(session)

@endpoint("/api/v1/products")
