若要查看所有可用選項，請參閱 [Pydantic 的型別總覽](https://docs.pydantic.dev/latest/concepts/types/)。你會在下一章看到一些範例。

例如，在 `Image` 模型中有一個 `url` 欄位，我們可以將其宣告為 Pydantic 的 `HttpUrl`，而不是 `str`：

{* ../../docs_src/body_nested_models/tutorial005_py310.py hl[2,8] *}

該字串會被檢查是否為有效的 URL，並在 JSON Schema / OpenAPI 中相應註記。

## 具有子模型列表的屬性 { #attributes-with-lists-of-submodels }

你也可以將 Pydantic 模型作為 `list`、`set` 等的子型別使用：

{* ../../docs_src/security/tutorial001_an_py310.py hl[8] *}

/// tip | Порада

Тут `tokenUrl="token"` відноситься до відносної URL-адреси `token`, яку ми ще не створили. Оскільки це відносна URL-адреса, вона еквівалентна `./token`.

```

### Argumentos de la Plantilla `url_for` { #template-url-for-arguments }

También puedes usar `url_for()` dentro de la plantilla, toma como argumentos los mismos que usaría tu *path operation function*.

Entonces, la sección con:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

...generará un enlace hacia la misma URL que manejaría la *path operation function* `read_item(id=id)`.

 * It converts Unicode domain names to ASCII Compatible Encoding (ACE) using the
 * {@link java.net.IDN} class.
 *
 * <p>This class allows setting a custom flag for the IDN conversion and a custom
 * encoding for URL decoding.</p>
 *
 * <p>Example usage:</p>
 * <pre>
 * {@code
 * IdnDnsResolver resolver = new IdnDnsResolver();
 * resolver.setFlag(IDN.ALLOW_UNASSIGNED);
 * resolver.setEncoding("UTF-8");
