pydantic v2 support #530

Open DeoLeung opened 9 months ago

Hi,

Thanks for the great job. I'm just wondering whether pydantic v2 support is on the way, seems using root_validator is raising error in v2.

like langchain use a submodule import .

One of the commits in #531 limits Pydantic to v1 to fix this issue. I noticed that popping up more consistently during tests with the Tox fix - not entirely sure why it wasn't being flagged before.

Hi all, is there any update on this? I would love to use betterproto, but I can not switch back to pydantic v1.

Thanks

Maybe I'm wrong but I don't think limiting pydantic to an outdated version is an ideal solution to this issue. Is this the only problem with using pydantic > 2? The error message I get indicates that you just need to specify skip_on_failure=True in the root_validator decorator (which should be replaced with model_validator either way). Would you accept a PR that makes that change?
