Subscribing to updates Listing 12.5 features/ticket_notifications.feature Scenario: Comment authors are automatically subscribed to a ticket When I follow "TextMate 2" And I follow "Release date" And I fill in "Text" with "Is it out yet?" And I press "Create Comment" Then I should see "Comment has been created." When I follow "Sign out" Given a clear email queue Given I am signed in as "alice@ticketee.com" When I follow "TextMate 2" And I follow "Release date" And I fill in "Text" with "Not yet!" And I press "Create Comment" Then I should see "Comment has been created." Then "bob@ticketee.com" should receive an email Then "alice@ticketee.com" should have no emails In this scenario, you’re already logged in as bob@ticketee.com (courtesy of the Background). With Bob, you create a comment on the “Release date” ticket, check that alice@ticketee.com receives an email, and then sign out. Then you clear the email queue to ensure that alice@ticketee.com receives no emails after this point. You sign in as alice@ticketee.com and create a comment, which should trigger an email to be sent to bob@ticketee.com, but not to alice@ticketee.com. When you run this scenario using bin/cucumber features/ticket_notifications.feature:36, you see that Bob never receives an email: expected: 1, got: 0 (using ==) (RSpec::Expectations::ExpectationNotMetError) ... features/ticket_notifications.feature:54 This is failing on the step that checks if bob@ticketee.com has an email. You can therefore determine that bob@ticketee.com isn’t subscribed to receive comment update notifications as he should have been when he posted a comment. You need to add any commenter to the watchers list when they post a comment so that they’re notified of ticket updates. 12.2.2 Automatically adding a user to a watchlist To keep users up to date with tickets, you’ll automatically add them to the watchers list for that ticket when they post a comment. You currently do this when people create a new ticket, and so you can apply the same logic to adding them to the list when they create a comment. You can define another after_create callback in the Comment model by using this line: after_create :creator_watches_ticket 327
328 CHAPTER 12 Sending email Next, you need to define the method that this callback calls, which you can do by placing this code at the bottom of your Comment model: def creator_watches_ticket ticket.watchers
