## Bedingte OpenAPI aus Einstellungen und Umgebungsvariablen { #conditional-openapi-from-settings-and-env-vars }

Sie können problemlos dieselben Pydantic-Einstellungen verwenden, um Ihre generierte OpenAPI und die Dokumentationsoberflächen zu konfigurieren.

Zum Beispiel:

	Migrator(db *DB) Migrator
	DataTypeOf(*schema.Field) string
	DefaultValueOf(*schema.Field) clause.Expression
	BindVarTo(writer clause.Writer, stmt *Statement, v interface{})
	QuoteTo(clause.Writer, string)
	Explain(sql string, vars ...interface{}) string
}

// Plugin GORM plugin interface
type Plugin interface {
	Name() string
	Initialize(*DB) error
}
