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
