Generating random avatar images in Django/Python
tl;dr; <img src="/avatar.random.png" alt="Random avataaar"> generates this image: (try reloading to get a random new one. funny aren't they?) When you use Gravatar you can convert people's email addresses to their mugshot. It works like this: <img src="https://www.gravatar.com/avatar/$(md5(user.email))"> But most people don't have their mugshot on Gravatar.com unfortunately. But you still want to display an avatar that is distinct per user. Your best option is to generate one and just use the user's name or email as a seed (so it's always random but always deterministic for the same user). And you can also supply a fallback image to Gravatar that they use if the email doesn't match any email they have. That's where this blog post comes in. I needed that so I shopped around and found avataaars generator which is available as a React component. But I need it to be server-side and in Python. And thankfully there's a great port called: py-avataaars. It depends on CairoSVG to convert an SVG to a PNG but it's easy to install. Anyway, here's my hack to generate random "avataaars" from Django: import io import random import py_avataaars from django import http from django.utils.cache import add_never_cache_headers, patch_cache_control def avatar_image(request, seed=None): if … -

gettext, JSX and ES6 template literals
gettext, JSX and ES6 template literals I really like using gettext to translate hardcoded strings into other languages. Django’s translations functionality relies on it as well. Unfortunately, the xgettext executable which is responsible to collect translatable strings in your code has a bug where it just stops processing files when encountering ES6 template literals inside JSX tags. Support for ES6 template literals was added earlier this year but combining those literals with JSX still doesn’t work. I wrote a small Python script to extract *gettext calls from JavaScript files; the current version is here. The idea is to find all JavaScript files using git ls-files "*.js", using a regular expression to find *gettext calls and write the output to a place where Django’s ./manage.py makemessages finds it. I’m certain the code will break too with strange error messages in the near future but it seems to work well, for the moment. Here’s the current version of the code (hopefully) for your enjoyment: #!/usr/bin/env python3 import re import subprocess def js_files(): res = subprocess.run( ["git", "ls-files", "*js", "*mjs"], capture_output=True, encoding="utf-8", ) return res.stdout.splitlines() def gettext_calls(file): with open(file, encoding="utf-8") as f: return [ match[0] for match in re.findall( r"""\b(\w*gettext\(\s*(['"]).+?\2\s*\))""", f.read(), ) ] … -

On using Markdown with Sphinx - onward to Evennia 0.9.5
Last post I wrote about the upcoming v1.0 of Evennia, the Python MU* creation engine. We are not getting to that 1.0 version quite yet though: The next release will be 0.9.5, hopefully out relatively soon (TM). Evennia 0.9.5 is, as you may guess, an intermediary release. Apart from the 1.0 roadmap just not being done yet, there is one other big reason for this - we are introducing documentation versioning and for that a proper release is needed as a base to start from. Version 0.9.5 contains everything already in master branch, so if you have kept up-to-date you won't notice too much difference. Here are some highlights compared to version 0.9: EvMore will paginate and properly handle both EvTables and database query output. For huge data sets, pagination can give a 100-fold speed-increase. This is noticeable e.g. in the scripts and spawn/list commands, once you have a lot of items.EvMenu templating language, to make it easier to create simpler menus. Webclient improvements: Cleanup of interface and the ability for players to save/load their pane layouts from the client. The developer can still provide a default for them to start out with.

Capped Social Network - Building SaaS #76
In this episode, I started a new project to build a different kind of social network. This social network will contain a max number of connections to encourage thoughtful choice when growing your personal network. We talked MVP features and put in the basics of a Django app. I had a wild thought to build a social network with a capped number of connection in the hope that users would choice their connections based on people that they really care about. -
A Django REST API in a Single File
I previously covered writing a Django application in a single file, for both synchronous and asynchronous use cases. This post covers the angle of creating a REST API using Django in a single file. Undeniably, REST API’s are a very common use case for Django these days. Nearly 80% of this year’s Django community survey respondents said they use Django REST Framework (DRF). DRF is great for building API’s and provides many of the tools you’d want in a production-ready application. But for building a very small API, we can get by solely with tools built into Django itself. Without further ado, our example application is below. You can save it as app.py, and run it with python app.py runserver (tested with Django 3.1). An explanation follows after the code: import os import sys from dataclasses import dataclass from django.conf import settings from django.core.wsgi import get_wsgi_application from django.http import HttpResponseRedirect, JsonResponse from django.urls import path from django.utils.crypto import get_random_string settings.configure( DEBUG=(os.environ.get("DEBUG", "") == "1"), ALLOWED_HOSTS=["*"], # Disable host header validation ROOT_URLCONF=__name__, # Make this module the urlconf SECRET_KEY=get_random_string( 50 ), # We aren't using any security features but Django requires this setting MIDDLEWARE=["django.middleware.common.CommonMiddleware"], ) @dataclass class Character: name: str age: … -

Prevent Unintended Data Modification With django-read-only
Last week I released a new Django package, django-read-only. It provides a read-only mode for Django’s database layer. This can be useful to reduce the risk of giving developers access to your production instances. Access to manage.py shell on production allows you to iterate faster when creating new features, migrations, and backfills. But with great power comes great accident potential. It’s all too easy to mix up terminal sessions and run the wrong thing on production. Even if the individual chance of making such a mistake is small, multiplying it by team size and time, the chance of a mistake can become almost certain, and the potential cost can be huge. Rather than locking your team members out of production, you can protect against these mistakes with django-read-only. The package uses some always-installed database instrumentation to block database access when its read-only mode is active. You can then enable read-only mode for interactive production sessions via an environment variable or setting, so when developers access production writes are disabled by default. Read-only mode can be disabled, so the occasional manual data fix is still possible. For example, if the environment variable was set, we couldn’t log into the shell and … -

Make A Landing Page - Building SaaS #75
In this episode, I added a landing page design to the app that I’m building. By using a Tailwind CSS landing page template, I could fit the design in with my existing CSS tools. I showed some available templates that I discovered while researching for Tailwind-based landing pages. Once I found a decent template, I copied the source of sample landing page into my index page template. Since I copy and pasted from the landing page, the initial look was terrible. -
