* `Field(primary_key=True)`는 SQLModel에 `id`가 SQL 데이터베이스의 **기본 키**임을 알려줍니다 (SQL 기본 키에 대한 자세한 내용은 SQLModel 문서를 참고하세요).

    `int | None` 유형으로 설정하면, SQLModel은 해당 열이 SQL 데이터베이스에서 `INTEGER` 유형이며 `NULLABLE` 값이어야 한다는 것을 알 수 있습니다.

* `Field(index=True)`는 SQLModel에 해당 열에 대해 **SQL 인덱스**를 생성하도록 지시합니다. 이를 통해 데이터베이스에서 이 열으로 필터링된 데이터를 읽을 때 더 빠르게 조회할 수 있습니다.

can now store only `null` when created using the protobuf content-type or stored in etcd using protobuf serialization (the default in 1.6).
JSON API clients should tolerate `null` values for such fields, and treat `null` and `[]` as equivalent in meaning unless specifically documented otherwise for a particular field. ([#44593](https://github.com/kubernetes/kubernetes/pull/44593))

For example, given the Go declaration <code>const bufSize =
1024</code>, assembly code can refer to the value of this constant
as <code>const_bufSize</code>.
</p>

<p>
Field offsets are of the form <code><i>type</i>_<i>field</i></code>.
Struct sizes are of the form <code><i>type</i>__size</code>.
For example, consider the following Go definition:
</p>

<pre>
type reader struct {
	buf [bufSize]byte

Sie können dieselben Validierungs-Funktionen und -Tools verwenden, die Sie für Pydantic-Modelle verwenden, z. B. verschiedene Datentypen und zusätzliche Validierungen mit `Field()`.
