PyHash Checker - A GUI app to check the cryptographic checksum of a file.

I made an app that generates the cryptographic hash of a file and compares it with the hash entered and shows if the given hash matches with the generated hash.

GUI made using PyQt5

Effizient way to let a Django/flask app communicate with a ESP8266 Board?

At the moment I have only 2 ESP Boards that I would like to control via Web, and if this goes well, some more in the future. These Boards are supposed to control some lights and a couple of relays. I would like to control them via web, but with one central application.

The first thing that came in mind, is either a Flask or Django application.

But how would I achieve the communication between the web application and Boards? My general idea is that the Boards are the clients, only listening to commands and the web app is sending the instructions.

Neat little program I made finally finished in the latest Pyt

I'm just getting back into things, and it's been a long time. I finally upgraded to 3.11 from 2.5 because it's been so long. I'm basically back to newbie. I was getting good in 2.5 and didn't want to upgrade then. Anyways, here's a program I just fixed I made yrs ago. I figured it might help some just getting started. Enjoy!

What should you do in order to be not indexed by Google, and other search engines?

Dear Flask developers,

I just don't want my website to be indexed by Google and other search engines. Every Blueprints' base.html file, has the code below as the head section.

{% block head %}
...
<meta name=”robots” content=”noindex,nofollow”>
...
{% endblock %}

\-Is it enough?

\-If it is not enough, could you please list the other necessary actions in other to be not indexed by search engines?

\-Do I need to tamper the WSGI file?

Old-School Adventure Game with PyGame (love letter to Shadowgate)

For years, I've been wanting to put together and old-school PC adventure game (like Shadowgate or Maniac Mansion). I've never really had the time to sit down and put everything together (mostly, its just too time consuming to paint or draw all the game assets).

However, I recently discovered Midjourney as a quick way to generate assets. And, combined with PyGame "under the hood"; I am pretty impressed with how things are shaping up.

Everything in these screenshots (except the text) was generated for me in a couple of minutes with Midjourney (with a bit of post-processing on my end).

My game only has a few rooms at the moment, but, I've got the hang of things now and it should be fairly easy to see this to completion.

How to write a simple password changer?

Hi,

can you please explain how to create a password changer? After providing first password to the user, user should be able to change their fist password with their preference. So I created the code below. Could you please provide the necessary part?

@app.route("/changepassword",methods=['GET','POST'])
@loginrequired
def userchangepassword():
form=ChangePasswordForm()
if form.validateonsubmit():
#They should enter their first password
#New password
#New password again
return rendertemplate('/passwordchange.html',form=form)


EDIT: Please check my new comment below. I updated the code.

Running a Function In a Template (beginner Question)

So I am building a front end for a LinkedIn web scraper and I am trying to get the function to run inside my template.

The function scrape from my Liscript.py file takes in two arguments (keywords and skills) and prints a table based on the results.

I am able to take in 'keywords' and 'skills' variables and reprint them in my html template but what I would like to do is import the scrape function and run it in my argsconfirmed.html template but I always get an error that says scrape is undefined. I'm also not sure if I should be running it in my .py file or my html template.

Thanks

&#x200B;

app.py file:

u/app.route('/argscomfirmed', methods=["GET", "POST"\])
def argsconfirmed():
from Liscript import scrape
    skills = request.args.get('skills')
    keywords = request.args.get('keywords')


return render_template('argsconfirmed.html',skills = skills, keywords = keywords)



argsconfirmed.html:

{% extends "LIfront.html" %}
{% block content %}
<h4> These are the keywords you chose are:</h4>
<h4> {{keywords}}</h4>
<h4> These are the skills you chose are:</h4>
<h4> {{skills}}</h4>
<h4>Data:</h4>
<h4> {{ scrape(keywords,skills) }}</h4>

How To Make Flask Apps The CORRECT Way

How's it going people? I've made a little crash course for "how to make flask apps." This tutorial is based on ironing out all the bs, issues, errors, and wrong directions tutorials make whilst trying to teach how to make flask apps. I'm not condemning them, but I want to show beginners how to make good flask apps without running into issues.

Repo link: https://github.com/Wizock/SuperiorPattern

# Video link: How To Make Flask Apps The CORRECT Way | The Superior Pattern

Please provide any feedback, I want this pattern to be as polished as possible so newcomers don't lose interest in web development because of stupid venv issues or circular import issues working with sqlalchemy db variable import issues.

Is flask-talisman still the way to go?

I'm getting close to publishing an app and am curious if people are still using flask-talisman or if there's something better I should be aware of?

It looks like it hasn't been updates since 2019 so maybe it's outdated?

Chime in if you've used it and or have other suggestions.

Thanks flask community!

Need guidance on a custom security manager.

I am running into some issues with my deployment. I'll give you some background before I explain what I'm trying to do and what I need guidance on.

I have a Flask/AppBuilder app running in a container. This runs fine and works as expected. I want to run it on AWS Lambda behind an API Gateway. So, instead of making a ton of changes to my code (I would still like to run the container in it's current form in a different environment) I am making use of the lambda-web-adapter. This essentially adds a lambda layer which forwards requests that come in to your application. It actually works, kinda. The issue I have is when servicing a request. The way the web adapter works is it boots the app up when initially deploying the function. Then all subsequent invocations are serviced by the already started app.

The problem I have is with the custom security manager I wrote. This looks for a specific header in the request, but the header isn't there. This is probably due to the mapping between API Gateway and the web adapter. Problem is, the authentication header is not present either. This is weird, since when I use

What is your development cycle when using docker and containers? What's the general flow between developing locally and running the containers to test.

I'm new to docker and I've done plenty with Django for internal tools within the company. However, I figured I wanted to take a shot at docker as I'm playing around with an application that could potentially go onto a cloud service.

However, what is your development cycle using docker? I guess I'm a bit hung up how you manage development locally or not, the migrations, etc.

So far, the idea I've come to is store my .env arguments in there to run in debug mode, and then use SQL lite. Then on the flip side, the container to run with debug mode off and postgres.

Just trying to get thoughts, ideas, and best practices from the community.
