Having hard time implementing search functionality in django

I'm a complete beginner in backend development and I'm currently working on a search functionality that includes multiple advanced filters. I'm using Django Filters for filtering, but since I'm new to this, I haven't found many tutorials on YouTube. Most of the content I came across relates to Q objects, which raises the question of which is better to use: Django Filters or Q objects?

Additionally, I'm gathering data from APIs for weather, air quality, and datasets related to the cost of living. I'm unsure how to store this data so that when users apply filters in their searches, the system can display relevant cities. The project is aimed at digital nomads looking for cities based on specific criteria.

I would greatly apprciate any guidance on these topics, and I apologize if my questions seem basic.

A search engine for all your memes - written in Python.

The app is open source and written entirely in Python 👉 https://github.com/neonwatty/meme\_search

# What My Project Does

The open source engine indexes your memes by their visual content and text, making them easily searchable. Drag and drop recovered memes into any messager.

The backend is built using these great open source components:

moondream: a tiny, kickass vision language model
all-MiniLM-L6-v2: a popular text embedding model
faiss: a fast and efficient vector db
sqlite: the swiss army knife of dbs

# Target Audience

This is a toy project. Open source and made for fun.

# Comparison

immich: great open source image organizer, does not (yet) have powerful image-to-text indexing
other local photo apps: some allow for indexing but not quite at the level of a vlm yet

Guidance on deployment

Hi guys!!
So, I have a flask application that I want to deploy over the internet for data transmission between a webhook application and a computer doing a bunch of scientific calculations.

The idea is to deploy this app to be visible over the internet, so I can send post request (from the webhook) to the flask application, the flask application request the calculation from the machine, and send it back.

So, I'm wondering if I need some special configuration to protect the network or it should be fine just with flask. (Note such service will not be available for anyone but the backend function with the IP address and port of the machine that request the calculations).

Also, the machine running the post get request should the same one as the one running the scientific calculations or in the same local network.

Can anyone point out the risk of such idea (vulnerability on the system) or any other recommendations?

From jupyter to vscode

Hi everyone, I’ve been using Jupyter notebooks for a while, but as my files grow larger, maintaining them has become cumbersome. I’d like to switch to VSCode to run selected code for testing, but every time I do, I have to rerun the entire code. How do machine learning engineers or data analysts handle large notebook files efficiently?

D R LLMs frameworks for research

I'm a Ph.D. student in AI and NLP and I'm currently starting a new research project with LLMs.
This time, instead of writing all the code from scratch, primarily using HuggingFace and Pytorch, I'd like to use one of the popular frameworks (like LangChain, LlamaIndex etc.).
The motivation behind this is that, ideally, I'd like to learn to use these tools to get a more compact and organised codebase, such that I can easily add pieces to include RAG, Agentic workflows etc.
I'm also interested in having an efficient way to load models and make inferences.

In your experience, which of the many available frameworks out there is the most suitable for research purposes ? And do you even use a framework or you just code everything from scratch every time you start a new project ?

How to run science projects

I’ve put together my experience for running ML & science projects based on 9+ years at a FAANG company. It covers the usual stuff like figuring out vague business problems, finding the right stakeholders, setting up metrics, and getting things done. I also share some personal stories about what’s worked (and what hasn’t), especially when stakeholders aren't on the same page. If you’ve done similar work or have different approaches, I’d love to hear what you think!

How call a Django API from inside a Django process?

I have complex Django app with many different endpoints and pretty complicated filtering.

I want to build an export service that accepts the URL and query string. The makes a call and it pages thru the data writes to a file.

For example, say there is a User API:
"/api/users/?namestartswith=Bob"

Consider the database is larger and there are 100k "Bobs". I want to page thru this and write results to a file.
Finally, the query sets behind the API are sensitive to which user calls them. So the results are dependent on request.user.

For large exports, this has to run in background task. The question is how in the background test do I effectively fake the user auth. I can't just copy the user auth over as it may/will expire.

I could easily write the ORM again, but I really want to use the existing filters and validated business logic.

The only way I have come up so far is to use some of the test infrastructure like the RequestFactory to make the calls inside my task. We do this all the time in our tests.

Alternative is to make some auth feature that allows for user impersonation which seems dangerous.

Am I doing it wrong for only using HTML and vanilla JS?

I've made webapps with VueJS before but it struggled with SEO. For the SEO part of that project I had to create a separate Flask-rendered page and import Vue as components on the page. I have not learned Nuxt yet.

Recently I tried Alpine.js for one project and then vanilla JS for another. I find it's easier to just use vanilla JS for the most part. Maybe because I'm relatively new to JS so I felt the vanilla JS is easier to grasp than frameworks. Granted these are very simple apps maybe that's also the reason. Am I missing something for not using a framework like Vue for simple apps? Does anyone use vanilla JS for a medium-complexity app?

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:
