Let's set aside the horrendous readability this creates down the line. functioning?Īs the Flask docs promise, your app's config can be modified as we did above and can be modified/changed at any time. For instance, why would we wait until after we create the Flask app object to set something as important as FLASK_ENV? Isn't the point of configuration to inform our app on how to function before it starts. Surely nobody who is clicking into "How To Do This Sensational Thing in Flask" tutorials care to learn best software development practices, which encourages a lot of bad behavior and leaves many questions unanswered. Stop me if you've seen something like this before:Įnter fullscreen mode Exit fullscreen mode app.pyįrom the perspective of an author writing tutorials for strangers, it's convenient to pretend that setting config values this way is acceptable. Amongst tutorials, it also seems to be the most common. The fastest, dirtiest, and most dangerous method for configuring Flask is by directly setting config vars in source code using plain text. Today we're covering two topics in Flask configuration: best practices in configuration structure and configuration settings themselves. Instead, we can choose to configure Flask via several methods. Unlike Django, there's no monolithic settings.py file in Flask (thank god). From my perspective, it's like watching a generation of grown professionals postponing their child's potty-training by one more day: both cases ultimately end with grown adults shitting their pants.Įvery web app needs to be configured with things like database URIs and secret keys to enable critical functionality. This level of short-term procrastination seems harmless to the untrained eye. I believe the cliche that the hardest part of anything is getting started, so it's no surprise that Flaks can get the imagination brewing.Ĭonfiguring apps isn't the sexiest topic to cover in the realm of hot new frameworks, which is precisely why most newcomers skip over this aspect of Flask development entirely. Discovering Flask is to rediscover instant gratification itself: all it takes is a mere few seconds for anybody to deploy a Python application, alive and well on a development server. The software industry has seen no shortage of new web frameworks over the years, but I certainly wouldn't be alone in saying that none.
