!!! tip
    请注意，读取用户（从 API 返回）时将使用不包括`password`的`User` Pydantic*模型*。

### 使用 Pydantic 的`orm_mode`

现在，在用于查询的 Pydantic*模型*`Item`中`User`，添加一个内部`Config`类。

此类[`Config`](https://docs.pydantic.dev/latest/api/config/)用于为 Pydantic 提供配置。

在`Config`类中，设置属性`orm_mode = True`。

    {!> ../../../docs_src/sql_databases/sql_app_py310/schemas.py!}

from functools import lru_cache

                    "name": "Foo",

app = FastAPI()


class Item(BaseModel):
    name: str
    description: Union[str, None] = None
    price: float
    tax: Union[float, None] = None

    class Config:
        schema_extra = {
            "examples": [
                {
                    "name": "Foo",

```

</div>

Now you can check in your code editor the newly created directory `docs/ht/`.

That command created a file `docs/ht/mkdocs.yml` with a simple config that inherits everything from the `en` version:

```yaml
INHERIT: ../en/mkdocs.yml
```

!!! tip
    You could also simply create that file with those contents manually.

    github_sponsors_path.write_text(new_github_sponsors_content, encoding="utf-8")
    logging.info("Setting up GitHub Actions git user")
    subprocess.run(["git", "config", "user.name", "github-actions"], check=True)
    subprocess.run(
        ["git", "config", "user.email", "******@****.***"], check=True
    )
    branch_name = "fastapi-people"
    logging.info(f"Creating a new branch {branch_name}")

JSON Schemaの追加情報を宣言する方法はいくつかあります。

## Pydanticの`schema_extra`

<a href="https://docs.pydantic.dev/latest/concepts/json_schema/#schema-customization" class="external-link" target="_blank">Pydanticのドキュメント: スキーマのカスタマイズ</a>で説明されているように、`Config`と`schema_extra`を使ってPydanticモデルの例を宣言することができます:

```Python hl_lines="15 16 17 18 19 20 21 22 23"
{!../../../docs_src/schema_extra_example/tutorial001.py!}
```

その追加情報はそのまま出力され、JSON Schemaに追加されます。

## `Field`の追加引数

### ⚙️ Pydantic `orm_mode`

🔜, Pydantic *🏷* 👂, `Item` & `User`, 🚮 🔗 `Config` 🎓.

👉 <a href="https://docs.pydantic.dev/latest/api/config/" class="external-link" target="_blank">`Config`</a> 🎓 ⚙️ 🚚 📳 Pydantic.

`Config` 🎓, ⚒ 🔢 `orm_mode = True`.
