### Leer Heroes { #read-heroes }

Podemos **leer** `Hero`s de la base de datos usando un `select()`. Podemos incluir un `limit` y `offset` para paginar los resultados.

### Leer Un Hero { #read-one-hero }

Podemos **leer** un único `Hero`.

#### `Hero` — *модель-таблица* { #hero-the-table-model }

Далее создадим `Hero`, фактическую *модель-таблицу*, с **дополнительными полями**, которых может не быть в других моделях:

* `id`
* `secret_name`

Так как `Hero` наследуется от `HeroBase`, он **также** имеет **поля**, объявленные в `HeroBase`, поэтому все поля `Hero`:

* `id`
* `name`
* `age`
* `secret_name`

### Read One Hero { #read-one-hero }

We can **read** a single `Hero`.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[58:63] hl[60] *}

### Delete a Hero { #delete-a-hero }

We can also **delete** a `Hero`.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[66:73] hl[71] *}

### Run the App { #run-the-app }

You can run the app:

        )

        # Delete a hero
        response = client.delete(f"/heroes/{hero_id}")
        assert response.status_code == 200, response.text
        assert response.json() == snapshot({"ok": True})

        # The hero is no longer found
        response = client.get(f"/heroes/{hero_id}")
        assert response.status_code == 404, response.text

        # Delete a hero that does not exist

app = FastAPI()


@app.get("/items/{item_id}", response_model=Item, responses={404: {"model": Message}})
async def read_item(item_id: str):
    if item_id == "foo":
        return {"id": "foo", "value": "there goes my hero"}

#### `Hero` – das *Tabellenmodell* { #hero-the-table-model }

Dann erstellen wir `Hero`, das tatsächliche *Tabellenmodell*, mit den **zusätzlichen Feldern**, die nicht immer in den anderen Modellen enthalten sind:

* `id`
* `secret_name`

Da `Hero` von `HeroBase` erbt, hat es **auch** die **Felder**, die in `HeroBase` deklariert sind, also sind alle Felder von `Hero`:

* `id`
* `name`
* `age`

def test_path_operation(client: TestClient):
    response = client.get("/items/foo")
    assert response.status_code == 200, response.text
    assert response.json() == {"id": "foo", "value": "there goes my hero"}


def test_path_operation_img(client: TestClient):
    shutil.copy("./docs/en/docs/img/favicon.png", "./image.png")
    response = client.get("/items/foo?img=1")
    assert response.status_code == 200, response.text

)
async def read_item(item_id: str, img: bool | None = None):
    if img:
        return FileResponse("image.png", media_type="image/png")
    else:
