Hello. I really liked this book, it gives a fresh (for me) perspective at coding a web application, and it looks fantastic, very well written, not too difficult to understand. I finished the part 1 a couple of hours ago, it turned my perspective upside down, and I decided to give my new knowledge a try, just writing a small web service. And I encountered a problem: if I want to use pydantic to write my domain models, when I apply the SQLAlchemy mapper on them, the models stop working, they simply throw error at initializing. I really love pydantic, but I also ain't sure it's worth implementing smth like in django appendix just because I wanna use pydantic insteadof dataclasses and just classes.

The error:
AttributeError: 'User' object has no attribute 'pydantic_private'. Did you mean: 'pydantic_complete'?
