...必須のパラメータ `needy` を加えなかったので、以下の様なエラーが表示されます:

`needy` は必須のパラメータなので、URLにセットする必要があります:

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

You can achieve that using <a href="https://docs.pydantic.dev/latest/concepts/validators/#field-after-validator" class="external-link" target="_blank">Pydantic's `AfterValidator`</a> inside of `Annotated`.

/// tip

Pydantic also has <a href="https://docs.pydantic.dev/latest/concepts/validators/#field-before-validator" class="external-link" target="_blank">`BeforeValidator`</a> and others. 🤓

* `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.
