HTML form to Django backend

Hi there. I’ve been having problems with my first Django implementation. I’ve got an HTML POST form that I’m ultimately trying to get into my Sqlite3 db, and I’m fairly sure my views.py is where I’m going wrong by can’t seem to nail down why. Anyone have any ideas? [Link to stack exchange question ](https://stackoverflow.com/questions/54658622/getting-post-request-from-an-html-form-into-a-django-database)Thank in advance!

Asking for a review - That's a beginner app

Hello!

I feel a bit shy showing my code and I promise myself in 2019 to be less prudish.
Also, I think it is a good start to get the best practices asking for reviews to experimented guys.

​

So here we are:
I've started a Python/Flask project and I force myself to write raw SQL Request to get better with SQL (I think this is the most valuable things). I've worked with Ruby On Rails and ORM for 2 years now. Sometimes the ORM can't do what I want and have to process the result with Ruby which is known to be a bit slow. (especially old version).

​

This is only getting the data in the database and send it to the front which is processing with them and show me some Charts. I've only 3 routes and I feel like my file is getting bigger and bigger every time I'm looking at it.

**Gist:** [https://gist.github.com/jgengo/9fd005ec3b2aed935104c06bc95a3b34](https://gist.github.com/jgengo/9fd005ec3b2aed935104c06bc95a3b34)


Thank you for your precious time.

Flask-Alembic model detection - is very strange

Hi,

I found that Flask-Alembic detects model based solely on their using. So, if I add in the code something like that:

`from app.my_models import project_model`

the project\_model will be detected and, if there are any updates the table will be updated.

**But**, if I don't mention the model in the code it will be ignored as a non-existing model, and then, as a consequence, the table will be dropped from the database. It's slightly different from what I expected, or maybe I use it wrong.

Can somebody please comment on it?

Thanks!

Initializing a Flask app

[https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world](https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world)


With the above tutorial an `app` package is created. For the `__init__.py` file, `Flask` is instantiated in there:

app/__init__.py: Flask application instance

from flask import Flask

app = Flask(__name__)

from app import routes

Why is that written in \`\_\_init\_\_.py\` and what is the benefit of that? As opposed to an empty `__init__.py` and then instantiating the `Flask` class in another module such as...


app/main_app.py #Flask is instantiated here instead of __init__.py

from flask import Flask

app = Flask(__name__)

How to put CSRF tokens on the page without a flask form?

Since learning AJAX and RESTful api's, I've been replacing all my flask wtforms with regular ol' html inputs and submit buttons. I haven't really seen the point of wtforms. But they did have the .hidden\_token attribute which was nice.

So now that I'm doing away with flask forms, how do I still put a hidden token on my pages?

[R] OpenAI: Better Language Models and Their Implications

https://blog.openai.com/better-language-models/

"We’ve trained a large-scale unsupervised language model which generates coherent paragraphs of text, achieves state-of-the-art performance on many language modeling benchmarks, and performs rudimentary reading comprehension, machine translation, question answering, and summarization — all without task-specific training."

Interestingly,

"Due to our concerns about malicious applications of the technology, we are not releasing the trained model. As an experiment in responsible disclosure, we are instead releasing a much smaller model for researchers to experiment with, as well as a technical paper."

For those of you who got hired to work with Python, what coding challenges did they have have you do during the interviewing process?

I'd also appreciate knowing whether you thought those challenges accurately accessed the coding skills you needed to do your job.

Clustering Pollock

I applied kmeans clustering to some of the Pollock's paintings. The idea was to track the artist's usage of #colors through the years. Here's the outcome!

I had really good fun in mixing computer science and art. I used Python with the standard data science stack (pandas, numpy, scikitlearn) plus opencv. echarts for the visualizations at the end of the article .

Let me know what you think!

Django high level architecture diagram

Hi,

Was just windering if anyone has done a graphical architectural view of a typical django project. I think this would be enormously valuable for beginners particularly, for grasping how a project should be put together. I'm happy to try and start one, but my knowledge is quite lacking so would only be able to go as far as some of the tutorials out there, so would need help with it.
