Briefing a Delegate
Some managers think delegation is easy: you just ask someone on your team to go do a thing, then kick back with your feet on the desk until it’s done. Not true: delegating that way is a recipe for failure. To delegate effectively, you need to set up your delegate for success. This means explaining the work and desired outcomes, providing context, and teaching your delegate any skills they’ll need to be successful. -
How to load a Service Worker in Django
A service worker, part of the family of web workers, is, to put it shortly, a particular type of JavaScript code which can run off the main thread of execution. This has a number of benefits. In particular, service workers make possible to augment web applications with offline capabilities, and fine-grained cache management. In this brief post we see how to load a service worker in Django. The shortest introduction ever to service workers To put it simply, a service worker is like a proxy sitting in between the network and the web application. How to use a service worker? In its simplest form, we can load a service worker from any web page of the application, as in the following example: // Place this preferably in your app entry point: if ("serviceWorker" in navigator) { window.addEventListener("load", () => { navigator.serviceWorker .register("/service-worker.js") .then(registration => console.log("Service worker registered", registration) ) .catch(err => console.log(err)); }); } Here we check that the browser supports service workers, and we wait for the load DOM event before triggering the service worker registration: // navigator.serviceWorker .register("/service-worker.js") // This snippet is really important, and we can notice that we load our service worker from the root of … -

Cloning a Single Production Database Table from Heroku to Local Database with PostgreSQL in Docker Compose
I have a few Django apps in a Django project. I used factory_boy to mock a bunch of the data, but I have a few hundred rows of accurate data in my production database. It made sense to work on a copy of that data as it contains no sensitive user information. My project is hosted on Heroku with one of their free tier PostgreSQL databases. My local environment is a Docker Compose stack with images for Python, PostgreSQL, and Redis. The trickiest part here, in my opinion, is finding out just how to get the backup to the PostgreSQL docker container. Table of Contents Table of Contents Backup the Production Database Clone to Local Database Conclusion Backup the Production Database There are two easy ways to do this on Heroku Use the Heroku CLI Use the Heroku web interface The Heroku docs detail how to make a backup. Use the Heroku CLI to Backup Database So first, if you aren’t already using it, you’ll need to install the Heroku CLI and run heroku login. Next, you’ll need to know your app’s name in Heroku. Mine is mastering-fitness, but you can get a list of all your Heroku apps right … -
People- vs Results-Oriented Management: Both Work!
Broadly speaking, there are two management styles: people-oriented and results-oriented management. Taken to extremes both styles have failure modes, but seeking “balance” isn’t the answer. Both modes can be successful! Embrace the style that comes easiest to you, while learning enough about the other mode to avoid pitfalls. -
How to keep all your websites in sync with scraping technology
Would you like to pull in the header and/or footer from a related but separate website for use on your own pages? Here's how. Introduction Many of our clients maintain multiple websites, or multiple domains within a single website. For example, "store.example.com" and "www.example.com" will almost always be different websites. In many instances, the different websites are maintained by different vendors; however, most have at least some elements in common, such as logos, headers, footers, etc. Often, when deploying a new site, these shared elements are simply copied and pasted from the main site. This is quick and easy to do, but the downside of this approach is that when someone inevitably changes a logo or other shared element on the main site, the element that should be universal across both sites will go out of sync. Such "quiet" errors might go unnoticed for long stretches of time. When they are noticed, it might take some digging to figure out what changed and whether any other websites or subdomains have been affected. How often does this happen? Doing a quick Google search of "store." yielded store.playstation.com. Here's a screenshot of the footer of store.playstation.com and playstation.com: store.playstation.com www.playstation.com Now, these two … -

Introducing django-upgrade, a tool for upgrading your Django projects
Django deprecates a small list of features with every feature release, requiring us to update our projects, which can be monotonous. Today I’m announcing a new tool I’ve created, django-upgrade, that automates some of this drudgery for us all. The Story¶ For a while I’ve enjoyed using pyupgrade, which upgrades Python syntax to the latest and greatest. pyupgrade is both fast and accurate, what you’d hope for in such a tool. The idea is to run it continuously, via pre-commit or similar, so that any new usage of old syntax you add gets automatically upgraded. Last year, after a django-developers discussion, Bruno Alla created a similar tool for upgrading Django projects called django-codemod. django-codemod works well, and I’ve enjoyed running it on a few projects, saving me hours of boring find-and-replace. The only downside is that it’s relatively slow, taking up to several minutes on a medium sized project. This makes it okay for one-off runs, but it’s not suitable for running continuously (except on CI). django-codemod’s slowness is due to the underlying library, LibCST, which implements its parser in Python. In contrast, pyupgrade is fast because it uses Python’s own C-based parser. LibCST also comes with compatibility concerns - … -
User File Use

We also looked at tools to help you to be extra effective with settings. With this article, we’re going to dig into file management. Unlike the static files that you create for the app yourself, you may want your app to accept files from your users. Profile pictures are a good example of user files. -
