How do I query a column in a custom wtf flask validator when using flask-ckeditor?

If I have a column in the db table with current_noscript = <p>A1</p> how do I query it in in flask and flask sqlalchemy.

In a flask wtf custom validator I tried
post_db = db.session.execute(db.select(Posts).filter_by(noscript=current_noscript)).scalar_one_or_none() but post_db is always None.


I know this because I went flash(post_db). I am 100% of the value because I checked dbeaver. Also the reason I am getting <p>A1</p> is because I am assume I am using flask ckeditor.


Though when I looked at dbeaver the text column is https://imgur.com/a/fDBobqZ. Notice the weird character at the end.
Here is the relevant code.

class Posts(FlaskForm):

    noscript =  CKEditorField('noscript', validators=[DataRequired('text is required'                     
    submit = SubmitField('Submit')]
 
class Book(db.Model):
    id: Mapped[int] = mapped_column(Integer, primary_key=True)
    text: Mapped[Optional[str]] = mapped_column(Text(), unique=True)

Error Appears After User Idles for A While (Assuming a Postgresql DB Connection Timeout) How can I handle this gracefully? Plus a ton of other questions.

`django.db.utils.OperationalError: consuming input failed: server closed the connection unexpectedly`

`This probably means the server terminated abnormally`

`before or while processing the request.`

`server closed the connection unexpectedly`

`This probably means the server terminated abnormally`

`before or while processing the request.`

While developing my app getting it ready for launch I have noticed that if I have accidentally left my dev server running overnight I see this error in the terminal when I refresh my browser and I get a 500 Internal server error in the browser.

My App is hosted on Railway using:

whitenoise==6.7.0
psycopg==3.2.2
psycopg-binary==3.2.2
psycopg-pool==3.2.3
gunicorn==23.0.0

Procfile:

web: gunicorn project_name.wsgi --log-file
web: python manage.py migrate && gunicorn project_name.wsgi

I am assuming I just need to change my procfile config to the following to prevent these issues. Also adding an 'CONN\_MAX\_AGE = 0' update to my DATABASES settings should correct the issue yes?

New Procfile:

release: python manage.py migrate
web: gunicorn project_name.wsgi:application --bind 0.0.0.0:$PORT --workers 3 --threads 2 --timeout 120 --master --log-level info --access-logfile '-' --error-logfile '-'

I want to hide the DRF API views in my production code.

I have built a full stack mobile-web application using Flutter and Svelte with Django as the backend. All of the mentioned codes have been pushed to production. All of them function on the Django rest framework APIs(GET,POST and DELETE methods).

I have deployed the Django code using Heroku, on entering the production URL API endpoints, you can see that the API views can be accessed to anyone (refer below)

Django admin not displaying registered LogEntry model

Hello, I've been attempting to display the Django built-in model LogEntry in the Django admin page, but it hasn't been successful. I'm using Django version 4.2.9. While my custom models are displaying correctly, the LogEntry model remains absent from the admin panel.

Here's what I've checked so far:

- Confirmed that django.contrib.admin is included in INSTALLEDAPPS
- Ensured the model is registered correctly within the appropriate app
- Even tried registering the model in a completely new (empty) app, which I added to INSTALLEDAPPS, but it still did not appear.

Do you have any suggestions on why this specific model isn't appearing? What else should I consider checking?

Project World's first autonomous AI-discovered 0-day vulnerabilities

I'm sure a lot of people have found 0-day vulnerabilities by pasting code snippets into ChatGPT. The problem has always been scanning an entire project for 0-days. Some papers have shown it's possible by feeding their agents known vulnerable code, but as far as I know, none of those papers ever got any CVEs or found real 0-days. Vulnhuntr was released this weekend with more than a dozen 0-days discovered in open source projects of 10k+ GitHub stars:

Monoranger: A poetry plugin for managing monorepos

🔗 Link - [https://github.com/ag14774/poetry-monoranger-plugin](https://github.com/ag14774/poetry-monoranger-plugin)

# What my project does

I recently needed to set up a monorepo and I wanted to have similar structure as in Cargo workspaces from Rust.

Essentially I wanted to have a single lockfile shared between all components/projects in the library and have a single venv with all dependencies installed as this makes development so much easier. I use Poetry so I decided to create a plugin for this usecase.

This plugin:

* Enables multiple projects in a monorepo using Poetry to use a shared poetry lockfile
* Enables multiple projects in a monorepo using Poetry to use a shared virtual environment
* Allows projects to use path dependencies and pin their versions during 'poetry build'

# Target Audience

Any Python developer that wants to create a simple monorepo using Poetry and does not want to resort to complex build tools such as Nx. I will be keeping this plugin up to date and make sure that updates and fixes are pushed in a timely manner

# Comparison

The existing tools fall in two categories:

a) Compicated build tools that have their focus on other programming languages but also support Python. An example of this is Nx. It's a nice tool but it has too many features

Help with Creating a Seat Model Linked to Backend in Bus Booking App


Hi all,

I’m working on a Django project for a bus booking system. I’ve already created the Agency and Bus models, but I’m stuck on how to implement the seat structure. Here’s what I’m aiming for:

• I want to create a Seat model that is linked to a Bus, which in turn is associated with an Agency.
• On the frontend, I want to display the seats as they appear in an actual bus (for example, in a 2x2 seating arrangement or other layouts).
• The seats need to be generated dynamically based on the bus assigned.

