Sending email
In the previous chapter, you implemented tagging for your application, which
allows users to easily categorize and search for tickets.
In this chapter, you’ll begin to send emails to your users. When a user signs up
to Ticketee, they use their email address as a way for the system to uniquely identify
them. You then verify that the address is valid by sending the user a confirmation
email. With a user’s validated email address, you’re able to send them updates for
important events in the system, such as a ticket being updated.
Back in chapter 6, you changed a setting for the authentication engine Devise
that would send a confirmation email to a new user when they signed up. To test this
setting, you used a gem called email_spec, which only tested that the emails were
delivered in a test environment, and not in the real world. This is how Action Mailer
(the Rails component responsible for email) acts 1 during a test environment.
1 It defaults to not truly sending out the emails, but rather keeping track of them in a variable that you can
access by using ActionMailer::Base.deliveries, or by using the methods found in email_spec.
