## Reduce duplication { #reduce-duplication }

Reducing code duplication is one of the core ideas in **FastAPI**.

As code duplication increments the chances of bugs, security issues, code desynchronization issues (when you update in one place but not in the others), etc.

And these models are all sharing a lot of the data and duplicating attribute names and types.

### Вимкніть автоматичну документацію { #disable-the-automatic-docs }

Перший крок - вимкнути автоматичну документацію, адже типово вона використовує стандартний CDN.

Щоб їх вимкнути, встановіть їхні URL у `None` під час створення вашого застосунку `FastAPI`:

{* ../../docs_src/custom_docs_ui/tutorial001_py310.py hl[8] *}

### Додайте користувацьку документацію { #include-the-custom-docs }

`id` der **Primärschlüssel** in der SQL-Datenbank ist (Sie können mehr über SQL-Primärschlüssel in der SQLModel-Dokumentation erfahren).

    **Hinweis:** Wir verwenden für das Primärschlüsselfeld `int | None`, damit wir im Python-Code *ein Objekt ohne `id` erstellen* können (`id=None`), in der Annahme, dass die Datenbank sie *beim Speichern generiert*. SQLModel versteht, dass die Datenbank die `id` bereitstellt, und *definiert die Spalte im Datenbankschema als ein Nicht-Null-`INTEGER`*. Siehe...

    for prod and one for tests. However, unlike our other packages, as of this
    writing it has test supersource but no prod supersource.

    GWT happens to use the prod .gwt.xml, so it looks for no supersource for
    tests, either. This causes it to fail to find AtomicLongMapTest.

    Our workaround is to tell GWT that util.concurrent and all other packages

Ayrıca bir uygulamayı deploy ederken ihtiyaç duyacağınız pek çok şeyi de sizin için halleder; örneğin:

* HTTPS
* Replication (çoğaltma), request'lere göre autoscaling ile

# Full Stack FastAPI Şablonu { #full-stack-fastapi-template }

Şablonlar genellikle belirli bir kurulumla gelir, ancak esnek ve özelleştirilebilir olacak şekilde tasarlanırlar. Bu sayede şablonu projenizin gereksinimlerine göre değiştirip uyarlayabilir, çok iyi bir başlangıç noktası olarak kullanabilirsiniz. 🏁

Bu şablonu başlangıç için kullanabilirsiniz; çünkü ilk kurulumun, güvenliğin, veritabanının ve bazı API endpoint'lerinin önemli bir kısmı sizin için zaten hazırlanmıştır.
