# `UploadFile` class

You can define *path operation function* parameters to be of the type `UploadFile` to receive files from the request.

You can import it directly from `fastapi`:

```python
from fastapi import UploadFile
```

::: fastapi.UploadFile
    options:
        members:
            - file
            - filename
            - size
            - headers
            - content_type
            - read

            "-PmaxParallelForks=%maxParallelForks%",
            pluginPortalUrlOverride,
            "-s",
            "--no-configuration-cache",
            "%additional.gradle.parameters%",
            "--daemon",
            "--continue",
            "-DbuildScan.PartOf=PullRequestFeedback,ReadyforNightly,ReadyforRelease",
            "-Dscan.tag.PerformanceTest"
        )

Ou a dependência não retorna nenhum valor.

Mas você ainda precisa que ela seja executada/resolvida.

Para esses casos, em vez de declarar um parâmetro em uma *função de operação de rota* com `Depends`, você pode adicionar um argumento `dependencies` do tipo `list` ao decorador da operação de rota.

## Adicionando `dependencies` ao decorador da operação de rota

- At the popup window, click `Import Settings from VCS`. Wait a few seconds. 
  - If the error says "Context Parameter 'Branch' missing", it's ok. Click into the error and add a context parameter `Branch` with value `myTestBranch`. Go back and it automatically reloads.
  - If there are any errors, read the error and fix your code.
