E pronto.

**2 linhas**.

E com a mesma forma e estrutura de todas as suas *funções de operação de rota*.

Você pode pensar nela como uma *função de operação de rota* sem o "decorador" (sem a linha `@app.get("/some-path")`).

E com qualquer retorno que você desejar.

Neste caso, a dependência espera por:

* Um parâmetro de consulta opcional `q` do tipo `str`.

/// tip | Подсказка

Обратите внимание, что также, как и в случае с зависимостями в декораторах *эндпоинтов* ([зависимости в декораторах операций пути](dependencies/dependencies-in-path-operation-decorators.md){.internal-link target=_blank}), никакого значения в *функцию эндпоинта* передано не будет.

///

В результате мы получим следующие эндпоинты:

* `/items/`
* `/items/{item_id}`

### German instructions about difficult to translate technical terms (written in first person, which is you)

compilation to JavaScript, it cannot rely on the types to define validation, serialization and documentation at the same time. Due to this and some design decisions, to get validation, serialization and automatic schema generation, it's needed to add decorators in many places. So, it becomes quite verbose.

It can't handle nested models very well. So, if the JSON body in the request is a JSON object that has inner fields that in turn are nested JSON objects, it cannot be properly documented and...

Das war's schon.

**Zwei Zeilen**.

Und sie hat die gleiche Form und Struktur wie alle Ihre *Pfadoperation-Funktionen*.

Sie können sie sich als *Pfadoperation-Funktion* ohne den „Dekorator“ (ohne `@app.get("/some-path")`) vorstellen.

Und sie kann alles zurückgeben, was Sie möchten.

In diesem Fall erwartet diese Abhängigkeit:

* Einen optionalen Query-Parameter `q`, der ein `str` ist.

    * Pydantic, JSON objen ne kadar derin (nested) olursa olsun doğrulamasını ve gösterimini yapıyor
* **Genişletilebilir**:
    * Pydantic özelleştirilmiş data tiplerinin tanımlanmasının yapılmasına izin veriyor ayrıca validator decoratorü ile senin doğrulamaları genişletip, kendi doğrulayıcılarını yazmana izin veriyor.
