## 在 `q` 参数的类型中使用 `Annotated` { #use-annotated-in-the-type-for-the-q-parameter }

还记得我之前在[Python 类型简介](../python-types.md#type-hints-with-metadata-annotations)中说过可以用 `Annotated` 给参数添加元数据吗？

现在正是与 FastAPI 搭配使用它的时候。🚀

我们之前的类型标注是：

```Python
q: str | None = None
```

我们要做的是用 `Annotated` 把它包起来，变成：

```Python
q: Annotated[str | None] = None

            Human-readable title.

            Read more about it in the
            [FastAPI docs for Path Parameters and Numeric Validations](https://fastapi.tiangolo.com/tutorial/path-params-numeric-validations/#declare-metadata)
            """
        ),
    ] = None,
    description: Annotated[
        str | None,
        Doc(
            """
            Human-readable description.
            """
        ),
    ] = None,

In contrast to a "**container image**" that is the stored static contents, a "**container**" normally refers to the running instance, the thing that is being **executed**.

	}
	return *resp, nil
}

// LoadBucketMetadata - load bucket metadata
func (client *peerRESTClient) LoadBucketMetadata(ctx context.Context, bucket string) error {
	_, err := loadBucketMetadataRPC.Call(ctx, client.gridConn(), grid.NewMSSWith(map[string]string{
		peerRESTBucket: bucket,
	}))
	return err
}

// DeleteBucketMetadata - Delete bucket metadata

	// Extract all the signed headers along with its values.
	extractedSignedHeaders, errCode := extractSignedHeaders(pSignValues.SignedHeaders, r)
	if errCode != ErrNone {
		return errCode
	}

	// Check if the metadata headers are equal with signedheaders
	errMetaCode := checkMetaHeaders(extractedSignedHeaders, r)
	if errMetaCode != ErrNone {
		return errMetaCode
	}

古いバージョンの場合、`Annotated`を使おうとするとエラーになります。

`Annotated`を使用する前に、FastAPI のバージョンを少なくとも 0.95.1 まで[アップグレードしてください](../deployment/versions.md#upgrading-the-fastapi-versions)。

## メタデータの宣言 { #declare-metadata }

パラメータは`Query`と同じものを宣言することができます。

例えば、パスパラメータ`item_id`に対して`title`のメタデータを宣言するには以下のようにします:

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[10] *}

/// note | 備考

- The rules for incrementing `metadata.generation` of custom resources changed: ([#69059](https://github.com/kubernetes/kubernetes/pull/69059), [@caesarxuchao](https://github.com/caesarxuchao))
  - If the custom resource participates the spec/status convention, the metadata.generation of the CR increments when there is any change, except for the changes to the metadata or the changes to the status.

        byte[] serialized1 = serializer.fromObjectToBinary(original);
        byte[] serialized2 = serializer.fromObjectToBinary(original);

        // Note: Serialized bytes may not be identical due to metadata,
        // but deserialization should produce the same result
        Object deserialized1 = serializer.fromBinaryToObject(serialized1);
        Object deserialized2 = serializer.fromBinaryToObject(serialized2);

## `q` パラメータの型で `Annotated` を使う { #use-annotated-in-the-type-for-the-q-parameter }

以前、[Python Types Intro](../python-types.md#type-hints-with-metadata-annotations) で `Annotated` を使ってパラメータにメタデータを追加できると説明したことを覚えていますか？

いよいよ FastAPI で使うときです。 🚀

次の型アノテーションがありました:

```Python
q: str | None = None
```

これを `Annotated` で包んで、次のようにします:

```Python
