# Additional Responses in OpenAPI { #additional-responses-in-openapi }

/// warning

This is a rather advanced topic.

If you are starting with **FastAPI**, you might not need this.

///

You can declare additional responses, with additional status codes, media types, descriptions, etc.

Those additional responses will be included in the OpenAPI schema, so they will also appear in the API docs.

    private SetView() {} // no subclasses but our own

    /**
     * Returns an immutable copy of the current contents of this set view. Does not support null
     * elements.
     *
     * <p><b>Warning:</b> this may have unexpected results if a backing set of this view uses a
     * nonstandard notion of equivalence, for example if it is a {@link TreeSet} using a comparator

        elements.charCount.text(count);

        var counter = elements.charCount.parent();
        counter.removeClass('warning danger');
        if (count >= maxLength * 0.95) {
            counter.addClass('danger');
        } else if (count >= maxLength * 0.8) {
            counter.addClass('warning');
        }

`jsonable_encoder`を用いて、入力データをJSONとして保存できるデータに変換することができます（例：NoSQLデータベース）。例えば、`datetime`を`str`に変換します。

`PUT`は、既存のデータを置き換えるべきデータを受け取るために使用されます。

### 置換についての注意 { #warning-about-replacing }

つまり、`PUT`を使用して以下のボディで項目`bar`を更新したい場合は:

```Python
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

            context.failure("Failed to discover POM files: " + e.getMessage());
            return 1;
        }

        if (pomMap.isEmpty()) {
            context.warning("No POM files found in " + startingDirectory);
            return 0;
        }

        context.info("Found " + pomMap.size() + " POM file(s)");

其他 ASGI 伺服器也有類似的指令，詳見各自的文件。

/// warning

Uvicorn 與其他伺服器支援 `--reload` 選項，對開發期間很有幫助。

`--reload` 會消耗更多資源，也較不穩定等。

它在開發階段很實用，但在生產環境中不應使用。
