New method AttachmentsList.add(attachment)

[TomFreudenberg]

I added a new function to the AttachmentsList class to manipulate attachments without decode/encode and rewriting id's etc.

We are using the Mail gem for a message router and need everytime to copy the original attachments.

Instead of re-creating that attachments like

mail_in = Mail.read_from_string(mail_source)
mail_out = Mail.new
# copy attachments
mail_in.attachments.each do |a| 
  mail_out.attachments[a.filename] = { 
    :mime_type => a.mime_type, 
    :encoding => a.content_transfer_encoding,
    :content_id => a.content_id,
    :content_disposition => a.content_disposition,
    :content => a.decoded
  } 
end

now you just can append the already processed attachment from original message.

mail_in = Mail.read_from_string(mail_source)
mail_out = Mail.new
# copy attachments
mail_in.attachments.each { |a| mail_out.attachments.add(a) }

Hopefully this change makes sense for you.

Looking for your feedback

Can these be added using the existing parts API?

Hi @jeremy

what does that mean: "Can these be added using the existing parts API?"

Should I check it with latest sources?

Thanks for some more info

Give this a shot:

mail_in = Mail.new(mail_source)
mail_out = Mail.new
mail_in.attachments.each { |part| mail_out.body << part }
