# Body – Felder { #body-fields }

So wie Sie zusätzliche Validierung und Metadaten in Parametern der *Pfadoperation-Funktion* mittels `Query`, `Path` und `Body` deklarieren, können Sie auch innerhalb von Pydantic-Modellen zusätzliche Validierung und Metadaten deklarieren, mittels Pydantics `Field`.

## `Field` importieren { #import-field }

Importieren Sie es zuerst:

        final FtpAuthentication[] ftpAuthentications =
                getInitParameter(FTP_AUTHENTICATIONS_PROPERTY, new FtpAuthentication[0], FtpAuthentication[].class);

	EnvCompressExtensionsLegacy      = "MINIO_COMPRESS_EXTENSIONS"

// SetCompressionConfig - One time migration code needed, for migrating from older config to new for Compression.
func SetCompressionConfig(s config.Config, cfg Config) {

	}

Sie können die Modellkonfiguration von Pydantic verwenden, um jegliche `extra` Felder zu `verbieten`:

    that empty artifact over the "real" listenablefuture-1.0 -- avoiding a
    conflict with the copy of ListenableFuture in guava itself. If users are
    using an older version of Guava or a build system other than Gradle, they
    may see class conflicts. If so, they can solve them by manually excluding
    the listenablefuture artifact or manually forcing their build systems to
    use 9999.0-....
