Örneğin, yukarıdaki model şu şekilde bir JSON "`object`" (veya Python `dict`) tanımlar:

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

...`description` ve `tax` opsiyonel olduğu için (default değerleri `None`), şu JSON "`object`" da geçerli olur:

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```

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

Mais si le client demande `http://example.com/items/bar` (un `item_id` inexistant « bar »), il recevra un code d'état HTTP 404 (l'erreur « not found ») et une réponse JSON :

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

/// tip | Astuce

                    // Filtering an array is NOT in place
                    result.acceptedApiChanges = result.acceptedApiChanges.filter((item, pos, ary) => (!pos || (JSON.stringify(item) != JSON.stringify(ary[pos - 1]))));
                    return result;
                }

///

## Mehrere Body-Parameter { #multiple-body-parameters }

Im vorherigen Beispiel erwarteten die *Pfadoperationen* einen JSON-Body mit den Attributen eines `Item`s, etwa:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

Aber Sie können auch mehrere Body-Parameter deklarieren, z. B. `item` und `user`:

///

## Multiple body parameters { #multiple-body-parameters }

In the previous example, the *path operations* would expect a JSON body with the attributes of an `Item`, like:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

But you can also declare multiple body parameters, e.g. `item` and `user`:

///

## About "Form Fields" { #about-form-fields }

The way HTML forms (`<form></form>`) sends the data to the server normally uses a "special" encoding for that data, it's different from JSON.

**FastAPI** will make sure to read that data from the right place instead of JSON.

## Atributos con listas de submodelos { #attributes-with-lists-of-submodels }

También puedes usar modelos Pydantic como subtipos de `list`, `set`, etc.:

{* ../../docs_src/body_nested_models/tutorial006_py310.py hl[18] *}

Esto esperará (convertirá, validará, documentará, etc.) un cuerpo JSON como:

```JSON hl_lines="11"
{
    "name": "Foo",
