### Describe the problem

Hi Baserow community !

I have successfuly uploaded a file to a row using the python API. However I couldn’t figure out how to add up files in a single row. Everytime I patch the row, the previous file is being replaced with the new one.

I’m using this function

```auto
def basrw_update_row(
        collaborateur: str = "", 
        row_id: str = "", 
        data = ""):
    token = "QRu6Gu7g7S4gD..."
    url = f"http://vision.axe.lan:3001/api/database/rows/table/371/{row_id}/?user_field_names=true"
    response = requests.patch(
        url = url,
        headers={
            "Authorization": f"Token {token}",
            "Content-Type": "application/json"
        },
        json={
        "Collaborateur": f"{collaborateur}",
        "Fichiers": [data,]
        }
    )
    return response.text

```

#### How many rows in total do you have in your Baserow tables?

3 😄

Hi,

If you patch a record, you overwrite the values of all fields mentioned in the body of the request.

To add a file, you first need to perform a `request.get()` operation. This returns a list of files that are already added to the record. Add the new file to the list pass this updated list in the patch request.
