Markerb allows you to render multipart e-mails from a single template. The template is written in Markdown, which is delivered as a text part, but also rendered and delivered as an HTML part.
The usage is quite simple. Assuming you have a notifier as below:
class Notifier < ActionMailer::Base def contact(recipient) @recipient = recipient mail(:to => @recipient, :from => "firstname.lastname@example.org") do |format| format.text format.html end end end
If you create a template at app/views/notifier/contact.markerb:
Multipart templates **rocks**, right <%= @recipient %>?!
It will generate two parts, one in text and another in html when delivered. Before we finish, here are a few things you might need to know:
The “contact.markerb” template should not have a format in its name. Adding a format would make it unavailable to be rendered in different formats;
The order of the parts matter. It is important for e-mail clients that you call format.text before you call format.html;
Notice you can normally use ERb inside the template.
