Downstream Fixes

I, evokateur, will push fixes (mostly having to do with SqlAlchemy 2.0) that make the tests pass in chapter branches here.

I will keep the version of Python at 3.8. This will be good for sanity checks as I'm coding along in 3.12

Tests Passing Branches

• chapter_02_repository (works with SqlAlchemy 2.0)
• chapter_04_service_layer (ditto)
• master (SqlAlchemy pinned to <2 upstream, aha.)

Each chapter has its own branch which contains all the commits for that chapter, so it has the state that corresponds to the end of that chapter. If you want to try and code along with a chapter, you'll want to check out the branch for the previous chapter.

Branches for the exercises follow the convention {chapter_name}_exercise, eg https://github.com/cosmicpython/code/tree/chapter_04_service_layer_exercise

• docker with docker-compose
• for chapters 1 and 2, and optionally for the rest: a local python3.8 virtualenv

(this is only required from chapter 3 onwards)

make build make up # or make all # builds, brings containers up, runs tests

python3.8 -m venv .venv &&source .venv/bin/activate # or however you like to create virtualenvs

(I like to do it like this)

pyenv shell 3.8 python -m venv .venv source .venv/bin/activate 

# for chapter 1 pip install pytest # for chapter 2 pip install pytest sqlalchemy # for chapter 4+5 pip install -r requirements.txt # for chapter 6+ pip install -r requirements.txt pip install -e src/ 

make test# or, to run individual test types make unit-tests make integration-tests make e2e-tests # or, if you have a local virtualenv make up pytest tests/unit pytest tests/integration pytest tests/e2e

There are more useful commands in the makefile, have a look and try them out.
