## Написание шаблонов { #writing-templates }

Затем вы можете создать шаблон в `templates/item.html`, например:

```jinja hl_lines="7"
{!../../docs_src/templates/templates/item.html!}
```

### Значения контекста шаблона { #template-context-values }

В HTML, который содержит:

{% raw %}

```jinja
Item ID: {{ id }}
```

{% endraw %}

### レスポンス結果

クライアントが`http://example.com/items/foo`（`item_id` `"foo"`）をリクエストすると、HTTPステータスコードが200で、以下のJSONレスポンスが返されます:

```JSON
{
  "item": "The Foo Wrestlers"
}
```

しかし、クライアントが`http://example.com/items/bar`（存在しない`item_id` `"bar"`）をリクエストした場合、HTTPステータスコード404（"not found"エラー）と以下のJSONレスポンスが返されます:

```JSON
{
  "detail": "Item not found"
}
```

#### Um item aleatório { #a-random-item }

Com `data.items()` obtemos um <abbr title="Algo que podemos iterar com um laço for, como uma list, set, etc.">objeto iterável</abbr> com tuplas contendo a chave e o valor de cada item do dicionário.

Convertimos esse objeto iterável em uma `list` adequada com `list(data.items())`.

## Another module with `APIRouter` { #another-module-with-apirouter }

Let's say you also have the endpoints dedicated to handling "items" from your application in the module at `app/routers/items.py`.

You have *path operations* for:

* `/items/`
* `/items/{item_id}`

It's all the same structure as with `app/routers/users.py`.

But we want to be smarter and simplify the code a bit.

Avec ce code, en allant sur :

```
http://127.0.0.1:8000/items/foo?short=1
```

ou

```
http://127.0.0.1:8000/items/foo?short=True
```

ou

```
http://127.0.0.1:8000/items/foo?short=true
```

ou

```
http://127.0.0.1:8000/items/foo?short=on
```

ou

```
http://127.0.0.1:8000/items/foo?short=yes
```

        return encoded_dict
    if isinstance(obj, (list, set, frozenset, GeneratorType, tuple, deque)):
        encoded_list = []
        for item in obj:
            encoded_list.append(
                jsonable_encoder(
                    item,
                    include=include,
                    exclude=exclude,
