How to swap out Pydantic-settings #182

Closed aitoehigie closed 11 months ago

aitoehigie commented 11 months ago

I am trying to use this template to create a FastAPI + Langchain project, however, Langchain only supports Pydantic < v2 while Pydantic-settings which is tightly coupled with Pydantic + FastAPI depends on Pydantic v2.0+.

Any tips on how to swap it out?

There's no way to swap pydantic version from cli, but this option exists.

Just clone the repo, add this line context.pydanticv1 = True here https://github.com/s3rius/FastAPI-template/blob/master/fastapi_template/__main__.py#L20, right before the actual generation.

I'll make an option later. Actually, you can make a PR that adds this option, I'd really appreciate this.
