And then you can return any object you need, as you normally would (a `dict`, a database model, etc).

And if you declared a `response_model`, it will still be used to filter and convert the object you returned.

## Преобразование любых данных к формату, совместимому с JSON { #convert-any-data-to-json-compatible }

Чтобы преобразовать любые данные к формату, совместимому с JSON, прочитайте документацию: [Руководство — JSON-совместимый кодировщик](../tutorial/encoder.md){.internal-link target=_blank}.

            "msg": "Extra inputs are not permitted",
            "input": "plumbus",
        }
    ]
}
```

## Как отключить автоматическое преобразование подчеркиваний { #disable-convert-underscores }

Как и в случае с обычными заголовками, если у вас в именах параметров имеются символы подчеркивания, они **автоматически преобразовываются в дефис**.

    /**
     * Default constructor.
     */
    public FessApiAction() {
        super();
    }

    /**
     * Message manager for handling internationalized messages and validation errors.
     * Used to convert validation messages to localized text for API responses.
     */
    @Resource
    protected MessageManager messageManager;

    /**
     * Service for managing API access tokens including validation and authentication.

        long nanos = duration.toNanos();
        if (nanos > 0) {
            double seconds = nanos / (double) TimeUnit.SECONDS.toNanos(1); // Convert to fractional seconds
            double bytesPerSecond = contentLength / seconds;
            message.append(" at ");
            format.formatRate(message, bytesPerSecond);
        }

     * @return the timeout in milliseconds
     */
    public long getTimeoutMs() {
        if (timeout100Ns == 0) {
            return 0; // Persistent handles
        }
        // Convert from 100-nanosecond intervals to milliseconds
        // 1 ms = 10,000 * 100ns intervals
        return timeout100Ns / 10000L;
    }

    /**
     * Get the flags
     * @return the flags
     */

      sizeRemaining -= count;
      hashMultiset.add(value, count);
      linkedHashMultiset.add(value, count);
      treeMultiset.add(value, count);
    }

    // TODO(kevinb): convert to assert once benchmark tests enable asserts by default
    Preconditions.checkState(hashMultiset.size() == size);
  }

  @Benchmark
  int hashMultiset(int reps) {
    int sum = 0;

            System.arraycopy(outputBuffer, offset + 12, fileNameBytes, 0, fileNameLength);
            String fileName = new String(fileNameBytes, StandardCharsets.UTF_16LE);

            // Convert action to our enum
            DirectoryChangeType changeType = convertAction(action);

            // Reset failure count on successful notification
            resetFailureCount(handle);

Because the editor knows the types of the variables, you don't only get completion, you also get error checks:

Now you know that you have to fix it, convert `age` to a string with `str(age)`:

{* ../../docs_src/python_types/tutorial004_py39.py hl[2] *}

## Declaring types { #declaring-types }

You just saw the main place to declare type hints. As function parameters.

            "loc": ["header", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus",
        }
    ]
}
```

## Desativar conversão de underscores { #disable-convert-underscores }

Da mesma forma que com parâmetros de cabeçalho normais, quando você tem caracteres de sublinhado nos nomes dos parâmetros, eles são **automaticamente convertidos em hifens**.
