## Recapitulando

Com `Query`, `Path` (e outras que você ainda não viu) você pode declarar metadados e validações de texto do mesmo modo que com [Parâmetros de consulta e validações de texto](query-params-str-validations.md){.internal-link target=_blank}.

E você também pode declarar validações numéricas:

* `gt`: maior que (`g`reater `t`han)
* `ge`: maior que ou igual (`g`reater than or `e`qual)
* `lt`: menor que (`l`ess `t`han)

Vous pouvez utiliser les `Enum`s de la même façon qu'avec les [Paramètres de chemin](path-params.md#valeurs-predefinies){.internal-link target=_blank}.

入力モデルがまだ検証されていることに注目してください。

そのため、すべての属性を省略できる部分的な変更を受け取りたい場合は、すべての属性をオプションとしてマークしたモデルを用意する必要があります（デフォルト値または`None`を使用して）。

**更新** のためのオプション値がすべて設定されているモデルと、**作成** のための必須値が設定されているモデルを区別するには、[追加モデル](extra-models.md){.internal-link target=_blank}で説明されている考え方を利用することができます。
