• I added a very descriptive title here.
• I used the GitHub search to find a similar question and didn't find it.
• I searched the documentation, with the integrated search.
• I already searched in Google "How to X" and didn't find any information.
• I already read and followed all the tutorials in the docs and didn't find an answer.

Example Code

import re
import sqlmodel


ORCID_REGEX = re.compile(r"([\dX]{4}-[\dX]{4}-[\dX]{4}-[\dX]{4})")


class Author(sqlmodel.SQLModel, table=False):
	name: str = sqlmodel.Field(description="The name of the author.")

	orcid: Optional[str] = sqlmodel.Field(
		default=None,
		description="The author's ORCID iD, if available.",
		regex=r"([\dX]{4}-[\dX]{4}-[\dX]{4}-[\dX]{4})"
	)

	def __repr__(self) -> str:
		if self.orcid is None:
			return f"Author({self.name})"
		return f"Author({self.name}, orcid={self.orcid})"

	def __hash__(self) -> int:
		if self.orcid is not None:
			return hash(self.orcid)
		return hash(self.name)

	def __eq__(self, other, /) -> bool:
		if isinstance(other, str):
			return self.name == other
		elif not isinstance(other, self.__class__):
			return False
		if other.orcid is not None:
			return self.orcid == other.orcid
		return self.name == other.name

Description

Pydantic's Field changed the parameter name of regex to pattern, so the value given to regex isn't being used by Pydantic.
