KNT but in django
Recommend checking out the django tutorial. The tutorial has cool commands on how to actually work with django, but a short recap here anyway.
Setup
To create the initial DB just run python manage.py migrate in the root directory.
To create a superuser run python manage.py createsuperuser, and follow the instructions.
After that you can start the server with python manage.py runserver.
Head over to the admin panel at localhost:8000/admin and login with the superuser credentials you have entered.
There you will find a handy panel to manually manage the database.
Create users, products, view transactions etc all nicely in one place.
You can also enter a nice handy shell with python manage.py shell, where you get an interactive python console with all the models loaded.
Development
If you find yourself in the need of editing the model schema, you can do so in knt_backend/models.py.
After that you need to run python manage.py makemigrations to create the migration files.
Then run python manage.py migrate to actually apply the changes to the database.
Useful routes are located in knt_backend/urls.py. They actually just point to some functions over in knt_backend/views.py.
If you wanna add a route, create a function there, and don't forget to register it in knt_backend/urls.py.
