Creating a Message with Attachement GmailV1 API ruby

Question

I am trying to send a en email with an attachment via the GmailV1 API. However it just isn't working due to Missing Draft Message errors.

According to RubyDoc I tried to create a draft message as follows:

The GmailV1:GmailService.create_user_draft() methods takes in an identifier and a draft_object (accepting 'me' for the authorized user). A draft object (Google::Apis::GmailV1::Draft) takes a message in the form of Google::Apis::GmailV1::Message which in turn takes a payload in the form of Google::Apis::GmailV1::MessagePart which has the desired filename method.

So I ran this code:

##assume client is an authorized instance of Google::Apis::GmailV1:GmailService
msg_part = Google::Apis::GmailV1::MessagePart.new(filename: 'path/to/file')
msg = Google::Apis::GmailV1::Message.new(payload: msg_part)
draft = Google::Apis::GmailV1::Draft.new(message: msg)
client.create_user_draft('me', draft)

>> Google::Apis::ClientError: invalidArgument: Missing draft message

How Come?

Versions:

google-api-client 0.9.9
googleauth 0.5.1
ruby 2.3.1p112

Have you stumbled upon this great answer? Might give some clues. — Tholle

I have but it refers to an old version of the API that is completely different now in every way, from authentication to making API requests. It doesn't apply / help here. — Killerpixler

Using the GmailService class as described here I was able to save a draft using the code below. I think the key is that the raw keyword is required in the message.

result = service.create_user_draft(
  user_id,
  Google::Apis::GmailV1::Draft.new(
    :message => Google::Apis::GmailV1::Message.new(
      :raw => "To: [email protected]\r\nSubject: Test Message\r\n\r\nTest Body"
    )
  )
)

I solved this problem creating first a Mail object with the 'mail' gem in this way:

require 'mail'

mail = Mail.new
mail['from'] = '[email protected]'
mail[:to]    = '[email protected]'
mail.subject = 'This is a test email'
mail.body 'this is the body'
mail.add_file("./path/to/file")
#... and other ...

then i converted this in a raw object:

raw_message = mail.to_s

then i create gmail message with this raw:

message = Google::Apis::GmailV1::Message.new(
  :raw => raw_message  
)

and finnaly:

draft = Google::Apis::GmailV1::Draft.new(message: message)
gmail.create_user_draft('me', draft)
