* `Field(primary_key=True)` 告訴 SQLModel，`id` 是 SQL 資料庫中的「主鍵」。 （你可以在 SQLModel 文件中進一步了解 SQL 主鍵）

    注意：我們在主鍵欄位使用 `int | None`，這樣在 Python 程式碼中我們可以「在沒有 `id` 的情況下建立物件」（`id=None`），假設資料庫在儲存時會「自動產生」。SQLModel 瞭解資料庫會提供 `id`，並且在資料庫綱要中「將該欄位定義為非空的 `INTEGER`」。詳情請見 [SQLModel 文件：主鍵](https://sqlmodel.tiangolo.com/tutorial/create-db-and-table/#primary-key-id)。

* `Field(index=True)` 告訴 SQLModel 應為此欄位建立「SQL 索引」，以便在用此欄位過濾讀取資料時更快查詢。

   APPENDIX: How to apply the Apache License to your work.

      To apply the Apache License to your work, attach the following
      boilerplate notice, with the fields enclosed by brackets "[]"
      replaced with your own identifying information. (Don't include
      the brackets!)  The text should be enclosed in the appropriate
      comment syntax for the file format. We also recommend that a

            ],
            "msg": "value is not a valid integer",
            "type": "type_error.integer"
        }
    ]
}
```

将得到如下文本内容：

```
Validation errors:
Field: ('path', 'item_id'), Error: Input should be a valid integer, unable to parse string as an integer
