## Editor-Unterstützung { #editor-support }

In Ihrem Editor erhalten Sie innerhalb Ihrer Funktion Typhinweise und Code-Vervollständigung überall (was nicht der Fall wäre, wenn Sie ein `dict` anstelle eines Pydantic-Modells erhalten hätten):

Se tivéssemos declarado `-> HeroPublic`, seu editor e o linter reclamariam (com razão) que você está retornando um `Hero` em vez de um `HeroPublic`.

Ao declará-lo no `response_model`, estamos dizendo ao **FastAPI** para fazer o seu trabalho, sem interferir nas anotações de tipo e na ajuda do seu editor e de outras ferramentas.

 * and reduces code duplication across strategy implementations.

 * <p>Strategies work with domtrip Documents for perfect formatting preservation.
 * Subclasses can create domtrip Editors from Documents as needed:
 * <pre>
 * Editor editor = new Editor(document);
 * // ... perform domtrip operations ...
 * // Document is automatically updated
 * </pre>

public abstract class AbstractUpgradeStrategy implements UpgradeStrategy {

By doing that, your editor can provide support even while processing items from the list:

Without types, that's almost impossible to achieve.

Notice that the variable `item` is one of the elements in the list `items`.

And still, the editor knows it is a `str`, and provides support for that.

You will rarely need to come back to the docs.

## Soporte de editor en todas partes { #editor-support-everywhere }

Y obtienes soporte de editor en todas partes.

Incluso para elementos dentro de listas:

No podrías obtener este tipo de soporte de editor si estuvieras trabajando directamente con `dict` en lugar de modelos Pydantic.

Algunos editores revisan los parámetros de función no usados y los muestran como errores.

Usando estas `dependencies` en el decorador de *path operation* puedes asegurarte de que se ejecutan mientras evitas errores en editores/herramientas.

También puede ayudar a evitar confusiones para nuevos desarrolladores que vean un parámetro no usado en tu código y puedan pensar que es innecesario.

Flask, Starlette, Responder ve benzerlerinde bu şekilde çalışıyor.

Fakat sonrasında yine mikro sözdizimi problemiyle karşılaşıyoruz. Python metinlerinin içinde koskoca bir YAML oluyor.

Editör bu konuda pek yardımcı olamaz. Üstelik eğer parametreleri ya da Marshmallow şemalarını değiştirip YAML kodunu güncellemeyi unutursak artık döküman geçerliliğini yitiriyor.

Some editors check for unused function parameters, and show them as errors.

Using these `dependencies` in the *path operation decorator* you can make sure they are executed while avoiding editor/tooling errors.
