OpenAPI 3.1 support

[Apakottur]

Thank you for this great project!

Would be awesome if OpenAPI 3.1 was supported in addition to OpenAPI 3.0.

It looks like openapi-pydantic is being used for the OpenAPI parsing, and that project has support for 3.1.

The OpenAPI schema I'm working with comes from Pydantic JSON schema, which is complying to version 3.1 but not 3.0.

Hi, I also ran into this issue; connecting to a server written in FastAPI (0.115.6) and the produced OpenAPI is in version 3.1.0. I tried some FastAPI 'hacks' to make it report other versions but this server seems to use OpenAPI v3.1.0 features.

A quick and dirty that worked for me, was to update openapi_pydantic to 0.5.1 and to change all the openapi_pydantic imports from from openapi_pydantic.v3.v3_0 import to from openapi_pydantic.v3 import.

# pyproject.toml
-openapi-pydantic = "^0.5.0"
+openapi-pydantic = "^0.5.1"

One example:

+++ b/src/openapi_python_generator/language_converters/python/generator.py
@@ -1,6 +1,6 @@
 from typing import Optional
 
-from openapi_pydantic.v3.v3_0 import OpenAPI
+from openapi_pydantic.v3 import OpenAPI

• I did a blanked search and replace on the import.
• Tried the upgrade of openapi_pydantic first so I do not know if that is needed.
• Although this solved my issue it does not resolve error with Swagger Editor petstore example #63.

And thank you for openapi-python-generator, it is useful and works well.

@martinslabber this is absolutely possible. However, by doing that you remove 3.0 support - and sadly (afaik) 3.1 is not fully backwards compatible and introduced some breaking changes. I'll take a look though

I had tried on several API and most of them are OpenAPI 3.1 only - so this beautiful library is not working. Can you look into this?

Any updates?

I opened a PR to implement OpenAPI 3.1 support. I really like the approach this generator takes vs. the other ones I have found, but was blocked by lack of 3.1 support. Let me know what you think and hopefully we can get it merged and released soon!
