/// tip

You could use any other SQL or NoSQL database library you want (in some cases called <abbr title="Object Relational Mapper: a fancy term for a library where some classes represent SQL tables and instances represent rows in those tables">"ORMs"</abbr>), FastAPI doesn't force you to use anything. 😎

///

As SQLModel is based on SQLAlchemy, you can easily use **any database supported** by SQLAlchemy (which makes them also supported by SQLModel), like:

But for security, as the server doesn't know it is behind a trusted proxy, it won't interpret those headers.

/// note | Technical Details

The proxy headers are:

* <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/X-Forwarded-For" class="external-link" target="_blank">X-Forwarded-For</a>

    * Например, `await myfile.seek(0)` перейдет к началу файла.
    * Это особенно удобно, если вы один раз выполнили команду `await myfile.read()`, а затем вам нужно прочитать содержимое файла еще раз.
* `close()`: Закрыть файл.

Поскольку все эти методы являются `async` методами, вам следует использовать "await" вместе с ними.

Например, внутри `async` *функции операции пути* можно получить содержимое с помощью:

```Python

        exceptionClass);
    checkArgument(
        hasConstructorUsableByGetChecked(exceptionClass),
        "Futures.getChecked exception type (%s) must be an accessible class with an accessible "
            + "constructor whose parameters (if any) must be of type String and/or Throwable",
        exceptionClass);
  }

  private FuturesGetChecked() {}

                    });
                }
            } else {
                oauth2.callback({auth: oauth2.auth, token: qp, isValid: isValid, redirectUrl: redirectUrl});
            }
            window.close();
        }

        if (document.readyState !== 'loading') {
            run();
        } else {
            document.addEventListener('DOMContentLoaded', function () {
                run();

		return "00000000000000000000000000000000"
	}
	b, err := os.Open(binPath)
	if err != nil {
		logger.Error("Calculating checksum failed: %s", err)
		return "00000000000000000000000000000000"
	}

	defer b.Close()
	io.Copy(mw, b)
	return hex.EncodeToString(mw.Sum(nil))
