This would allow you to **re-use the model** in **multiple places** and also to declare validations and metadata for all the parameters at once. 😎

## Query Parameters with a Pydantic Model { #query-parameters-with-a-pydantic-model }

`secrets.compare_digest()`; `bytes` ya da yalnızca ASCII karakterleri (İngilizce’deki karakterler) içeren bir `str` almalıdır. Bu da `Sebastián` içindeki `á` gibi karakterlerle çalışmayacağı anlamına gelir.

Bunu yönetmek için önce `username` ve `password` değerlerini UTF-8 ile encode ederek `bytes`’a dönüştürürüz.

- Once object lock configuration is set to a bucket
  - New objects inherit the retention settings of the bucket object lock configuration automatically
  - Retention headers can be optionally set while uploading objects
  - Once objects are uploaded PutObjectRetention API can be called to change retention settings
