그런 다음 환경 변수 `OPENAPI_URL`을 빈 문자열로 설정하여 OpenAPI(UI docs 포함)를 비활성화할 수도 있습니다. 예를 들어:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

그리고 `/openapi.json`, `/docs` 또는 `/redoc`의 URL로 이동하면 `404 Not Found`라는 오류가 다음과 같이 표시됩니다:

```JSON
{
    "detail": "Not Found"
}

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[25:30]  hl[25:27,30] *}

### Создание таблиц базы данных при старте { #create-database-tables-on-startup }

Мы создадим таблицы базы данных при запуске приложения.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[32:37] hl[35:37] *}

Здесь мы создаём таблицы в обработчике события запуска приложения.

Тепер запустіть команду `fastapi`:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

І відкрийте документацію за адресою [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

Benzer şekilde, bir path operation'ı yeniden tanımlayamazsınız:

{* ../../docs_src/path_params/tutorial003b_py310.py hl[6,11] *}

Path önce eşleştiği için her zaman ilk olan kullanılır.
