pydantic-sqlalchemy VS sqlmodel

The main benefit is actually being able to have statically typed models instead of dynamic, to get autocompletion, error checks, etc.

In fact, I made a small utility library some time ago to create dynamic Pydantic models from SQLAlchemy models (https://github.com/tiangolo/pydantic-sqlalchemy), but that's only useful in a few cases, e.g. for response_model in FastAPI.

Seems like this is a known bug in SQLModel: https://github.com/tiangolo/sqlmodel/issues/10

I have not used it myself but the creator of fastapi has made https://github.com/tiangolo/sqlmodel

I have already posted this question in Stack Overflow and GitHub and have been ignored in both 😢. You guys are my last hope.

I had a requirement to process and validate large payloads of JSON concurrently for a web service, initially I implemented it using jsonschema and fastjsonschema but I found the whole JSON Schema Specification to be confusing at times and on top of that wanted better performance. Albeit there are ways to compile/cache the schema, I wanted to move away from the schema specification so I wrote a validation library inspired by the design of tiangolo/sqlmodel (type hints) to solve this problem easier.

I would say as long as your current solution works and is easy to maintain keep it. If you want to switch I would recommend FastAPI, it is new(ish), but definitely old enough to have been tested and used in a large variety of production usecases. In your case it might be interesting to have a look at SQLModel (works with FastAPI, same author), especially if the API endpoints match closely to the database objects. https://github.com/tiangolo/sqlmodel

SQLModel.

Sounds similar to https://github.com/tiangolo/sqlmodel

There was a lot of hype and excitement around the release of SQLModel, a Pydantic + SQLAlchemy hybrid Model library with native integration for FastAPI. I pulled it out just now and there hasn't been any update beyond the initial anouncment on August 25th.
