Aquí definimos la configuración `env_file` dentro de tu clase Pydantic `Settings`, y establecemos el valor en el nombre del archivo con el archivo dotenv que queremos usar.

### Creando el `Settings` solo una vez con `lru_cache` { #creating-the-settings-only-once-with-lru-cache }

	DB.Table("langs").Migrator().DropTable(&Language{})
	DB.Table("langs").AutoMigrate(&Language{})

	if err := DB.Table("langs").Save(&lang).Error; err != nil {
		t.Errorf("no error should happen when creating data, but got %v", err)
	}

	var result3 Language
	if err := DB.Table("langs").First(&result3, "code = ?", lang.Code).Error; err != nil || result3.Name != lang.Name {

	for i := 0; i < nFiles; i++ {
		_, err := w.CreateHeader(&FileHeader{
			Name:   fmt.Sprintf("%d.dat", i),
			Method: Store, // Deflate is too slow when it is compiled with -race flag
		})
		if err != nil {
			t.Fatalf("creating file %d: %v", i, err)
		}
	}
	if err := w.Close(); err != nil {
		t.Fatalf("Writer.Close: %v", err)
	}
	s := buf.String()
	zr, err := NewReader(strings.NewReader(s), int64(len(s)))
	if err != nil {

Здесь мы задаем параметр конфигурации `env_file` внутри вашего класса Pydantic `Settings` и устанавливаем значение равным имени файла dotenv, который хотим использовать.

### Создание `Settings` только один раз с помощью `lru_cache` { #creating-the-settings-only-once-with-lru-cache }

			// permission to alter the retention settings or delete the object
			// if necessary. You can also use governance mode to test retention-period
			// settings before creating a compliance-mode retention period.
			// To override or remove governance-mode retention settings, a
			// user must have the s3:BypassGovernanceRetention permission

All corresponding variables will be ignored in values file.

### Configure TLS

You can use the same type declarations with `str`, `float`, `bool` and many other complex data types.

Several of these are explored in the next chapters of the tutorial.

## Order matters { #order-matters }

When creating *path operations*, you can find situations where you have a fixed path.

Like `/users/me`, let's say that it's to get data about the current user.

 *     [chunked][newChunkedSource] or [unknown][newUnknownLengthSource].
 *  6. Read from and close that source.
 *
 * Exchanges that do not have a request body may skip creating and closing the request body.
 * Exchanges that do not have a response body can call
 * [newFixedLengthSource(0)][newFixedLengthSource] and may skip reading and closing that source.

Hier definieren wir die Konfiguration `env_file` innerhalb Ihrer Pydantic-`Settings`-Klasse und setzen den Wert auf den Dateinamen mit der dotenv-Datei, die wir verwenden möchten.

### Die `Settings` nur einmal laden mittels `lru_cache` { #creating-the-settings-only-once-with-lru-cache }
