# General - How To - Recipes

Here are several pointers to other places in the docs, for general or frequent questions.

## Filter Data - Security

To ensure that you don't return more data than you should, read the docs for [Tutorial - Response Model - Return Type](../tutorial/response-model.md){.internal-link target=_blank}.

## Documentation Tags - OpenAPI

    assert response.json() == {"name": "Bar", "description": "The Bar fighters"}


def test_read_item_public_data():
    response = client.get("/items/bar/public")
    assert response.status_code == 200, response.text
    assert response.json() == {
        "name": "Bar",
        "description": "The Bar fighters",
        "price": 62,
    }

* ✨ Add support for declaring `UploadFile` parameters without explicit `File()`. PR [#4469](https://github.com/tiangolo/fastapi/pull/4469) by [@tiangolo](https://github.com/tiangolo). New docs: [Request Files - File Parameters with UploadFile](https://fastapi.tiangolo.com/tutorial/request-files/#file-parameters-with-uploadfile).

        return {"name": name, "description": "model-a-desc", "foo": model_c}

    client = TestClient(app)
    return client

def test_filter_sub_model(client: TestClient):
    response = client.get("/model/modelA")
    assert response.status_code == 200, response.text
    assert response.json() == {
        "name": "modelA",
        "description": "model-a-desc",

# Request Files

You can define files to be uploaded by the client using `File`.

!!! info
    To receive uploaded files, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

    E.g. `pip install python-multipart`.

    This is because uploaded files are sent as "form data".

## Import `File`

Import `File` and `UploadFile` from `fastapi`:

=== "Python 3.9+"

# 静的ファイル

`StaticFiles` を使用して、ディレクトリから静的ファイルを自動的に提供できます。

## `StaticFiles` の使用

* `StaticFiles` をインポート。
* `StaticFiles()` インスタンスを生成し、特定のパスに「マウント」。

```Python hl_lines="2  6"
{!../../../docs_src/static_files/tutorial001.py!}
```

!!! note "技術詳細"
    `from starlette.staticfiles import StaticFiles` も使用できます。

    **FastAPI**は、開発者の利便性のために、`starlette.staticfiles` と同じ `fastapi.staticfiles` を提供します。しかし、実際にはStarletteから直接渡されています。

## Use `StaticFiles`

* Importe `StaticFiles`.
* "Monte" uma instância de `StaticFiles()` em um caminho específico.

```Python hl_lines="2  6"
{!../../../docs_src/static_files/tutorial001.py!}
```

!!! note "Detalhes técnicos"
    Você também pode usar `from starlette.staticfiles import StaticFiles`.

    items["foo"] = {"name": "Fighters"}
    items["bar"] = {"name": "Tenders"}


@app.get("/items/{item_id}")
async def read_items(item_id: str):
    return items[item_id]


def test_read_items():
    with TestClient(app) as client:
        response = client.get("/items/foo")
        assert response.status_code == 200

## `File` und `Form` importieren

=== "Python 3.9+"

    ```Python hl_lines="3"
    {!> ../../../docs_src/request_forms_and_files/tutorial001_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="1"
    {!> ../../../docs_src/request_forms_and_files/tutorial001_an.py!}
    ```

=== "Python 3.8+ nicht annotiert"

    !!! tip "Tipp"
        Bevorzugen Sie die `Annotated`-Version, falls möglich.
