I've wasted so many hours keeping API schemas and ORM models in sync on FastAPI projects.. how does it handle schema evolution on larger projects? Like if I rename a field or split a model into 2, does makemigrations detect that correctly or does it treat it as a drop + create?

Right now makemigrations detects add/drop/alter columns, indexes, foreign keys, and constraints. Rename is treated as drop + create, same as Django's default. Automatic rename detection is on the roadmap but not there yet. For now you'd edit the generated migration manually if you need a rename. Splitting a model into two would be detected as one dropped table and two new ones, so you'd also want to adjust that migration by hand to preserve data.
