Debugging async Django under Uvicorn with Pycharm
If you deploy Django async under ASGI, chances are you need an ASGI server like Uvicorn. In production, you can use Uvicorn with Gunicorn, but in development you might want to use Uvicorn standalone, which can also run programmatically from a Python script. This gives also the ability to debug your asynchronous Django project locally with any IDE. In this short guide you'll learn how to debug Django under Uvicorn with Pycharm. Running Uvicorn programmatically As a first step, create a Python script in your project root. I call mine server.py. In this file we import and run Uvicorn: import uvicorn if __name__ == '__main__': uvicorn.run("async_django.asgi:application", reload=True) Here I assume we have a Django project in the async_django folder, where we can also find a file named asgi.py, which is the ASGI application for our Django project. Once the script is ready we move to configure Pycharm. Configuring Pycharm to debug Django In Pycharm, open up the Run menù and click on Edit configurations. Here we create a new configuration for Python, to run our server.py: The Script path configuration should point to the path where server.py lives. Once done you're ready to debug your Django async project. Debugging async … -
Managing a Django Project with Poetry
Poetry is relatively new packaging and dependency manager. It makes it very easy to upload libraries to PyPI, manage dependencies visually, and has a couple of handy features. Today, I'm not going to do a deep dive into how Poetry works and all its features. Today I just want to focus on how to configure it for a Django project. -

Django: adding extra context data to a CreateView
Welcome back to another episode of my Django mini-tutorials! In this post we see how to add extra context data to a Django CreateView. What context there is in a CreateView? I already touched CreateView in this tutorial. In brief, CreateView is a Django class-based view complete of everything you need to create HTML forms in your Django pages. Here's how a CreateView looks like: class TicketCreate(CreateView): model = Ticket fields = ["subject", "message", "priority", "attachment"] success_url = reverse_lazy("clientarea") In this class-based view you specify a model to operate on, the fields you want to expose, and an optional success_url to redirect the user to, once the form has been successfully submitted. Now, a CreateView usually renders also a default template (unless you change it), which by convention takes the name of the model, followed by the word "form". For this CreateView for example, the template is ticket_form.html, which should be created beforehand in the template folder. Once rendered, the template gets a context, which in this case will include a form object which we can then render in the template. So, CreateView renders a form for editing the model, what if we want to include extra context data? Adding … -

Sending Invites - Building SaaS #77
In this episode, I worked on the form that will send invites to users for the new social network app that I’m building. We built the view, the form, and the tests and wired a button to the new view. The first thing that we do was talk through the new changes since the last stream. After discussing the progress, I took some time to cover the expected budget for the application to get it to an MVP. -

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: … -
