Part-07 onwards needs some dependency updates

[chen-bowen]

Hi Chris,

Thank you so much creating this course. As I'm going through the material, I realize the dependencies installation now will have issues with the super old version of SQLAlchemy. I have personally updated the dependencies to make it work on my m2 mac, it would be good to update those dependencies in the repo for people to have the latest version of codebase. I could also help you do it if necessary.

Thanks,
Bowen

Bowen: Could you provide a list of what you did to get Part-07 onwards working on a Mac?
I am having similar issues in running prestart, either as a Bash script or Python script.

Thanks!

I solved my issue with prestart.sh not finding app.db.base by defining PYTHONPATH to point to the base of the Part-07 git repo:

export PYTHONPATH=$HOME/Codes/PythonScripts/FastAPI-tutorial/ultimate-fastapi-tutorial/part-07-database

Then Ifound that the Pydantic schema for UserCreate had full_name in app/db/init_db.py but was missing first_name and surname. Adding dummy values for those Optional attributes then allowed prestart.sh to run to completion without error.
