In this post I present my latest project template for Python projects, copier-pdm, based on the great Copier.
This parodic title was inspired by the "Hypermodern Python" article series by Claudio Jolowicz. Indeed, my Python development setup has parts that could considered modern by some, and old-school by others, so I found it funny to call it "more-or-less modern".
In the previous post I showed how to add Alembic migrations to an existing FastAPI + Ormar project. In this post we will see how to write unit tests for such applications.
I had trouble adding an ON DELETE CASCADE constraint to foreign keys after they were already created, so here's a small post explaning how I did it. This specific constraint, ON DELETE CASCADE, is not relevant here. This post will help you for any kind of change you want to apply on database already used in production.
