In this blog post I’ll talk about Django folders structure inside a project.
After developing a few projects with Django 1.11 and Django 2.0, I’ve stumbled with somewhat an issue that’s been bothering me. When you create projects and apps in Django, as the tutorial shows you, apps will be created inside the main project folder, at the same level of the project’s settings folder (usually it’s the folder that has the same name as your project).
So basically, what you end up with is a container folder and inside has the project config folder, and many other folders with the app names.
So as a result, you get different ordering in the folders for every new project, as folders will usually order by name inside your IDE, i.e PyCharm.
So, for instance, if your app is called ‘apples’ and your project is called ‘mysite’, then the order will be:
- apples - mysite
Let’s also assume you’re using docker, so you probably have a docker folder, now we have:
- apples - docker - mysite
But if you create an app called ‘oranges’, now your project folder is:
- apples - docker - mysite - oranges
This is unconfortable because you never know which is the project’s config folder and which ones are the different app folders, so you keep opening the wrong folders all the time!! This is awful, as programers, we tend strive for efficiency!! 🙂
So my strategy for now is to bundle all apps inside an apps folder, so my project will always look like:
- apps - docker - mysite
And there you have it, nicely ordered apps inside your project!!
To include them in your settings, you just have to remember to include the namespace
so if your app is called apples
INSTALLED_APPS += ['apps.apples']
Also, when importing classes in different files, just use the namespace.
So imagine we need to import the Apple class defined in my models inside my apples app, would do something like so:
from apps.apples.models import Apple
If you’ve read until here, it means you REALLY CARE about your project folder structure, so here’s a handy script I’ve created to start apps. It’s just a wrapper from the django startapp command, but it takes care of the apps folder, etc.
#!/usr/bin/env bash if [ "$1" == "-h" ]; then echo "This script will create an app inside the apps folder" echo "To use type the following line:" echo "bash start-app.sh app_name" echo "Replace app_name with the actual name for your app" elif [ "$1" != "" ]; then if [ ! -d "apps" ]; then mkdir apps touch apps/__init__.py fi mkdir apps/$1 if [ -f /.dockerenv ]; then python manage.py startapp $1 apps/$1 else docker-compose run django python manage.py startapp $1 apps/$1 fi echo "Success! The app $1 has been aded, don't forget to add INSTALLED_APPS += ['apps.$1'] in your project's settings.py" else echo "Error! One parameter is expected: app_name" fi
I call the file “start-app.sh”, so to use it just type
bash start-app.sh app_name
