Önceki bölümde güvenlik sistemi (dependency injection sistemine dayanır) *path operation function*'a `str` olarak bir `token` veriyordu:

{* ../../docs_src/security/tutorial001_an_py310.py hl[12] *}

Ancak bu hâlâ pek kullanışlı değil.

Bize mevcut kullanıcıyı verecek şekilde düzenleyelim.

## Bir kullanıcı modeli oluşturun { #create-a-user-model }

Önce bir Pydantic kullanıcı modeli oluşturalım.

     * <pre>
     * Display parameters as parsed by Maven (in canonical form) and comparison result:
     * 1. 1.2.7 == 1.2.7
     *    1.2.7 &gt; 1.2-SNAPSHOT
     * 2. 1.2-SNAPSHOT == 1.2-snapshot
     * </pre>
     *
     * @param args the version strings to parse and compare. You can pass arbitrary number of version strings and always
     *             two adjacent will be compared.

У попередньому розділі система безпеки (яка базується на системі впровадження залежностей) передавала функції операції шляху `token` як `str`:

{* ../../docs_src/security/tutorial001_an_py310.py hl[12] *}

Але це ще не дуже корисно.

Зробімо так, щоб вона повертала поточного користувача.

## Створити модель користувача { #create-a-user-model }

Спочатку створімо модель користувача в Pydantic.