Could someone guide me on the best way to structure the Seat model and how to display the seats in the view? Any help on connecting these models and ensuring the seats are linked correctly to each bus would be appreciated!

Thanks in advance!

Hatch or uv for a new project?

I'm starting a new project, and I can't decide if hatch is needed anymore.
Hatch can install packages using uv for speed, so I used both before.

But uv allows monorepo, while hatch doesn't support it yet.

What are the differences between the two tools ? What would you choose for a new project?

cstructpy- Python package designed for binary serialization and deserialization of structured data

This app is open source and is made using Python: https://github.com/Maxim-Mushizky/cstructpy

Also can pip install it via pypi https://pypi.org/project/cstructpy/

# What My Project Does

Provides a simple interface for packing and unpacking binary data based on field definitions using Python's struct module. The motivation for this package is to have a data validation using type annotations, similar to pydantic but for binary data. Therefore this package is best when used alongside pydantic.BaseModel or dataclasses.dataclass since it allows a similar class structure and object creation

# Target Audience

Mostly effective for distributed systems, where there are c like structs passed as binary and need to be verified in different parts of the code.

# Comparison

There are no current comparisons, since this project attempt to mimic the object creation and validation as present in Pydantic

# Contribution

If you require any new features or have a use for this package you are more than welcome to join as a celebrator

Enjoy!

REST API Testing - Where to run functional tests?

Hello,

At work, I'm developing a REST API with flask, and I'm wondering where I should run my functional tests.

My current CI/CD pipeline on github actions runs the unit tests (mocking / patching ) for small blocks of code, and also runs the integration tests using a docker compose (spins up database instance, and some other services on the same machine, then runs tests)

Both those tests above run locally, and run during push and merges to github.

I also have functional testing for the REST API, using pytest with request library. Once the docker image is running in a test environment on AWS (EC2), I want to be able to make calls and check if the API is working properly

My question is where should these be run from and what do most professional organizations do? Should they run:

\- Locally? (i.e. my local computer send the request to the live test server on AWS)

\- On the Github action CI/CD pipeline? if so can i configure these to run after the docker image is running?

\- On the EC2 instance itself (maybe in another container)

\- Somewhere else?

Thanks for any advice!

jinja template rendering incorrect

Anyone know why jinja template statements would get borked while being rendered?

I have a couple of if statements in my config ie:

\## template: jinja
{% if distro == 'rocky' or distro == 'centos' or distro == 'ol' or distro == 'almalinux' or distro == 'fedora' or distro == 'redhat' %}



Is rendered as:
{0 if distro == 'rocky' or distro == 'centos' or distro == 'ol' or distro == 'almalinux' or distro == 'fedora' or distro == 'redhat' 0}

I do not know what process renders the jinja code, it was working then one day I started noticing all {% show up as {0 and making it where jinja can't process the variables.
Thanks

How do Session IDs work?

New to Flask. What I know is there are 2 ways to implement sessions: client-side and server-side. The former uses the default flask session (from flask import session) while the later uses a library called Flask-Session (need to add from flask_session import Session) .

I read both flask and Flask-Session docs, I still can't wrap my head around how sessions really work. The default session will turn your session data dict into cookie, then salt it, add signature, encode in base64. The Flask-Session's session still uses cookie, but it only contains the session identifier.

Session identifier is for identifying users, duh. But I have some questions:

1. Since Flask-Session is just extension of the deault session, do both of them implement the same approach to assigning session ID?
2. Where can I find the session IDs of the users?
3. Is it going to reset after closing the tab? browser?
4. When I do session.clear(), is everything cleared, including the session ID?

Again, sorry for asking these dumb questions. Any help would be appreciated. Thanks!

Ethics concerns and Google D

Apologies if this isn't the right place for this facet of ML, but it didn't seem against the rules.

I recently participated in an Alphabet human data research study used to evaluate AI agents and models.

Without going further into the details, the structure of the study felt very ethically questionable. The agreement said if there were any concerns, to contact HuBREC, human behavioural research ethics committee.

However, their email provided in the agreement hubrec@google.com does not exist and I have no point of contact at all short of looking up past academic talks and cold emailing people.

I am having a lot of difficulty searching for next steps as there is no other contact information I can use except for that email. I do know that Google has fired AI ethics researchers in recent memory, and that this topic never seems to be taken seriously. It seems like a bad look for an on-going study to point you to a committee that doesn't seem to exist.
