Here's my thought on 💭 python - Concepts of backref and back_populate in SQLalchemy? ...
Today I came across some sqlalchemy models that created some relationships, some used backref
some used back_populates. I was stumped why, I had never came accross backref before and I felt skill issues sinking in.
backref is considered legacy
https://docs.sqlalchemy.org/en/14/orm/backref.html
As stated in the sqlalchemy docs, backref is a legacy feature. Its shorthand to creating relationships between parent and child, but only adding it to the parent. While this is simpler it introduces some invisible magic.
