I Made a Massively Multiplayer Board Game to Test Django Channels

http://codewords.io/

I've been trying to get permission to run a game of it from the publisher and designer (CGE & Vlaada Chvátil) but I haven't heard back. I've found demonstrating that there's interest in what you're doing is the best way to get ahold of people. So..

Anyone interested in trying a massive game of Codenames over Twitch? Not quite "For Science!" more "For Engineering!" Which, let's be honest here, has a much better ring to it.

If you'd like to know more, I put up an FAQ up here: http://codewords.io/faq/

If you'd like to sign up to help, there's a form over there: http://codewords.io/

Screenshots and a game play overview can be found somewhere under this: https://imgur.com/a/3xtZC

Never haven’t heard of Codenames?! You’re in for a treat, it's one of this (or any) decade's best games. Here’s the super short rulebook (https://czechgames.com/en/codenames/downloads/).. And a video: https://www.youtube.com/watch?v=emlI43ZE9-c

Question about thread model of Flask application

Would it be safe to have the built-in Flask webserver running in the same process with other background tasks?
Performance should not be a problem as only 1-2 Users are accessing the system at a time. It would be very convenient to have only a single process with shared data running and the possibility to have application internal events shared between tasks.

Django-UserForeignKey - Automatically set the current user on a model (e.g., for created_by information)

Hi there,

today I want to show the Django community a library called **django-userforeignkey** (disclaimer: I know the author of the package in person, and I have contributed to that package too), that essentially allows you to add **created_by** and **last_modified_by** information to your Django Models like this:

class MyModel(models.Model):
title = models.CharField(max_length=128)
description = models.TextField()
created_by = UserForeignKey(auto_user_add=True)
created_at = models.DateTimeField(auto_now_add=True)
last_modified_by = UserForeignKey(auto_user=True, auto_user_add=True)
last_modified_at = models.DateTimeField(auto_now_add=True, auto_now=True)


And all of that comes without needing to read request.user in your views or forms! It's all done "automatically".

The github repo of **django-userforeignkey** including a quickstart guide is available here: https://github.com/beachmachine/django-userforeignkey - it's also published on pypi
I showcased this library in a video which is available here: https://youtu.be/iJCbYMgUDW8

Is there a way to put the result at the top of a notebook?

I've recently started using Jupyter Notebooks. I'm using Folium in them to create interactive maps. [HERE](http://gis.ironcountywi.org/jupyter/Remon_Project_2018-C.html) is a simple example. Is there a way to get the final map to the top of the Notebook so people see it first and don't have to scroll down to see how it was produced unless they want to? Thanks.

so. just spend 7 hours trying to set up my Android app to connect with django's csrf. let me save you some time

all of the everything about connecting to django using csrf and authentication talks about AJAX, and there is very little information about actually connecting with Android. Throw in the fact that Android httpurlconnection objects are obtuse, have terrible documentation, and there are no good tuturials about cookies that don't use some random persons half-baked personal library, and you get me spending 7 hours trying to get my app to log in.

so here heres how to do it.

#YOU NEED TO SET THE FULL COOKIE, NOT JUST THE CSRF TOKEN

**WRONG:**

csrftoken=3JR5KZ4tHrDRlPvVwufhrT8Zn83sklwk;

**CORRECT:**

csrftoken=3JR5KZ4tHrDRlPvVwufhrT8Zn83sklwk; expires=Tue, 13-Nov-2018 00:29:33 GMT; Max-Age=31449600; Path=/

grumble grumble grumble

I literally went into django.middleware.csrf and put in a bunch of print statements to try to figure out what was happening.

edit:

heres the full android code for setting the cookies (lots of non-important details omited):

URL url = new URL(serverURL + myurl);
//URL url = new URL(myurl);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestProperty("Content-Type","application/json");
//getFullCSRFcookie() returns the full cookie string with time stamps and everything
urlConnection.setRequestProperty("Cookie", getFullCSRFcookie());
urlConnection.connect();


Edit: love how the only comments basically boil down to "I don't know what your project is, but you're doing it wrong." Lol you keep being you, reddit

Flask Beginner

I've started to read Flask Web Development by Miguel Grinberg. I am on part two where we create a social blogging website. I feel somewhat uncomfortable with the information. It feels quite over whelming. Is this book a fast pace book or is flask from a beginner still quite complicated?

Maintain Production Server

I recently moved my Django app from Heroku to DigitalOcean to save some $$$. In my reading prior to making the switch, people noted that managing your own server on DO is more work than Heroku. They mentioned security patches and other maintenance that is required.

My question is, now that my app is up and running on DO, what ongoing maintenance should I be doing to keep it secure and running smoothly?
