You list a bunch of libraries, but Django is not a library. It is a framework.
The Django file structure, for example, is not exactly optional in Django. Realize FastAPI follows in the footsteps of Flask. Neither FastAPI or Flask are frameworks. As a FastAPI user myself, I do think it’s closer to a happy medium, but it’s nothing remotely comparable to Django.
When using Django, the best advice I have is to dive all the way in. Follow the docs and the best practices first. Besides, manage.py is just like having a well-developed kit of shell scripts/ in your repo.
You write views, and they render templates. There's a file called `urls.py` where you import a view and attach it to an actual url.
So
appconfig/urls.py depends on
yourapp/views.py which renders html using a template at
yourapp/templates/sometemplate.html
Presuming that you want to interact with the database `yourapp/views.py` probably also depends on models from `yourapp/models.py` or some other apps database model.
I can't grok it completely. All the books that I read on it skipped the architecture part.
Maybe there is a good guide to Django architecture - the big picture?
PS I am rather experienced in Python (Numpy, Pandas, Plotly, Flask, SQLAlchemy, FastAPI, BeautifulSoup are my bread and butter)
