How to Get Hired as a Django Developer

Flask vs Django (2022)

Colossal Coaster and Stripe CSP - Building SaaS with Python and Django #152
In this episode, we did an Exercism excercise that looked at Python list methods. Then we dug into Stripe and got to the bottom of some warnings reported by Firefox about potential Content Security Policy issues. Ultimately, we discovered some interesting additional Firefox cookie protection that were not found in Chrome. -

How much faster is Cheerio at parsing depending on xmlMode?
Cheerio is a fantastic Node library for parsing HTML and then being able to manipulate and serialize it. But you can also just use it for parsing HTML and plucking out what you need. We use that to prepare the text that goes into our search index for our site. It basically works like this: const body = await getBody('http://localhost:4002' + eachPage.path) const $ = cheerio.load(body) const title = $('h1').text() const intro = $('p.intro').text() ... But it hit me, can we speed that up? cheerio actually ships with two different parsers: parse5 htmlparser2 One is faster and one is more strict. But I wanted to see this in a real-world example. So I made two runs where I used: const $ = cheerio.load(body) in one run, and: const $ = cheerio.load(body, { xmlMode: true }) in another. After having parsed 1,635 pages of HTML of various sizes the results are: FILE: load.txt MEAN: 13.19457640586797 MEDIAN: 10.5975 FILE: load-xmlmode.txt MEAN: 3.9020372860635697 MEDIAN: 3.1020000000000003 So, using {xmlMode:true} leads to roughly a 3x speedup. I think it pretty much confirms the original benchmark, but now I know based on a real application. -

Programmatically control the matrix in a GitHub Action workflow
If you've used GitHub Actions before you might be familiar with the matrix strategy. For example: name: My workflow jobs: build: strategy: matrix: version: [10, 12, 14, 16, 18] steps: - name: Set up Node ${{ matrix.node }} uses: actions/setup-node@v3 with: node-version: ${{ matrix.node }} ... But what if you want that list of things in the matrix to be variable? For example, on rainy days you want it to be [10, 12, 14] and on sunny days you want it to be [14, 16, 18]. Or, more seriously, what if you want it to depend on how the workflow is started? Let's explain this with a scoped example You can make a workflow run on a schedule, on pull requests, on pushes, on manual "Run workflow", or as a result on some other workflow finishing. First, let's set up some sample on directives: name: My workflow on: workflow_dispatch: schedule: - cron: '*/5 * * * *' workflow_run: workflows: ['Build and Deploy stuff'] types: - completed The workflow_dispatch makes it so that a button like this appears: The schedule, in this example, means "At every 5th minute" And workflow_run, in this example, means that it waits for another workflow, in … -
Handy tool: pyupgrade
An advantage of open source is that, ideally, you get to work with other programmers from different companies and different backgrounds and different toolchains. They do things differently and so you can pick out the choice bits and start using them yourself. As an example, z3c.dependencychecker. A small tool I started in 2009 based on someone else's script. The goal is to look at all the imports in your python code (or apps in django settings files or...) and compare them to the list of requirements in setup.py. What's missing? What can be removed? The last few weeks, gforcada did some nice modernization/cleanup. Removing support for older python versions, for instance. And a move from travis-ci to github actions. So I looked at the new action workflow and saw something new. Black, isort, flake8: I know and use them. But pyupgrade? What is that? That's how I discovered pyupgrade. Handy tool to upgrade your code to newer python versions. By default, it removes python 2.x stuff that is no longer needed, like # -*- coding: utf-8 -*- at the top of your file. super() calls no longer need to mention the super class. The is not that flake8 tells you … -

Django Settings Patterns to Avoid
This post is an adapted extract from my book Boost Your Django DX, available now. It has a 50% discount for the Black Friday sale, until the end of Cyber Monday (28th Nov), plus a further 50% off for those outside the GDP top 50. Here are some potential mistakes made with Django settings that you can avoid. Don’t Read Settings at Import Time Python doesn’t make a distinction between import time and run time. As such, it’s possible to read settings at import time, but this can lead to subtle bugs. Reading a setting at import time will use or copy its initial value, and will not account for any later changes. Settings don’t often change, but when they do, you definitely want to use the new value. For example, take this views file: from django.conf import settings ... page_size = settings.PAGE_SIZE def book_list(request): paginator = Paginator(Book.objects.all(), page_size) ... page_size is set to the value of the setting once, at import time. It won’t account for any changes made in tests, such as with override_settings: from django.test import TestCase, override_settings class BookListTests(TestCase): def test_pagination(self): with override_settings(PAGE_SIZE=2): response = self.client.get(...) The previous view code would not use the changed PAGE_SIZE … -
