Deploying a flask app

Im currently building a small flask app.

Ive got it running locally while im building it. just running it on a development server using flask run.

I plan to deploy it to something like pythonanywhere.

Ive seen people online say to use something like Gunicorn since you should use development servers for production.

Im trying to wrap my head around it, but do i need to use a production ready server? wont that be handled by pythonanywhere once i launch it?

I made a Python app that turns your Figma design into code

Link: https://github.com/Axorax/tkforge

Hey, my name is Axorax. I have been programming for a few years now. I started making a lot more projects in Python recently and this is one of them. I decided to call the project TkForge.

What My Project Does TkForge allows you to turn your Figma design into code. So, you can make the UI for an app in Figma and add input fields, buttons and much more and name them properly then you can run TkForge to convert your Figma design into code. The names need to be the element that you want. For example; if you want a button element then you can name it "button" or "button Hello World!". The "Hello World!" portion will just get ignored. All of the text after the first space is ignored. However, for some elements, they matter. Like, if you want a textbox element with the placeholder text of "Hello" then you need to name it "textbox Hello".

Target Audience It is meant for anyone who wants to create a GUI in Python easily. Dealing with Tkinter can be a pain a lot of times and it also

What is the standard around using number vs UUID for primary field?

I understand using primary key as number sequence might not be best thing to do as it makes it easy to guess url but using uuid can be slow to index and search. I used slug filed before with name and last 8 characters or so from uuid. The easiest to implement common fields like this and created by, created at fields is using inheritance but not all models have name .
Wondering how is everyone handling this? Also want is the best way to get current user here?

Weird NOT NULL constraint error

Hi all


I'm new to Django, but have been coding for a long time.


I have a simple model with very few fields in one table. There are no foreign keys. I am using SQLite as the DB as I'm learning all this out. I have Django auto-creating the ID field for my model.


From what I have discovered reading online, this should work:
def delete(request, goal_id):
g = Goals.objects.get(pk=goal_id)
g.delete()

However, that throws a not null constraint on the name field. What is confusing to me is, isn't this deleting the entire row? Why would a constraint issue appear here?


When I go directly to the DB from the python command line, I have no issues:

>>> conn = sqlite3.connect('....../db.sqlite3')
>>> cur = conn.cursor()
>>> sql = 'delete from pps_goals where id = 10'
>>> rs = cur.execute(sql)
>>> conn.commit()


For completeness, here is the relevant portion of models.py
class Goals(models.Model):
objects = models.Manager()
name = models.CharField(max_length=50)
total_duration = models.DecimalField("total_duration","total_duration",5,3)

Any ideas what I'm messing up?

I am getting a error when I try to verify the password with argon2. It always come back as False.

What am I doing wrong? Here are the docs https://argon2-cffi.readthedocs.io/en/stable/howto.html Put simply

ph.verify

always returns

argon2.exceptions.VerifyMismatchError: The password does not match the supplied hash

ph = PasswordHasher() ph.verify(...)

Here is the code.

ASCII plot backend package for matplotlib

Hi

I've made a package called mpl_ascii which is a backend for matplotlib. You can find it here: https://github.com/chriscave/mpl\_ascii

I would love to share it with others and see what you guys think

What it is

It is a backend for matplotlib that converts your plots into ASCII characters.

At the moment I have only made support for: bar charts, scatter plots and line plots but if there's demand for more then I would love to keep working on it.

Target Audience:

Anyone using matplotlib to create plots who might also want to track how their plots change with their codebase (i.e. version control).

Comparison:

There are a few plotting libraries that produce ASCII plots but I have only come across this one that is a backend for matplotlib: https://github.com/gooofy/drawilleplot. I think it's a great package and it is really clever code but I found it a little lacking when you have multiple colours in a plot. Let me know if you know of other matploblib backends that does similar things.

Use case:

A use case I can think of is for version controlling your plots. Having your plot as a txt format means it can be much easier to see the diff and the files you are committing are much

I Made a Short Tutorial About How to Create Custom Management Commands In Django

Hello 👋,

A few months ago, I started making videos about coding because I found that it helps me retain concepts and it is a great way to share something I love with the world, which often feels really nice. My latest video is about 4 minutes long and it is about Custom Management Commands!

When I started learning Django, I was super excited about Custom Commands, and I still am. 😅 I really hope that by sharing it here, some one will find it useful.

In what way do you try out small things when developing?

I've noticed at work that my coworkers and I try out small things in different ways. Small things like if you want to try that adding two datetimes together behaves in the way you expect. Some people use jupyter notebook for this and others run python interactively in a separate command prompt.


I usually run debug in whatever IDE I'm using and then letting it stop at the code I'm currently developing and then using the debug console to test things out. Sometimes this means just leaving the debugger at a breakpoint for half an hour while I continue writing code. Is my way of doing it weird or does it have any disadvantages? How do you usually test out things on the go in a good way?

Djagno Advanced Roadmap

hi! I started learning django about a year ago I've covered all the basics I also learned DRF with a few advanced topics models, views, cbv, fbv etc... I want to reach the point where I qualify to apply for jobs in companies I want a complete and comprehensive roadmap for Django so that I can evaluate my level through it I learned node js , react & react native also as a matter of knowledge So that I will be aware of how the frontend works specifically, which will contribute to raising my level

​

I have already completed several projects as a freelancer

The last one was an ecommerce shop

But I could not determine whether my code was clean and of a high level of quality

any help?

Pure Python Physics Engine

What My Project Does The Physics Engine Called PhysEng, provides an easy to use environment and visualization combo in which to try out different physics or even provide a template to design your own accelleration/velocity fields. Besides the visualization aspect and numpy the basic functions of the Engine are written completely in 100% python. The features included in the Engine are:

Particles, Soft Bodies, Anchor points
Built in Fields: Drag, Uniform Force Fields, Gravity Between Particles, Octree Gravity etc
Make your own: There are standard templates included in the Examples to design your own fields
Springs - Construct Soft Bodies using Springs. (Built in soft bodies: Cloth and ball

Target Audience PhysEng is made for people who just want to try out different simple simulations or want to design their own physics.

Comparison Looking through github I could never really find a simple and easy-to-use library that did not require me to install some weird libraries or that felt like it was hiding some process from me through using packages. This package is a solution to this since everything is written in python nothing is a secret and can be directed easily.

How to automatically order M2M relations

Hi, I have a M2M relation as such:

)
category = models.CharField(
choices=ClothingType.choices, maxlength=10, default=ClothingType.TOP
)
weight = models.IntegerField()

Whenever I am using the Outfit queryset, I want the Clothing relation of each entity to be sorted with respect to the "item_category__weight". Is there a way for me to make this the default behaviour of the Outfit model. If

Are PEP 744 goals very modest?

Pypy has been able to speee up pure python code by a factor of 5 or more for a number of years. The only disadvantage it has is the difficulty in handling non python mistakes which are very commonly used in practice.

https://peps.python.org/pep-0744 seems to be talking about speed ups of 5-10%. Why are the goals so much more modest than what pypy can already achieve?
