Flask changing src and PATHS

I've used Flask(__name__, template_folder="mijn_project/templates") for some reason all my PATHS don't work. app.py is stored in / and my project is stored in /mijn_project/. none of my templates can find the images location or bootstrap, css, js etc. but when I run my HTML template it show the CSS, images, lib without errors. what's going wrong? PS. the structure is not my idea, my teacher demands this. and I tried every PATH ../static, /static/, ../../static but nothing works. and its a local test

How do I get current values from the database in a dropdown form

Hi,

TL:DR: I want to pass the values of a database model into the options in a dropdown menu.

I am building a application with different card types. Each card type has a different color. To keep track of the users preferences I created a database model where for each user I keep track of their color (and also Icon and label).

Basically the user can say:- legend_1 is yellow, I call it "ambition" and I want a thumb up icon.- Legend_2 is blue etc etc

here is the model:

models.py

# Create your models here.
class CardPreferences(models.Model):
<!--Some other stuff not related to question -->
legendlabel1 = models.CharField(blank=False, maxlength=40, default='legend1')
legendhexcolor1 = models.CharField(blank=False, maxlength=6, default='78E7BF')
legendicon1 = models.CharField(blank=False, maxlength=40, default='thumbs-up-solid.svg')
legendlabel2 = models.CharField(blank=False, maxlength=40, default='legend2')
legendhexcolor2 = models.CharField(blank=False, maxlength=6, default='51c1ff')
legendicon2 = models.CharField(blank=False, maxlength=40, default='thumbs-up-solid.svg')

Database on Local Machine - Still Pulling Heroku Postgres Database

Recently my main computer rig died and I moved onto a new computer.

I am trying to get my local development mode back up and running but am running into trouble, amateur programmer at best, doing this as a fun hobby.

Anyways, in the process of trying to get the website back up and running, I forgot to set my local environment variable of "DEVELOPMENT_MODE" to "True" and ran "python manage.py collectstatic" and "python manage.py runserver" and my local machine points to the postgres database that I have on with Heroku.

I thought this should be a pretty easy fix and change "DEVELOPMENT_MODE" to "True", but the local database is still referencing the postgres database. Any ideas on how to get django to point the the local sqlite3 database?

Code in reference, settings.py:

if DEVELOPMENTMODE is True:
DATABASES = {
"default": {
"ENGINE": "django.db.backends.sqlite3",
"NAME": os.path.join(BASEDIR, "db.sqlite3"),

Flask Sessions not working with blueprints

I am using flask sessions, i recently changed my code structure to be blueprint based, it has broken sessions. Whevenver i try to access sessions inside a blueprint, it is giving me

RuntimeError: The session is unavailable because no secret key was set.  Set the secret_key on the application to something unique and secret.

This is the code from the main application:

app = Flask(__name__)
app.register_blueprint(authModule, url_prefix='/auth', cookie_path='/')
app.secret_key = environ.get('secret_key')
app.config['SESSION_COOKIE_PATH'] = '/'

Can anybody tell me what is causing this?

Announcing Polyfactory - a powerful mock data generator for dataclasses, Pydantic and more

Hello r/Python!

Today I'd like to formally announce the first stable release of Polyfactory \- a powerful mock data generator built around type hints and support for some of the most popular data modelling solutions such as Pydantic models, dataclasses, typed-dicts and more!

## Once upon a time there was pydantic-factories

Some of you may already know this project as "pydantic-factories"; A name under which it garnered a decent amount of popularity since it's inception. Pydantic-factories and Polyfactory have a lot in common. In fact, Polyfactory is pydantic-factories 2.0. That's why we also decided to continue the version number and release the first version of Polyfactory as 2.0.0.

But why the name change?

A main motivator for the 2.0 release was that we wanted to support more than just Pydantic models, something which also required a change to the pydantic-fatories' core architecture. As this library would no longer be directly tied to Pydantic, polyfactory was chosen as a new name to reflect its capabilities; It can generate mock data for dataclasses, typed-dicts, Pydantic, odmantic, and beanie ODM models out of the box.

Polyfactory is all that pydantic-factories was and more!

## So what can it do?

Let's look at a very basic example using dataclasses:

Fluke v0.3.0 has been released!

Fluke is a Python package that can be used to easily read files that do not reside within the local file system, e.g. on a remote server or on the cloud, as well as transfer them between said locations.

Most changes introduced in version 0.3.0 are focused on reading files, adding functionality regarding reading large files in chunks, partially reading files, and more.

Trying to implement symmetric encryption in a secure way

Hi friends. Need some guidance here.

I'm creating a Django app which encrypts some fields before storing in Db (using custom fields). I want the server to have little to no knowledge of the contents (not able to get to zero knowledge yet).

So here's what I'm trying to do:

When the user signs in, use the password to generate a key using PBKDF2
Put it in session storage
Use this key to encrypt/decrypt (using AES) any sensitive data they enter
Once they logout, session gets cleared, key gets destroyed, server has no way to decrypt the data

# Q1

Is this a good approach? Or are their better alternatives or packages which already implement this sort of thing?

# Q2

I'm currently using PyCryptodome to generate PBKDF2 key, but it returns byte object which is not JSON serializable, and hence not able to store it as session variable. How do I go about doing that?

Using first name and last name as username

Building a Django site for my work. I want to make it simple and automatically assign a username based on the users first letter of their first name and then their whole last name.

I’m using Django Forms and following along with a tutorial to set forms up.

Can this still be achieved and how would it be achieved?

pytheus: a modern python library for collecting prometheus metrics built with multiprocessing in mind

hello, I wanted to share a library I've been working on for quite some time now.

It's a new python library for collecting metrics with prometheus with a focus on flexibility & multiprocessing. The last one is one of the main reasons for this to be born as I found it difficult to have multiprocessing work correctly with the existing ecosystem.

Going from single process to multi process is a matter of a "function call" and everything should work as expected without differences in features between the two.
The library also supports default labels and partial labels (incrementally build your child instance), and offers ways to easily plug in your own version of something if you so require via protocols. (For example a custom Registry or even a custom Backend for multiprocessing using something else, by default it uses redis).

A lot of focus was also given to the documentation to make it clear.
I hope that if you struggled in the past this might make the experience better! :)
