We will create a `PeeweeConnectionState`:

```Python hl_lines="10-19"
{!../../../docs_src/sql_databases_peewee/sql_app/database.py!}
```

This class inherits from a special internal class used by Peewee.

It has all the logic to make Peewee use `contextvars` instead of `threading.local`.

### `Response`

The main `Response` class, all the other responses inherit from it.

You can return it directly.

It accepts the following parameters:

* `content` - A `str` or `bytes`.
* `status_code` - An `int` HTTP status code.
* `headers` - A `dict` of strings.

We could do better.

We can declare a `UserBase` model that serves as a base for our other models. And then we can make subclasses of that model that inherit its attributes (type declarations, validation, etc).

All the data conversion, validation, documentation, etc. will still work as normally.

$ python ./scripts/docs.py new-lang ht

Successfully initialized: docs/ht
```

</div>

现在，你可以在编辑器中查看新创建的目录 `docs/ht/`。

这条命令会生成一个从 `en` 版本继承了所有属性的配置文件 `docs/ht/mkdocs.yml`:

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

!!! tip
    你也可以自己手动创建包含这些内容的文件。

这条命令还会生成一个文档主页 `docs/ht/index.md`，你可以从这个文件开始翻译。

然后，你可以根据上面的"已有语言"的指引继续进行翻译。

    !!! tip
        Prefer to use the `Annotated` version if possible.

    ```Python hl_lines="7"
    {!> ../../../docs_src/request_files/tutorial001.py!}
    ```

!!! info
    `File` is a class that inherits directly from `Form`.

    But remember that when you import `Query`, `Path`, `File` and others from `fastapi`, those are actually functions that return special classes.

!!! tip

* Data conversion
* Data validation
* Automatic documentation

## Special types and validation

Apart from normal singular types like `str`, `int`, `float`, etc. you can use more complex singular types that inherit from `str`.

Obiges Kommando hat eine Datei `docs/ht/mkdocs.yml` mit einer Minimal-Konfiguration erstellt, die alles von der `en`-Version erbt:

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

!!! tip "Tipp"
    Sie können diese Datei mit diesem Inhalt auch einfach manuell erstellen.
