這種情況下，你可以使用「自訂驗證函式」，它會在一般驗證之後套用（例如先確認值是 `str` 之後）。

你可以在 `Annotated` 中使用 [Pydantic 的 `AfterValidator`](https://docs.pydantic.dev/latest/concepts/validators/#field-after-validator) 來達成。

/// tip | 提示

Pydantic 也有 [`BeforeValidator`](https://docs.pydantic.dev/latest/concepts/validators/#field-before-validator) 等等。🤓

Deployment-related operations.
     * Behavior change:
        * Deployment creates ReplicaSets instead of ReplicationControllers.
        * Scale subresource now has a new <code>targetSelector</code> field in its status. This field supports the new set-based selectors supported
by Deployments, but in a serialized format.
     * Spec change:

- The CertificateSigningRequest `spec.expirationSeconds` API field has graduated to GA. The `CSRDuration` feature gate for the field is now unconditionally enabled and will be removed in 1.26. ([#108782](https://github.com/kubernetes/kubernetes/pull/108782), [@cfryanr](https://github.com/cfryanr)) [SIG API Machinery, Apps, Auth, Instrumentation and Testing]
