$ git clone git://github.com/mikel/rails.git $ cd rails/actionmailer $ gem install mail $ rake You should get 0 errors and 0 failures. This is tested on Ruby 1.8.6, 1.8.7, 1.9.1 and 1.9.1-head (1.9.2) Please feel free to test with your favourite ActionMailer rails app. The major changes from using TMail to Mail are: 1) mail_object#to_s returns the encoded value ready for insert into email, so this includes the header field name. If you want the decoded part of a header field, call #decoded 2) Mail does not have "quoted_body", "quoted_subject" etc. All of these are accessed via body.encoded, subject.encoded etc 3) Every part of a Mail object returns an object, never a string. So Mail.body returns a Mail::Body class object, need to call #encoded or #decoded to get the string you want 4) Mail::Message#set_content_type does not exist, it is simply Mail::Message#content_type 5) Every mail message gets a unique message_id unless you specify one, had to change all the tests that check for equality with expected.encoded == actual.encoded to first replace their message_ids with control values 6) Mail now has a proper concept of parts, remove the ActionMailer::Part and ActionMailer::PartContainer classes 7) Calling #encoded on any object returns it as a string ready to go into the output stream of an email, this means it includes the \r\n at the end of the lines and the object is pre-wrapped with \r\n\t if it is a header field. Also, the "encoded" value includes the field name if it is a header field. 8) Attachments are only the actual attachment, with filename etc. A part contains an attachment. The part has the content_type etc. So attachments.last.content_type is invalid. But parts.last.content_type 9) There is no idea of a "sub_head" in Mail. A part is just a Message with some extra functionality, so it just has a "header" like a normal mail message Mikel -- http://lindsaar.net/ Rails, RSpec and Life blog.... -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
