高度なシナリオでは、「キャッシュされた」値を使うのではなく、同じリクエストの各ステップ（おそらく複数回）で依存関係を呼び出す必要があることがわかっている場合、`Depens`を使用する際に、`use_cache=False`というパラメータを設定することができます。

```Python hl_lines="1"
async def needy_dependency(fresh_value: str = Depends(get_value, use_cache=False)):
    return {"fresh_value": fresh_value}
```

## まとめ

ここで使われている派手な言葉は別にして、**依存性注入** システムは非常にシンプルです。

    background_tasks_param_name: Optional[str] = None
    security_scopes_param_name: Optional[str] = None
    own_oauth_scopes: Optional[list[str]] = None
    parent_oauth_scopes: Optional[list[str]] = None
    use_cache: bool = True
    path: Optional[str] = None
    scope: Union[Literal["function", "request"], None] = None

    @cached_property
    def oauth_scopes(self) -> list[str]:

            json_schema_extra=json_schema_extra,
            **extra,
        )

class Depends:
    dependency: Optional[Callable[..., Any]] = None
    use_cache: bool = True
    scope: Union[Literal["function", "request"], None] = None

    * The cache can be disabled per dependency declaration, using `use_cache=False` as in `Depends(your_dependency, use_cache=False)`.
