Assigning directory path to downloaded email attachments

Rails
1

I am trying to build a script that will download emails + their
attachments (from gmail server) and place them both into their
respective folders (one folder containing one email + its attachments).

I have managed to build a script (by putting together pieces from two
separate scripts) that gets the job 90% done, my problem is that I can’t
get the attachments to save in the same folders as their respective
emails.

The folder structure where the emails are saved now is perfect, it is
just a question of getting the attachments to follow its respective
email into the folder.

If someone would have any tips for me I would be extremely grateful!

Here’s some sample code of the attached script:

def save_to_disk(email) ## downloads emails
dir = File.join(MAIL_FOLDER,email.subject)
FileUtils.mkdir_p(dir)

filename = File.join(dir,email.subject)
file = File.open(filename,“w”)
file.puts email.body
file.close

  if email.multipart? then    ## downloads attachments
     email.parts.each do |m|
       if m.disposition
         filename = m.disposition_param('filename')
         if filename[0,2]=='=?'
           filename.gsub!(/=\?[^\?]+\?(.)\?([^\?]+)\?=$/){$1=='B' ?

$2.unpack(‘m*’) : $2.unpack(‘M*’)}
end
file = File.open(filename,‘wb’) {|f|f.write(m.body)}
puts filename
end
end
end
end

The filename in the mime headers is just a filename - you need to join
that with a directory name same as you do when saving the email
itself.

Well you’ve already got
File.join(dir,email.subject)

for when you wanted a file in dir with the name email.subject, it’s
exactly the same this time except that instead of email.subject it’s
whatever you’ve extracted from the message part.
