How it works with real example (with bigger project structure)?

[michaldev]

In my case, I have problem with import everything from main file (with fastapi app object).
https://github.com/michaldev/problem-with-fastapi-import

Access to the app object is not required for other libraries.

I try like this:
main.py: socket_manager.attach(app=app)
sockets.py: socket_manager = SocketManager(app=None)

by returns AttributeError: 'NoneType' object has no attribute 'mount'

Solved. I used python-socketio instead of fastapi-socketio and I was able to connect a manager from main that is in a different file. This prevents circular imports.
