How to add multiple files to one field?

[aMytho]

I have a project where users can upload html/css/js files to be displayed to other users. I'm having trouble getting it to allow multiple files for one field. I can get around it by zipping the file but then I have to unzip it whenever it is served to a user which isn't ideal.

I'm assuming I have to do something like
field :interactive_project {:array, Glimesh.Interactive.Type}
Then in migrations
add :interactive_project, {:array, :string}

This does compile but I don't know how to cast the attachment. It seems to only allow 1 file for that.

# Other validations...
changeset |> cast_attachments(attrs, [:poster, :chat_bg, :interactive_project])

Looks like PR #41 would add the functionality I need.
