Django web app hosted locally

Hello, I am currently exploring Django because it has good security and my seniors suggested it. Currently they want me to use Django and have a super user and regular user. The super user can do CRUD (create, read. update and delete) data on the cloud/local data base. The regular user has a calendar dash board that has a search function and can search specific dates: Example: January 1, 2024 - it will then list down all the information of data from that specific date only.

My seniors are also pushing Mongo DB, both used for local for User:(Signup/Login) for local and another Mongo DB in cloud that is hosted either via AWS or Google providers of MongoDB.

Is this doable? and how will you tackle this if you are in my place? Thank you for suggestions/helps.

I need help with Django REST JSON parse error

I am very lost with this issue.

The stack is React, Redux, Django REST framework, Gunicorn, Nginx all in Docker.

I am sending a simple POST request from the frontend, all it contains is this data:

let data = {reportid: selectedReportId}

I verified that selectedReportId is not null or undefined. Viewing the request via browser tools, I can see the request and everything looks fine, including the JSON data.

However, it returns a 400 Bad request.

The urlpatterns in urls.py:

...
path('reports/generate/', views.generatereport, name='generatereport'),
...

The corresponding view:

@csrfprotect
@apiview(['POST'])
@permissionclasses(IsAuthenticated)
def generatereport(request):
data = JSONParser().parse(request)
reportid = data.get('reportid')

if reportid is None:
return JsonResponse({'Error': 'Submitted report ID does not exist'})
else:
report = getobjector404(Report, pk=reportid, user=request.user)

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_title = <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(title=current_title)).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):

    title =  CKEditorField('title', 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 '-'

DATABASES in settings.py:

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
