흔히 이렇게 알고 있다

Pydantic models validate and coerce all field defaults against annotated types and constraints during default instantiation.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• Leaving validate_default unset defaults to False: uncoerced string defaults remain raw strings and constraint-violating defaults are assigned directly without validation errors.
• Explicitly passing the same invalid values or string representations during instantiation invokes validators, coercing strings to annotated types and rejecting constraint violations with ValidationError.
• Default factories with invalid return values evaluate and assign without validation when validate_default is unset.
• Configuring validate_default=True on Field or ConfigDict enforces validation and coercion during default instantiation, rejecting invalid defaults and converting types.
