The same as when declaring query parameters, when a model attribute has a default value, it is not required. Otherwise, it is required. Use `None` to make it just optional.

For example, this model above declares a JSON "`object`" (or Python `dict`) like:

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

</div>

### Шаг 3: определите *операцию пути (path operation)*

#### Путь (path)

"Путь" это часть URL, после первого символа `/`, следующего за именем домена.

Для URL:

```
https://example.com/items/foo
```

...путь выглядит так:

```
/items/foo
```

/// info | "Дополнительная иформация"

Термин "path" также часто называется "endpoint" или "route".

///

and error rates are from the perspective of the service itself and not of an
individual client (or aggregate set of clients). Rates and latencies are
calculated over a time interval of 1 minute.
`,
		Example: `  # Retrieve workload metrics for productpage-v1 workload
  istioctl experimental metrics productpage-v1

  # Retrieve workload metrics for various services with custom duration

```

</div>

### 🔁 3️⃣: ✍ *➡ 🛠️*
