枚举类 `ModelName` 中的*枚举元素*支持比较操作：

{* ../../docs_src/path_params/tutorial005.py hl[17] *}

#### 获取*枚举值*

使用 `model_name.value` 或 `your_enum_member.value` 获取实际的值（本例中为**字符串**）：

{* ../../docs_src/path_params/tutorial005.py hl[20] *}

/// tip | 提示

使用 `ModelName.lenet.value` 也能获取值 `"lenet"`。

///

#### 返回*枚举元素*

即使嵌套在 JSON 请求体里（例如， `dict`），也可以从*路径操作*返回*枚举元素*。

Então você pode escrever um template em `templates/item.html`, por exemplo:

```jinja hl_lines="7"
{!../../docs_src/templates/templates/item.html!}
```

### Valores de contexto do template { #template-context-values }

No código HTML que contém:

{% raw %}

```jinja
Item ID: {{ id }}
```

{% endraw %}

...aparecerá o `id` obtido do "context" `dict` que você passou:

```Python
{"id": id}
```
