Support for Pydantic v2 #34

Open ctraizet opened 1 year ago

ctraizet commented 1 year ago

Pydantic v2 is now the default version of Pydantic packaged in pip (https://docs.pydantic.dev/latest/migration/#install-pydantic-v2), but pesto does not support this, as this import does not work : https://github.com/AirbusDefenceAndSpace/pesto/blob/0d4491bace0a2470afadc3b67ee34d17a02ca18f/pesto-cli/pesto/ws/config.py#L2

    return _getattr_migration(attr_name)
  File "/usr/local/lib/python3.8/site-packages/pydantic/_migration.py", line 279, in wrapper
    raise PydanticImportError(
pydantic.errors.PydanticImportError: `BaseSettings` has been moved to the `pydantic-settings` package. See https://docs.pydantic.dev/2.0.2/migration/#basesettings-has-moved-to-pydantic-settings for more details.

A current workaround is to use an old version of pydantic, which is still available in pip.

Pydantic V2 support in FastAPI is still in progress, until this done, it is better to stay in V1
