## Офіційний посібник { #official-guide }

У Pydantic є офіційний [Посібник з міграції](https://docs.pydantic.dev/latest/migration/) з v1 на v2.

Там описано, що змінилося, як перевірки тепер стали коректнішими та суворішими, можливі застереження тощо.

XML response for this API is similar to [AWS STS AssumeRoleWithWebIdentity](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRoleWithWebIdentity.html#API_AssumeRoleWithWebIdentity_ResponseElements)

如果你的舊 FastAPI 應用仍使用 Pydantic v1，這裡會示範如何遷移到 Pydantic v2，並介紹 **FastAPI 0.119.0** 中可協助你逐步遷移的功能。

## 官方指南 { #official-guide }

Pydantic 提供從 v1 遷移到 v2 的官方[遷移指南](https://docs.pydantic.dev/latest/migration/)。

其中包含變更內容、驗證如何更正確且更嚴格、可能的注意事項等。

你可以先閱讀以更好理解具體變更。

## 測試 { #tests }

確保你的應用有[測試](../tutorial/testing.md)，並在 CI（持續整合）上執行。

如此一來，你可以升級後確認一切仍如預期運作。

## `bump-pydantic` { #bump-pydantic }

	// Indicates whether MinIO will remove all versions. If set to true, all versions will be deleted;
	// if set to false the policy takes no action. This action uses the Days/Date to expire objects.
	// This check is verified for latest version of the object.
	DeleteAll Boolean `xml:"ExpiredObjectAllVersions"`

	set bool
}

// MarshalXML encodes delete marker boolean into an XML form.

To do that, use the standard Python type hint [`typing.Union`](https://docs.python.org/3/library/typing.html#typing.Union):

/// note

When defining a [`Union`](https://docs.pydantic.dev/latest/concepts/types/#unions), include the most specific type first, followed by the less specific type. In the example below, the more specific `PlaneItem` comes before `CarItem` in `Union[PlaneItem, CarItem]`.

Para ver todas as opções possíveis, consulte a [Visão geral dos tipos do Pydantic](https://docs.pydantic.dev/latest/concepts/types/). Você verá alguns exemplos no próximo capítulo.

Por exemplo, no modelo `Image` nós temos um campo `url`, nós podemos declará-lo como um `HttpUrl` do Pydantic invés de como uma `str`:

// Supported status types
const (
	Enabled  Status = "Enabled"
	Disabled Status = "Disabled"
)

// DeleteMarkerReplication - whether delete markers are replicated - https://docs.aws.amazon.com/AmazonS3/latest/dev/replication-add-config.html
type DeleteMarkerReplication struct {
	Status Status `xml:"Status"` // should be set to "Disabled" by default
}

// IsEmpty returns true if DeleteMarkerReplication is not set

}

// Unused. Available for completion.
type topic struct {
	ARN string `xml:"Topic" json:"Topic"`
}

// Config - notification configuration described in
// http://docs.aws.amazon.com/AmazonS3/latest/dev/NotificationHowTo.html
type Config struct {
	XMLNS      string   `xml:"xmlns,attr,omitempty"`
	XMLName    xml.Name `xml:"NotificationConfiguration"`
	QueueList  []Queue  `xml:"QueueConfiguration,omitempty"`
