Теперь вы знаете, что когда они понадобятся, вы сможете использовать их в **FastAPI**.

### `regex` из Pydantic v1 вместо `pattern` { #pydantic-v1-regex-instead-of-pattern }

До Pydantic версии 2 и до FastAPI 0.100.0 этот параметр назывался `regex`, а не `pattern`, но сейчас он устарел.

Вы всё ещё можете встретить такой код:

//// tab | Pydantic v1

Agora você sabe que, sempre que precisar delas, pode usá-las no **FastAPI**.

### Pydantic v1 `regex` em vez de `pattern` { #pydantic-v1-regex-instead-of-pattern }

Antes da versão 2 do Pydantic e antes do FastAPI 0.100.0, o parâmetro se chamava `regex` em vez de `pattern`, mas agora está descontinuado.

Você ainda pode ver algum código usando isso:

//// tab | Pydantic v1

	queueDirComment   = `staging dir for undelivered messages e.g. '/home/events'`
	queueLimitComment = `maximum limit for undelivered messages, defaults to '100000'`
)

// Help template inputs for all notification targets
var (
	HelpWebhook = config.HelpKVS{
		config.HelpKV{
			Key:         target.WebhookEndpoint,

topologySpreadConstr: [] ## Add stateful containers to have security context, if enabled MinIO will run as this ## user and group NOTE: securityContext is only enabled if persistence.enabled=true securityContext: enabled: true runAsUser: 1000 runAsGroup: 1000 fsGroup: 1000 fsGroupChangePolicy: "OnRootMismatch" containerSecurityCon: readOnlyRootFilesyst: false # Additational pod annotations podAnnotations: {} # Additional pod labels podLabels: {} ## Configure resource requests and limits ## ref: http:/...

Але тепер Ви знаєте, що коли вони знадобляться, їх можна застосовувати у **FastAPI**.

### Pydantic v1 `regex` замість `pattern`

До версії Pydantic 2 і FastAPI 0.100.0 параметр називався `regex` замість `pattern`, але тепер він застарів.

Ви все ще можете зустріти код, який використовує його:

//// tab | Pydantic v1
