Install theme from ActionMailer template in Rails 3?

Question

How to set an object from an ActionMailer Rails 3 template?

I would like to keep the subject and body together.

In Rails 2, you can do the following:

<% controller.subject = 'Change of subject' %>

Answer 1

http://edgeguides.rubyonrails.org/action_mailer_basics.html

it says that:

 class UserMailer < ActionMailer::Base default :from => "[e-mail]" def welcome_email(user) @user = user @url = "http://example.com/login" mail(:to => user.email, :subject => "Welcome to My Awesome Site") end end 

If you want to access it from a view:

If you need to access an item, from or to recipients in a view, you can do this through the message object:

  You got a new note from <%= message.from %>! <%= truncate(@note.body, 25) %> 

So you can do:

 message.subject 

Answer 2

To set the subject line of an email message directly from the email view, you can simply put the following at the beginning of a file of the form:

 <% message.subject = 'This is my subject line' %> 

This works for rails 3 and 4.
