```Python
q: Annotated[str, Query(default="rick")] = "morty"
```

... denn es ist nicht klar, ob der Defaultwert „rick“ oder „morty“ sein soll.

Sie würden also (bevorzugt) schreiben:

```Python
q: Annotated[str, Query()] = "rick"
```

... oder in älteren Codebasen finden Sie:

```Python
q: str = Query(default="rick")
```

```Python
q: Annotated[str, Query(default="rick")] = "morty"
```

...porque não está claro se o valor padrão deveria ser `"rick"` ou `"morty"`.

Então, você usaria (preferencialmente):

```Python
q: Annotated[str, Query()] = "rick"
```

...ou em bases de código mais antigas você encontrará:

```Python
q: str = Query(default="rick")
```

If a client tries to send some extra data, they will receive an **error** response.

For example, if the client tries to send the form fields:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

They will receive an error response telling them that the field `extra` is not allowed:

```json
{
    "detail": [
        {

Pydantic のモデル設定で、`extra` フィールドを `forbid` にできます:

{* ../../docs_src/request_form_models/tutorial002_an_py310.py hl[12] *}

クライアントが余分なデータを送信しようとすると、**エラー**のレスポンスを受け取ります。

例えば、クライアントが次のフォームフィールドを送ろうとした場合:

- `username`: `Rick`
- `password`: `Portal Gun`
- `extra`: `Mr. Poopybutthole`

フィールド `extra` は許可されていない旨のエラーレスポンスが返されます:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",

                .getOrElse('test_admin'),
        password: providers.systemProperty('tests.rest.cluster.password')
                .forUseAtConfigurationTime()
                .getOrElse('x-pack-test-password')
