[iliakur]

I'm starting with just one method conversion to get initial feedback and check tests, but there's also one lurking in types.py which I'll convert later in the same PR.

Thank you for creating PR.
Could you please add the condition of PYDANIC_V2 ?
Because, we should support v1 in runtime yet.

datamodel-code-generator/datamodel_code_generator/parser/jsonschema.py

Lines 164 to 175 in 24bb074

	if PYDANTIC_V2:
	@classmethod
	def get_fields(cls) -> Dict[str, Any]:
	return cls.model_fields
	else:
	@classmethod
	def get_fields(cls) -> Dict[str, Any]:
	return cls.__fields__
