instead of:

        @app.get("/items/{id}")
        def read_items(id: tuple[Item, Item]):
            pass  # pragma: no cover

Тож фрагмент:

{% raw %}

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

{% endraw %}

...згенерує посилання на той самий URL, який оброблятиме *функція операції шляху* `read_item(id=id)`.

Наприклад, з ID `42` це буде відображено як:

```html
<a href="/items/42">
```

    ):

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)`.

Por ejemplo, con un ID de `42`, esto se renderizaría como:

```html
<a href="/items/42">
```
