### Partial updates recap { #partial-updates-recap }

In summary, to apply partial updates you would:

* (Optionally) use `PATCH` instead of `PUT`.
* Retrieve the stored data.
* Put that data in a Pydantic model.

        String result = Hexdump.toHexString(data);
        assertEquals(2048, result.length()); // 1024 bytes * 2 chars

        // Test partial conversion
        String partial = Hexdump.toHexString(data, 512, 256);
        assertEquals(512, partial.length()); // 256 bytes * 2 chars
        assertTrue(partial.startsWith("00010203")); // 512 % 256 = 0, so starts at 0
    }

    "price": 3,
    "description": None,
}
```

이미 저장된 속성 `"tax": 20.2`가 포함되어 있지 않기 때문에, 입력 모델은 `"tax": 10.5`라는 기본값을 사용하게 됩니다.

그리고 데이터는 그 “새로운” `tax` 값 `10.5`로 저장됩니다.

## `PATCH`로 부분 업데이트하기 { #partial-updates-with-patch }

[HTTP `PATCH`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PATCH) 작업을 사용해 데이터를 *부분적으로* 업데이트할 수도 있습니다.

이는 업데이트하려는 데이터만 보내고, 나머지는 그대로 두는 것을 의미합니다.

/// note | 참고

	testCases := []struct {
		name         string
		statusCode   int
		body         string
		contentType  string
		expectStatus int
	}{
		{
			name:         "Success 206 Partial Content",
			statusCode:   206,
			body:         "partial-object-data",
			contentType:  "text/plain",
			expectStatus: 206,
		},
		{
			name:         "Success 200 OK",
			statusCode:   200,
			body:         "full-object-data",

 * <ol>
 * <li>success - in which case only the model field is set
 * <li>success with warnings - model field + non-error model problems
 * <li>error - no model, but diagnostics
 * <li>error - (partial) model and diagnostics
 * </ol>
 * Could encode these variants as subclasses, but kept in one for now
 *
 * @param <T> the model type
 * @deprecated use {@code org.apache.maven.api.services.ModelBuilder} instead

    "price": 3,
    "description": None,
}
```

由於這裡沒有包含已儲存的屬性 `"tax": 20.2`，輸入的模型會採用預設值 `"tax": 10.5`。

最終資料會以這個「新的」 `tax` 值 `10.5` 被儲存。

## 使用 `PATCH` 進行部分更新 { #partial-updates-with-patch }

你也可以使用 [HTTP `PATCH`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PATCH) 操作來進行*部分*更新。

這表示你只需傳送想要更新的資料，其餘保持不變。

/// note | 注意

`PATCH` 相較於 `PUT` 較少被使用、也較不為人知。
