## 减少重复 { #reduce-duplication }

减少代码重复是 **FastAPI** 的核心思想之一。

代码重复会导致 bug、安全问题、代码失步等问题（更新了某个位置的代码，但没有同步更新其它位置的代码）。

上面的这些模型共享了大量数据，拥有重复的属性名和类型。

我们可以做得更好。

声明 `UserBase` 模型作为其它模型的基类。然后，用该类衍生出继承其属性（类型声明、校验等）的子类。

Ek destek fonksiyonları olan `fake_password_hasher` ve `fake_save_user` sadece verinin olası bir akışını göstermek içindir; elbette gerçek bir güvenlik sağlamazlar.
