How to cancel all pending uploads at once

Hello! I wanted to ask if there was a better way to cancel all pending uploads in a live upload form. I know there is cancel_upload but not sure if the best way would be something like reduce over all the uploads and use their refs with this function?

Any suggestions would be appreciated.

Here’s how I do it. Allowed upload is named :images.

def handle_event("cancel-uploads", _params, socket) do
  entries = socket.assigns.uploads.images.entries

  {:noreply, Enum.reduce(entries, socket, &cancel_upload(&2, :images, &1.ref))}
end

Thank you! I ended up using this which is similar:

def handle_event("clear", _params, socket) do
  entries = socket.assigns.uploads.images.entries

  updated_socket = 
    Enum.reduce(entries, socket, fn entry, acc ->
      cancel_upload(acc, :images, entry.ref)
    end)

  {:noreply, updated_socket}
end

Ha, yep, exactly the same thing just using fn instead of the capture syntax. I should probably not use the capture syntax as I usually don’t if there are more than one argument.
