Pass binary to `cast_attachments` about arc_ecto HOT 5 OPEN

arc works fine if you pass a map %{binary: <<your bytes>>, filename: "filename.txt"}. The problem in arc_ecto is cast_attachment matches the file arg against %{__struct__: Plug Upload}.

So as a workaround, you can pass:

    %{
      __struct__: Plug.Upload,
      binary: bytes,
      filename: "filename.txt"
    }

In place of an actual Plug.Upload. Ugly as sin but it works.

I agree, this would be a nice feature to have. I can try to make a PR if you'd like, @stavro.

@darkbaby123 @philipgiuliani A workaround you can use for now is to write the data out to a temp file and pass that temp file's path in.

Hi, im using v0.7.0 and still could not pass binary data to cast_attachments. Was this ever solved? Also I tried using Plug.Upload by creating a temp file but it seems it works at times and does not work the other times. Can someone help me out here. My function that converts my base64 to Plug.Upload is as follow
def process_image(image_base64) do {:ok, image_binary} = Base.decode64(image_base64) filename = image_binary |> image_extension() |> unique_filename() case File.write!("candidate_pics/#{filename}", image_binary, [:binary]) do :ok -> %Plug.Upload{ content_type: "image/#{image_extension(image_binary)}", filename: filename, path: Path.expand("candidate_pics/#{filename}") |> Path.absname() } {:error, reason} -> {:error, reason} end end

Going to bump this issue and the accompanying PR #87 that fixes this.

For now, I'm just going to work off that branch until this is merged.

Nice work with the project @stavro, I know you must be busy.

I am doing the same in my project. Version v0.5 broke this behaviour and I am not aware of a workaround. If you use version v0.5.0-rc1 or v0.4.0 everything should be fine.

@stavro Is there a way to do this now?
