ActionMailer Cheatsheet
ActionMailer is the Rails framework which handles email delivery. This comprehensive cheatsheet will help your email on its way.
- Mailer Model - emails are defined by creating methods within the mailer model
- Delivering email - deliver emails or create and save them for future delivery
- Multipart messages - how to send multipart messages
- Views & Templates - each mailer has a corresponding view
- Mailer Configuration Methods - use in your mailer model to define an email
- URL Generation - generate URLs to be used in your mailer view template
- ActionMailer Configuration - configure Action Mailer
Delivering mail
Once a mailer action and template are defined, you can deliver your message or create and save it for delivery later by calling the mailer class and prefixing your chosen class method with deliver_ or create_
Send mail
Notifier.deliver_signup_notification(customer)
Create mail
mail = Notifier.create_signup_notification(customer) Notifier.deliver(mail)
You can pass the mailer model any variables you need to use in the generation of the email. In the example above we have passed it a variable named customer which could be an instance of an ActiveRecord Customer model. We can then access our customer's details in the mailer model.
