    @Test

Предположим, у вас есть только один body-параметр `item` из Pydantic-модели `Item`.

По умолчанию, **FastAPI** ожидает получить тело запроса напрямую.

Но если вы хотите чтобы он ожидал JSON с ключом `item` с содержимым модели внутри, также как это происходит при объявлении дополнительных body-параметров, вы можете использовать специальный параметр `embed` у типа `Body`:

```Python
item: Item = Body(embed=True)
```

        raise HTTPException(status_code=404, detail="Item not found")
    return fake_db[item_id]


@app.post("/items/")
async def create_item(item: Item, x_token: str = Header()) -> Item:
    if x_token != fake_secret_token:
        raise HTTPException(status_code=400, detail="Invalid X-Token header")
    if item.id in fake_db:
        raise HTTPException(status_code=409, detail="Item already exists")
    fake_db[item.id] = item.model_dump()

    }

    /**
     * Checks whether this mapping item has pending updates.
     *
     * @return true if both newInputs and newOutput are not null, indicating pending updates
     */
    public boolean isUpdated() {
        return newInputs != null && newOutput != null;
    }
