Tracking user status in Flask

Hi everyone,

I am trying to implement user status(Online/Offline) tracking functionality in my Flask app. I have something, partially working, but is not polished and working as I need. In short, I want to be able to track the Online users, when user login his status updates to Online, respectively when the user logouts his status in the database changes to Offline and the last\_status\_update field(datetime) updates as well with the current timestamp. I have achieved that using SocketIO and it's working perfectly fine, but the user status updates to Offline only if he is using the Logout button which basically ends the session.

I would like to improve that functionality by updating his status if the user closes the tab or the browser, I guess that involves some kind of client-side script, but I can't make it work as i need. Any hints how I can implement the entire functionality? I know that the code is a bit messy, I accept critics and proposals how to modify the entire logic.

The config class and the sockets:

class Config:
SECRET_KEY = os.getenv('SECRET_KEY')
SQLALCHEMY_DATABASE_URI = os.getenv('SQLALCHEMY_DATABASE_URI_DEV')

pgmq-sqlalchemy - Postgres Message Queue Python client that using SQLAlchemy ORM

# [pgmq-sqlalchemy](https://github.com/jason810496/pgmq-sqlalchemy)

# What My Project Does

A more flexible [PGMQ Postgres extension](https://github.com/tembo-io/pgmq) Python client using **SQLAlchemy ORM**, supporting both **async** and **sync** `engines`, `sessionmakers`, or built from `dsn`.

# Comparison

* The [official PGMQ package](https://github.com/tembo-io/pgmq) only supports `psycopg3` DBAPIs.
* For most use cases, using `SQLAlchemy` ORM as the PGMQ client is more flexible, as most Python backend developers won't directly use Python Postgres DBAPIs.

# Features

* Supports **async** and **sync** `engines` and `sessionmakers`, or built from `dsn`.
* **Automatically** creates the `pgmq` (or `pg_partman`) extension on the database if it does not exist.
* Supports **all Postgres DBAPIs supported by SQLAlchemy**, e.g., `psycopg`, `psycopg2`, `asyncpg`.
* See [SQLAlchemy Postgresql Dialects](https://docs.sqlalchemy.org/en/20/dialects/postgresql.html) for all dialects.

# Target Audience

[pgmq-sqlalchemy](https://github.com/jason810496/pgmq-sqlalchemy) is a production package that can be used in scenarios that need a message queue for general fan-out systems or third-party dependencies retry mechanisms.

# Links

* [PyPI](https://pypi.org/project/pgmq-sqlalchemy/)
* [GitHub](https://github.com/jason810496/pgmq-sqlalchemy)

WAT - Deep inspection of Python objects

https://github.com/igrek51/wat

# What My Project Does

This inspection tool is extremely useful for debugging in dynamically typed Python. It allows you to examine unknown objects at runtime. Specifically, you can investigate type, formatted value, variables, methods, parent types, signature, documentation, and even the source code.

Let me know what you think. I would really appreciate your feedback.

How to code better

I want to know if my implementation of the crud operation with the class-based view and the use of the dispatch function inside to handle specific methods (PUT, DELETE...) is a good idea.

Monthly Data Engineering Python Newsletter

https://alessandromolina.substack.com/p/python-data-engineering-july-2024

I have been working in the data engineering world for a few years, and have been contributing to many OSS projects that are foundations to it. This month I decided to start a dedicated newsletter to help everyone stay informed with what goes on in the data engineering world.

The Python Data Engineering newsletter was born as a way to scratch my own itch of having to keep up with updates to all the components that are foundations for data engineering projects in Python, and aims to be different from the usual ones that focus on data science and analytics, as it concentrates more on the fundamental building blocks needed to create platforms on which data science can run.

Hope it will be helpful for other people too and lightweight enough that it won’t introduce additional information overload for its readers.

Project Termatus: A TUI system informatics viewer, written in Python

What my project does:

Displays most of your system's informatics with a pretty TUI in your terminal.


Who is this for:

Well anyone wanting to style their setup or just see how their computer's doing


What's better about mine:

Colorful (i guess)
Nice big banner
Space for ASCII art and also custom art can be added
Completely in the terminal
Can work on Windows AND Linux

What's worse about mine:

UI would still be considered as lacking
Too much blank spaces that probably could be utilized in better ways
Some info might not be available on different OSes

This is highly customizable. Although there isn't a menu for that, you can just go into the source code and look for things you would wanna customize like colors, ascii arts, banner text etc. Just make sure it fits the dimensions


HEAVILY INSPIRED OFF OF BPYTOP

Disclaimer: This was created in windows. Although it has been tested on a WSL2 environment, still really dont expect it to work nicely on actual Linux OS

jinja2.exceptions.TemplateNotFound: templates/PatientView.html

I'm trying to create a simple Web App, fetching data from a MySQL table and displaying it on an HTML page. However, when I try running the .py file, I get the error: **jinja2.exceptions.TemplateNotFound: templates/Patient\View.html even though there is a Patient_View.html file in the templates folder.

Having Multiple Models Upload Files to Different Paths

I have 2 main entities, a Pharmacy and a Hospital, each of them can have one-or-multiple attachments, those attachments can be photos or PDFs.

Here's my Attachment model

class Attachment(Base):
    file = models.FileField(upload_to='attachments/')

    def __str__(self):
        return f'{self.created_at}'

and as an example here are my Pharmacy and Hospital models

class Pharmacy(Base):
    attachments = models.ManyToManyField(Attachment)
    ...

class Hospital(Base):
    attachments = models.ManyToManyField(Attachment)
    ...

My goal is to be able to put the attachments of a Pharmacy into a subfolder inside attachments/ and that subfolder should be pharmacy/, so everything lives in attachments/pharmacy/. And the same applies for a hospital.

I couldn't figure out the proper way to do this I even did a Google search which turned out with nothing. Any ideas?

D Every annotator has a guidebook, but the reviewers don't

I submitted to the ACL rolling review in June and found the reviewers' evaluation scores very subjective.

Although the ACL committee has an instruction on some basic reviewing guidelines, there lacks of a preliminary test for the reviewers to explicitly show the evaluation standards. Maybe we should provide some paper-score examples to prompt the reviewers for more objective reviews? Or build a test before they make reviews to make sure they fully understand the meaning of soundness and overall assessment, rather than giving some random scores based on their personal interests.
