## Valores singulares no corpo

Assim como existem uma `Query` e uma `Path` para definir dados adicionais para parâmetros de consulta e de rota, o **FastAPI** provê o equivalente para `Body`.

Por exemplo, extendendo o modelo anterior, você poder decidir por ter uma outra chave `importance` no mesmo corpo, além de `item` e `user`.

spec:
  group: extensions.istio.io
  names:
    categories:
    - istio-io
    - extensions-istio-io
    kind: WasmPlugin
    listKind: WasmPluginList
    plural: wasmplugins
    singular: wasmplugin
  scope: Namespaced
  versions:
  - additionalPrinterColumns:
    - description: 'CreationTimestamp is a timestamp representing the server time

    `Optional[str]` の`Optional` はFastAPIでは使用されていません（FastAPIは`str`の部分のみ使用します）。しかし、`Optional[str]` はエディタがコードのエラーを見つけるのを助けてくれます。

## Pydanticを使わない方法

		joinFieldName := strings.Title(relation.FieldSchema.Name) + relField.Name

		if _, ok := ownFieldsMap[joinFieldName]; ok {
			if field.Name != relation.FieldSchema.Name {
				joinFieldName = inflection.Singular(field.Name) + relField.Name
			} else {
				joinFieldName += "Reference"
			}
		}

		if len(joinReferences) > idx {
			joinFieldName = strings.Title(joinReferences[idx])
		}

### `scope`

The spec also says that the client can send another form field "`scope`".

The form field name is `scope` (in singular), but it is actually a long string with "scopes" separated by spaces.

Each "scope" is just a string (without spaces).

They are normally used to declare specific security permissions, for example:

/third-party/ "Kotlin Compiler Core"

/wasm/ "Kotlin Wasm"

This isn't even Python, NestJS is a JavaScript (TypeScript) NodeJS framework inspired by Angular.

It achieves something somewhat similar to what can be done with Flask-apispec.

        collective. This parallelizes work on CPU and speeds up the collective
        performance. Default behavior is unchanged.
    *   Add an option `perturb_singular` to `tf.linalg.tridiagonal_solve` that
        allows solving linear systems with a numerically singular tridiagonal
        matrix, e.g. for use in inverse iteration.
    *   Added `tf.linalg.eigh_tridiagonal` that computes the eigenvalues of a

Це навіть не Python, NestJS — це фреймворк NodeJS JavaScript (TypeScript), натхненний Angular.

Це досягає чогось подібного до того, що можна зробити з Flask-apispec.

## Tipos especiais e validação

Além dos tipos singulares normais como `str`, `int`, `float`, etc. Você também pode usar tipos singulares mais complexos que herdam de `str`.
