Dynamic subject in Mandrill e-mail using rails

Question

I have passed dynamic content to the body of the email. But looking at the API docs the subject params only accepts a string and not an array.

Is there a way to pass a dynamic subject? I would like to pass the name of the recipient in the subject

I have the following right now:

    m = Mandrill::API.new ENV['MANDRILL_APIKEY']
message = {
:subject=> template.subject,
:from_name=> template.name,
:from_email=> template.from + "@" + email_domain,
:to=>mails,
:global_merge_vars=> [
  { :name => 'IMAGE', :content => image_tag},
      ],
:html=>email_template,
:preserve_recipients => false,
:merge_vars => variables, 
}

Answer 1

It seems that Mandrill reads merge variables in the subject as well. So it is as simple as adding *|SOME_VAR|* in your subject text and then passing it as a parameter in the merge_vars.
