Zum Beispiel deklariert das obige Modell ein JSON "`object`" (oder Python-`dict`) wie dieses:

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

Da `description` und `tax` optional sind (mit `None` als Defaultwert), wäre folgendes JSON "`object`" auch gültig:

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```

* Він має <a href="https://docs.python.org/3/glossary.html#term-file-like-object" class="external-link" target="_blank">file-like</a> `асинхронний файловий інтерфейс` interface.

We also declare a special parameter of type `SecurityScopes`, imported from `fastapi.security`.

This `SecurityScopes` class is similar to `Request` (`Request` was used to get the request object directly).

{* ../../docs_src/security/tutorial005_an_py310.py hl[9,106] *}

## Use the `scopes` { #use-the-scopes }

The parameter `security_scopes` will be of type `SecurityScopes`.

**FastAPI** 完全相容且基於 <a href="https://docs.pydantic.dev/" class="external-link" target="_blank"><strong>Pydantic</strong></a>。所以，你有其他 Pydantic 程式碼也能正常工作。

相容包括基於 Pydantic 的外部函式庫， 例如用於資料庫的 <abbr title="Object-Relational Mapper">ORM</abbr>s, <abbr title="Object-Document Mapper">ODM</abbr>s。

這也意味著在很多情況下，你可以把從請求中獲得的物件**直接傳到資料庫**，因為所有資料都會自動進行驗證。

反之亦然，在很多情況下，你也可以把從資料庫中獲取的物件**直接傳給客戶端**。
