This is the preferred method for any new dashboards.

## Legacy Dashboards

Many of our older dashboards are manually created in the UI and exported as JSON and checked in.

## Generation

举个例子，当你在 NoSQL 数据库中保存了具有许多可选属性的模型，但你又不想发送充满默认值的很长的 JSON 响应。

### 使用 `response_model_exclude_unset` 参数

你可以设置*路径操作装饰器*的 `response_model_exclude_unset=True` 参数：

```Python hl_lines="24"
{!../../docs_src/response_model/tutorial004.py!}
```

然后响应中将不会包含那些默认值，而是仅有实际设置的值。

因此，如果你向*路径操作*发送 ID 为 `foo` 的商品的请求，则响应（不包括默认值）将为：

```JSON
{
    "name": "Foo",
    "price": 50.2
}
```

settings = Settings()
if settings.debug:
    logging.basicConfig(level=logging.DEBUG)
else:
    logging.basicConfig(level=logging.INFO)
logging.debug(f"Using config: {settings.json()}")
g = Github(settings.token.get_secret_value())
repo = g.get_repo(settings.github_repository)
for pr in repo.get_pulls(state="open"):
    logging.info(f"Checking PR: #{pr.number}")
    pr_labels = list(pr.get_labels())

/// note | "Starlette 技术细节"

**FastAPI** 的 `UploadFile` 直接继承自 **Starlette** 的 `UploadFile`，但添加了一些必要功能，使之与 **Pydantic** 及 FastAPI 的其它部件兼容。

## 什么是 「表单数据」

与 JSON 不同，HTML 表单（`<form></form>`）向服务器发送数据通常使用「特殊」的编码。

**FastAPI** 要确保从正确的位置读取数据，而不是读取 JSON。

/// note | "技术细节"

不包含文件时，表单数据一般用 `application/x-www-form-urlencoded`「媒体类型」编码。

但表单包含文件时，编码为 `multipart/form-data`。使用了 `File`，**FastAPI** 就知道要从请求体的正确位置获取文件。

	if context, ok := h[xhttp.AmzServerSideEncryptionKmsContext]; ok {
		b, err := base64.StdEncoding.DecodeString(context[0])
		if err != nil {
			return "", nil, err
		}

		json := jsoniter.ConfigCompatibleWithStandardLibrary
		if err := json.Unmarshal(b, &ctx); err != nil {
			return "", nil, err
		}
	}

	keyID := h.Get(xhttp.AmzServerSideEncryptionKmsID)

Ele também não controla modelos aninhados muito bem. Então, se o corpo JSON na requisição for um objeto JSON que contém campos internos que contém objetos JSON aninhados, ele não consegue ser validado e documentado apropriadamente.

Usar tipos Python para ter um ótimo suporte do editor.
