**remember** to pass the arguments to the function for it to work correctly, otherwise the values will be different from what you expect (e.g. `QueryInfo` or something similar instead of `str`). And your editor won't complain, and Python won't complain running that function, only when the operations inside error out.

Because `Annotated` can have more than one metadata annotation, you could now even use the same function with other tools, like <a href="https://typer.tiangolo.com/" class="external-link"...

### Запустіть

Запустіть server з:

<div class="termy">

```console
$ uvicorn main:app --reload

INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
INFO:     Started reloader process [28720]
INFO:     Started server process [28722]
INFO:     Waiting for application startup.

## Dynamic systems without restarting server

The following sub-systems are dynamic i.e., configuration parameters for each sub-systems can be changed while the server is running without any restarts.

```

            GWT issues some scary warnings while running tests, but I believe they are harmless.
            Let's take the warnings for one module, c.g.c.base.testModule, as an example:

              [INFO] Validating units:

errors.invalid_str_is_included = {1} is invalid for {0}.
errors.blank_password = Password is required.
errors.invalid_confirm_password = Does not match a confirmation password.
errors.cannot_delete_doc_because_of_running = A crawler is running. You cannot delete documents.
errors.failed_to_delete_doc_in_admin = Failed to delete a document.
errors.failed_to_send_testmail=Failed to send a test mail.

errors.invalid_str_is_included = {1} is invalid for {0}.
errors.blank_password = Password is required.
errors.invalid_confirm_password = Does not match a confirmation password.
errors.cannot_delete_doc_because_of_running = A crawler is running. You cannot delete documents.

### 애플리케이션 실행하기

애플리케이션을 실행하려면 다음 명령을 사용합니다:

<div class="termy">

```console
$ fastapi dev main.py

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

</div>

그런 다음 `/docs` UI로 이동하면, **FastAPI**가 해당 **model들**을 사용하여 API **문서를 생성**하는 것으르 확인할 수 있습니다. 또한 이 모델들은 데이터를 직렬화하고 검증하는 데에도 사용됩니다.

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

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

</div>
