## Instalar o `SQLModel` { #install-sqlmodel }

Primeiro, certifique-se de criar seu [ambiente virtual](../virtual-environments.md), ativá-lo e, em seguida, instalar o `sqlmodel`:

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>

To use forms, first install [`python-multipart`](https://github.com/Kludex/python-multipart).

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and then install it, for example:

```console
$ pip install python-multipart
```

///

## Import `Form` { #import-form }

Import `Form` from `fastapi`:

{* ../../docs_src/request_forms/tutorial001_an_py310.py hl[3] *}

/// info | 情報

アップロードされたファイルやフォームデータを受信するには、まず[`python-multipart`](https://github.com/Kludex/python-multipart)をインストールします。

[仮想環境](../virtual-environments.md)を作成し、それを有効化してから、例えば次のようにインストールしてください:

```console
$ pip install python-multipart
```

///

## `File`と`Form`のインポート { #import-file-and-form }

{* ../../docs_src/request_forms_and_files/tutorial001_an_py310.py hl[3] *}

本例的子应用挂载在 `/subapi` 路径下：

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[11, 19] *}

### 查看自动 API 文档 { #check-the-automatic-api-docs }

现在，运行 `fastapi` 命令：

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

然后在 [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs) 打开文档。

你可以使用 **Pydantic 模型** 在 FastAPI 中宣告 **表單欄位**。

/// info | 說明

要使用表單，首先安裝 [`python-multipart`](https://github.com/Kludex/python-multipart)。

請先建立[虛擬環境](../virtual-environments.md)、啟用後再安裝，例如：

```console
$ pip install python-multipart
```

///

/// note | 注意

此功能自 FastAPI 版本 `0.113.0` 起支援。🤓

///

## 針對表單的 Pydantic 模型 { #pydantic-models-for-forms }

Bir [virtual environment](../virtual-environments.md) oluşturduğunuzdan, onu etkinleştirdiğinizden emin olun ve ardından örneğin şöyle kurun:

```console
$ pip install python-multipart
