## Escribiendo plantillas

Luego puedes escribir una plantilla en `templates/item.html` con, por ejemplo:

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

### Valores de Contexto de la Plantilla

En el HTML que contiene:

{% raw %}

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

{% endraw %}

...mostrará el `id` tomado del `dict` de "contexto" que pasaste:

    /**

Ainsi, `0.5` serait une valeur valide. Mais `0.0` ou `0` ne le serait pas.

Et la même chose pour <abbr title="less than"><code>lt</code></abbr>.

	// accordingly. Client receives a HTTP error for invalid/unsupported
	// signatures.

## Retorno Adicional com `model`

Você pode fornecer o parâmetro `responses` aos seus *decoradores de caminho*.

Este parâmetro recebe um `dict`, as chaves são os códigos de status para cada retorno, como por exemplo `200`, e os valores são um outro `dict` com a informação de cada um deles.

Cada um desses `dict` de retorno pode ter uma chave `model`, contendo um modelo do Pydantic, assim como o `response_model`.

	// modified time of the object expecting the response status to be http.StatusNotModified.
	c.Assert(response.StatusCode, http.StatusOK)
}

// TestHeadOnBucket - Validates response for HEAD on the bucket.
// HEAD request on the bucket validates the existence of the bucket.
func (s *TestSuiteCommon) TestHeadOnBucket(c *check) {
	// generate a random bucket name.
	bucketName := getRandomBucketName()
