Creating 2fa with pyotp

I have a flask app that I'm trying to add a 2fa option to. I'm using pyotp to generate a code that will be sent via email.

The user signs in normally (email, password) and and if they've opted-in to 2fa they are then redirected to a page asking them to submit the security code they received in an email.

The challenge I'm facing is figuring out how I can carry the user object info to the 2fa route so that if they enter the correct code I can login\_user(user)

If they enter the correct email and password but the wrong code I need to retain the fact that they entered the email and password correctly on their following attempts.

There's a login route, and a 2fa code route.

Currently I have the 2fa code generated when the user lands on the 2fa route, there's a function called otp() that creates the one time password:


```
@app.route("/twofactor", methods=\['GET', 'POST'\])
def twofactor():
if current\_user.is\_authenticated:
return redirect(url\_for('login'))
else:
x = otp()
form=TwoFactor()
if form.validate\_on\_submit():

Noob Question: How to validate form when one button is pressed but not the other?

I have a very simple application going that allows you to either search a pokemon by name or get one randomly. I would like it so that my form is validated when submitting a name, but not when clicking 'random'. Currently, the form IS validated even when clicking the 'random' button. For example, if the field is empty and I click 'random' it complains about the DataRequired() validator. Here is the relevant code:


class PokemonNameForm(FlaskForm):
name = StringField('Enter a pokemon name...', validators=[DataRequired(), Length(3, 40)])
submit_button= SubmitField('Submit')
random_button = SubmitField('Random')

...

@app.route("/", methods=['GET', 'POST'])
def home():
form = PokemonNameForm()
pokemon = get_pokemon()

if form.is_submitted():

if form.submit_button.data:

Selenium over scrapy

I keep seeing posts about using selenium to scrape pages and I’m curious why people prefer that over a library like scrapy

I’ve worked with both and absolutely prefer scrapy — just wondering out loud

Behave Driven Development Python library

There are Python BDD frameworks out there, most notably `behave` (https://github.com/behave/behave).

They are nice. However, from time to time I find myself fighting against some design choices made by their authors. I thought that things can be made more lightweight, flexible and less constrained.

I thought that a tool with more of a library-like architecture, rather than a framework, might be fit for the purpose.

`Rumex` is my work-in-progress implementation of such a tool: https://github.com/uigctaw/rumex

I would appreciate any feedback. Be it minor things or fundamental ones - like perhaps I'm misguided in my assessment of perceived inflexibility of the existing tools.

Hosting recommendation

Hi all. I have a couple of dedi servers at inmotion, but they all lack the "Linux Cloud" feature and want to charge me rather high amounts to enable this feature. Ideally I was going to deploy via the "Setup Python App' in cpanel, but of course, this requires Cloud Linux.

Trying to do this without it via WHM has proven to be a nightmare and I was hoping somebody could recommend a suitable alternative for a domain (with sub domains), static IP and easy deployment of django apps?

Concantantion of strings from fields of model

I'm trying to combine values passed to fields name and surname to create a string to be stored in full\_name field. When l was looking for solutions, I found suggestion to overwrite Django's save method. I tried, but get no expected results. Instead after making a few instances of Author class and trying to loop over them in Django shell. I get following results:

> \--snip--/models.py", line 13, in __str__
>
> """Override save method."""
>
>AttributeError: 'Author' object has no attribute 'full_name'

When do you use Q?

A question that just came to my mind. I wrote:

etfs = ETF.objects.filter(Q(updated_at__lte=timezone.now() -timezone.timedelta(days=1)))

but to be honest, it's not a complex query. However, I am tending to automatically use a Q object. When do you use it, would you use it here?

I hope to read some opinions

Can you monitor multiple urlpatterns with Django's runserver autoreload

In the project I'm working on, I'd like to have it run 2 apps on one runserver for development purposes (standalone in production), to utilize amongs others autoreload options.

What I'd like to do is have wsgi application, and asgi application by implementing Django channels next to it. For that, I feel like I need to have 2 ROOT_URLCONFs basically, as one would apply to wsgi, and other to asgi application. I am interested is there a way to make runserver pay attention to multiple ROOT_URLCONFs or urlpatterns whatever you want to name them? And does this approach make sense in the first place, as from what I've seen on the web, it's not such an uncommon setup, but I haven't seen anyone placing it under one runserver.

For the ease of development setup it would be one server, as there's already an overhead on startup of the project development.

Deploy Django app using Docker or not...

So on my previous project (which right now has 300,000 page views per month) I tried using docker but kept having issues so I quickly gave up.

Instead, I ended up deploying it in AWS by using an EC2 Launch Template, so whenever a new instance is needed the template will launch and set up the instance (updates yum, installs Python, and Code Deploy agent). Then the Code Pipeline will deploy and run my application using the Code Deploy agent.

I also have a NextJs frontend application that gets deployed in the same EC2 instance. So whenever there is any autoscaling, both Django and Nextjs get scaled at the same time.


All the infrastructure is set up using a Cloudformation template which took me almost 1 month to figure out since it was the first time I was dealing CloudFormation, Code Pipeline, Launch templates, autoscaling, etc.


Okay that's it for my current architecture for deploying my Django Application.

​

For my current project I'm considering using Docker to deploy it on ECS. Here are the current reasons why I'm reconsidering Docker once again.


1. People have mentioned that deploying Django directly in EC2 server (manually or through launch template)

My Python-based Code Smells Catalog Paper was finally published in Springer! 🎉

Hey! Some time ago, I posted here my Code Smells Catalog website, which has a big pile of aggregated general Code Smells with examples & solutions written in Python.

Since then, the website is still reporting a daily activity of at least \~50 users and has an all-time peak of 8500, which is incredible! People seem to be using it both as a knowledge source and as a pointer for Code Reviews (referring to a particular Code Smell page).

Last month, my paper finally got published in Springer, which means a lot to me, and because of the occasion, I wanted to re-share the website catalog and paper (*pre-print* is free!) for those who missed it around a year ago.

Thank you all for your appreciation! It is so lovely that it brings at least a tiny bit of value to some of you! ❤️

Context Managers And The 'with' Statement In Python: A Comprehensive Guide With Examples

​

https://preview.redd.it/u6xczndjw7ya1.png?width=1600&format=png&auto=webp&v=enabled&s=373ea2365d45780156dd6d63bc86b70864513bce

Resource management is critical in any programming language, and the use of system resources in programs is common.

Assume we are working on a project where we need to establish a database connection or perform file operations; these operations consume resources that are limited in supply, so they must be released after use; otherwise, issues such as running out of memory or file descriptors, or exceeding the maximum number of connections or network bandwidth can arise.

**Context managers** come to the rescue in these situations; they are used to prepare resources for use by the program and then free resources when the resources are no longer required, even if exceptions have occurred.

Context managers provide a mechanism for the setup and teardown of the resources associated with the program. It improves the readability, conciseness, and maintainability of the code.

The context managers can be used with Python's `with` statement to handle the **setup** and **teardown** of resources in the program. However, we can create our own custom context manager by implementing the **enter(setup)** logic and **exit(teardown)** logic within a Python class.

In this article, we'll learn:

* **What is context manager and why they are used**
* **Using context manager with the** `with` **statement**
* **Implementing context management
