Example app that uses testing framework

I’ve developed using Django for awhile now, but admittedly have never built an app that used unit tests or the built in testing framework. I’d like to change this in 2019, but tend to learn best by examining working code rather than from books/videos.

Does anyone have a good, preferably small-ish/simple project using Django that incorporates unit tests they could recommend as an example that is open source?

I recreated Flappy Bird in Python with Pygame!

The link to the GitHub page is [here](https://github.com/carterjean/Flappy-Bird-in-Pygame/).

I thought that to learn Pygame I would start with a physics heavy, yet retro game.

On the page, you can download the images and file and play it for yourself!

One problem that I found is that I couldn’t find a way to automatically restart the game :/

If you have any problems with the game, just leave a comment and I’ll try and fix it!

Edit : not sure why there’s a massive picture of Garfield there but okay

Edit 2 : oh that’s my profile pic never mind

Accessing child relations when overriding save()

I am trying to wrap up my first app using Django (specifically Django Rest Framework which may change the save behavior), but have run into an issue that I haven't been able to solve for about 10 hours now.

I am trying to override the save() method of a model to modify a field on a bunch of child objects when it is created; however, I can't figure out any way get the objects or ids for the children.

My code looks something like:
~~~
class Parent(models.Model):
"""When I create this, I want the children to be modified."""
def save(self, *args, **kwargs):
if not self.pk:
self._begin(*args, **kwargs)
else:
super(Parent, self).save(*args, **kwargs)

def _begin(self, *args, **kwargs):
super(Parent, self).save(*args, **kwargs)
print(self.child_set.all()) # --> This gives: "<QuerySet []>"
for i in self.child_set.all():

[D] Adversary, Attractor, Astonishment : Subverting traps in Human vs AI games

Hi,

&#x200B;

I am an AI PhD student at MIT and I just wrote an (hype neutral) article discussing human vs AI in games in the context of the recent AlphaStar agent that learns to play Starcraft 2.

&#x200B;

Specifically, I discuss under which circumstances is it hopeless for a human to win, and under which circumstances do we have a good shot. Link here: [https://medium.com/@evanthebouncy/adversary-attractor-astonishment-cea801d761](https://medium.com/@evanthebouncy/adversary-attractor-astonishment-cea801d761)

&#x200B;

It should be a good read ! !

&#x200B;

I can answer any questions here as well, I do not work for DeepMind so I can be more frank in my answers, but at the same times these answers will largely be speculative as I do not work directly on the project.

Executing python code in pygame window

Hello everyone! I’m hoping someone can point me in the right direction. I made a text-based game using python. It requires text input for answering questions, navigating etc. The game works fine with no problems. I later realized that I wanted to add some graphics which lead me to pygame. My question is whether I am able to run my game in the pygame window or do I have to start from scratch. I just want my current game to run in the pygame window so that I can also add graphics to it. I’m completely new to all this. Thank you!

What to choose Django CMS or Wagtail?

Hi. I have read many tutorials about this two CMS and have tried demos, but couldn't finally choose what is better for my project.

The main purpose is simplicity for developer add/edit pages and project scalability - many fields of different types and dependencies between them. (Field changes it's value or range depends of another field choosing)
Who has practice working with this two frameworks?

I am having trouble with extensions in JupyerLab: Code folding

Hi!

I have been happy to see that code folding seems to be implemented in JupyerLab:

[commit on github](https://github.com/jupyterlab/jupyterlab/pull/5761)

I am kind of new to github. It says, that this pull request is merged to the master branch. But how do I get this version? Do I simply update jupyter lab?

And how do I activate the extension? I installed nodejs according to the [extensions documentation](https://jupyterlab.readthedocs.io/en/stable/user/extensions.html).

I have been searching the web a lot about how to do this, but have not been able to do that.

I am running jupyter lab 0.35.4

How difficult is it and how long does it take to become a remote Django developer?

I’ve been studying Django on and off for the past year or so. I’m hoping to become a django fullstack developer as soon as possible. For those who were able to become a remote developer, can you shed some light on your experience and the route you took? Is it difficult to become a remote developer and how long did it take you to become that?

Also, what stack are you on? Is it easier to become a django backend and do JavaScript angular/react etc front end instead of doing just Django for both?


I’d like to travel and work at the same time so any tips or advices would be appreciated.

[D] Are we expected to solve hard programming challenges to work in ML/DL industry?

Lots of tech companies hire people based on programming challenges. People [quit their job](https://medium.freecodecamp.org/why-i-studied-full-time-for-8-months-for-a-google-interview-cc662ce9bb13) to dedicate months preparing for an interview. [Cracking the Code Interview](https://www.amazon.com/Cracking-Coding-Interview-Programming-Questions/dp/0984782850) is the #1 best-selling book in programming and software development. Even if a person has a strong experience in developing real-world software, they [may fail an interview](https://twitter.com/mxcl/status/608682016205344768) because of a CS/coding question.

I understand that there is a correlation between people that can solve these challenges and people that can do real-world software engineering, but I believe that this correlation is not as strong as companies believe. People may just overfit to these challenges and get a job without getting their hands dirty in real software development.

Enough of my rant.

I work as a ML/CV software engineer in the same company for five years. I did not have a single interview in the meantime. I'm considering applying to another job and I'm worried about the coding challenge interviews. I can produce well-written and maintainable code. I can understand, discuss, and implement recent advances in computer vision. But give me a simple data-structure interview challenge and I will struggle to solve it without looking at some references.

Am I expect to solve hard programming challenges during interviews for

How can I remove the 'static/' from URLs of static files?

I have my images and icon files in a folder called `static`. This is for internal organization.

Publicly, the URLs for these files are like this:

example.com/static/icon/favicon.ico

But I want them to be like this:

example.com/icon/favicon.ico

How can I achieve this?

7 years of Programming, starts from this book

Hello Redditors,

7 years ago, I was a college student. My college doesn't teach me advance programming, but only basic of all programming language ( I learn from QBASIC, Visual Basic, Java, Cobol, C, C++, and more).

I love C/C++ back then, but I found some barrier while learning it. The barrier is: Different compiler and preprocessor while using different OS.

So I decided to learn one language that running in all platform. The first choice is Perl. I love because I can simplify and "code golfing" while code. But Perl is not my answer, because after 1 week writing the code, I forgot why I wrote in that way. I create many vapor code using Perl.

So, I need other solution for it. And my choice is Python.

&#x200B;

My college doesn't teach me Python, so I decided to **pirate** [this book](https://www.amazon.com/Learning-Python-5th-Mark-Lutz/dp/1449355730). For 1 month and 2 weeks, I learn that e-book.

I also create some script for my private hobby (scrapping from online manga, automation file clean up), and much more.
After about 6 month practice with Python, I try to apply programming job using the knowledge I know.

For about 2 years works after that, I finish my college also pay all my college
