Ruby on Rails - basic mailer in ruby on rails - ruby on rails tutorial - rails guides - rails tutorial - ruby rails
Example
- Uses four different files:
- The User model
- The User mailer
- The html template for the email
- The plain-text template for the email
This case, the user model calls the approved method in the mailer and passes the post that has been approved (the approved method in the model may be called by a callback, from a controller method, etc). Then, the mailer generates the email from either the html or plain-text template using the information from the passed-in post (e.g. the title). By default, the mailer uses the template with the same name as the method in the mailer (which is why both the mailer method and the templates have the name 'approved').
user_mailer.rb
class UserMailer < ActionMailer::Base
default from: "donotreply@example.com"
def approved(post)
@title = post.title
@user = post.user
mail(to: @user.email, subject: "Your Post was Approved!")
