 * Helper class for indexing operations in the Fess search engine.
 * This class provides functionality for sending documents to the search engine,

 * thumbnail processing during indexing.
 *
 * <p>The IndexingHelper manages bulk operations, handles retries on failures,
 * and provides various query-based operations for document management.

- The `kubectl debug` is able to create ephemeral containers in pre-1.22 clusters with the `EphemeralContainers` feature enabled. Note that versions of kubectl prior to 1.22 are unable to create ephemeral containers in clusters version 1.22 and greater due to an API change.

## Pydanticの `BaseModel` をインポート { #import-pydantics-basemodel }

まず、`pydantic` から `BaseModel` をインポートする必要があります:

{* ../../docs_src/body/tutorial001_py310.py hl[2] *}

## データモデルの作成 { #create-your-data-model }

次に、`BaseModel` を継承するクラスとしてデータモデルを宣言します。

すべての属性に標準のPython型を使用します:

{* ../../docs_src/body/tutorial001_py310.py hl[5:9] *}

当你用以下方式安装 `all` 扩展时，它也会被一并安装：

<div class="termy">

```console
$ pip install "fastapi[all]"
---> 100%
```

### 创建 `Settings` 对象 { #create-the-settings-object }

从 Pydantic 导入 `BaseSettings` 并创建一个子类，这与创建 Pydantic 模型非常相似。

与 Pydantic 模型一样，用类型注解声明类属性，也可以指定默认值。

你可以使用与 Pydantic 模型相同的验证功能和工具，例如不同的数据类型，以及使用 `Field()` 进行附加验证。
