Rails - Feb 2006 - ActionMailer - ROR Recipes - Multipart/alternative

I am using the SaltedHashLoginGenerator. and would like to send the e-mail in
multipart/alternative format.
  
  By default my application is using forgot_password_en.rhtml template.
  
  I read in the ROR Recipes book
  
  "ActionMailer sees these templates, recognizes the pattern in their
  file names, and automatically sets the MIME type of the message to
  multipart/alternative and adds each rendered view with the content type
  in its file name."
  
  So I created  forgot_password_en.text.plain.rhtml template and 
forgot_password_en.text.html.rhtml templates (and removed the 
forgot_password_en.rhtml template temporarily).
  
  Now my application won''t send any email.
  
  How can I make ActionMailer recognize these templates and set the appropriate
MIMe type?
  
  
  My mailer function looks like this:
  
    def forgot_password(member, url=nil)
      setup_email(member)
  
      # Email header info
      @subject += "Forgotten password notification"
  
      # Email body substitutions
      @body["name"] = "#{member.firstname}
#{member.lastname}"
      @body["login"] = member.login
      @body["url"] = url || MemberSystem::CONFIG[:app_url].to_s
      @body["app_name"] = MemberSystem::CONFIG[:app_name].to_s
    end
  
  
  Thanks for your assistance.
  Frank

Hi Frank.

Would this work if your templates weren''t called "_en"?  I
believe
ActionMailer requires the template to be named _exactly_ the same as the
mailer''s method (forgot_password) with the remaining dot-separated
parts of
the name representing the mime type and template type (eg .rhtml).

So if you rename your templates to, for example,
forgot_password.text.plain.rhtml does your mailer start working again?

Hello Chad,
  Thank you for your reply. I will certainly follow your tip and post the 
results here. It sounds like it should work, but I will let you know.
  
  Thanks

I used SHLG and it generated a "forgot_password" method in my
MemberNotify ActionMailer
subclass and a "forgot_password_en.html" view. That all appears to
work.

Sorry I can''t offer any insight on why things aren''t working
-- I''m still very new to all
this -- but I thought I should point out that the "_en" isn''t
breaking mine. I''m fairly
certain that''s added by the Localization plugin.

Yea, my bet is (I don''t know the localization plugin well) that the
localization plugin overrides the view-finding logic in a way that
doesn''t affect the hardcoded checks that happen in the ActionMailer
code.  It might be worth a patch to ActionMailer to make it more
flexible if that''s the case (or maybe not).

Dear Chad,
  
  Thank you for your assistance.
  
  I tried renaming as per your suggestion and tried resending email but the
email delivery failed.
  
  Then I looked in the localization code and found the following code in 
lib/localization.rb which is responsible for adding the _en to the  template
name:
  
    # redefinition of ActionMail::Base#render_message, that adds locale suffix
to
    # the template name
    ActionMailer::Base.module_eval <<-EOL
    private
    def render_message(method_name, body)
      initialize_template_class(body).render_file(method_name +
"_#{CONFIG[:default_language]}")
    end
    EOL
  
  I commented the entire code out, restarted the server and tried again and
voila!, it worked.
  
  My forgot password message arrived with content-type set to:
  
  multipart/alternative; boundary=mimepart_43e8db39b433c_1a4a..fdbaf1bcc3c9

  Seeing how many folks are using SLHG, I highly recommend the addition  of
following tips as the addition of these will highly benefit your  readers:
  
  1. How to modify the above code to keep the localization but still be able to
use multi-part messages.
  2. How to specify a reply_to address for ActionMailer. (I still cannot figure
it out)
  3. How to specify content type of text/html without using multipart for SLHG
(by using @content_type="text/html")
  
  The SLHG works great, though it does takes some time. I have finally 
integrated it and recommend that it be added to the recipes also. The 
documentation that comes with SLHG is pretty self explanatory but can  be
overwhelming.
  
  What editor did you use to compose the book? Docbook or something else?
  
  Thank you once again for your assistance and great tips.

gemologists to stand out from the rest.

I''m using the Pragmatic Programmers'' proprietary (and
