### Create a Hero { #create-a-hero }

Because each SQLModel model is also a Pydantic model, you can use it in the same **type annotations** that you could use Pydantic models.

For example, if you declare a parameter of type `Hero`, it will be read from the **JSON body**.

The same way, you can declare it as the function's **return type**, and then the shape of the data will show up in the automatic API docs UI.

Da jedes SQLModel-Modell auch ein Pydantic-Modell ist, können Sie es in denselben **Typannotationen** verwenden, die Sie für Pydantic-Modelle verwenden könnten.

Wenn Sie beispielsweise einen Parameter vom Typ `Hero` deklarieren, wird er aus dem **JSON-Body** gelesen.

Auf die gleiche Weise können Sie es als **Rückgabetyp** der Funktion deklarieren, und dann wird die Form der Daten in der automatischen API-Dokumentation angezeigt.

`APIRouter`는 "미니 `FastAPI`" 클래스라고 생각할 수 있습니다.

동일한 옵션들이 모두 지원됩니다.

동일한 `parameters`, `responses`, `dependencies`, `tags` 등등.
