Receiving emails
Listing 12.14 app/mailers/notifier_spec.rb
require "spec_helper"
describe Notifier do
it "correctly sets the reply-to" do
comment = Factory(:comment)
mail = ActionMailer::Base.deliveries.last
mail.from.should eql(["youraccount+#{comment.project.id}+" +
"#{comment.ticket.id}@example.com"])
end
end
Here you test that the from for the latest email sent out contains the ids of the project
and ticket related to the comment you create. With this information contained in the
email address, you’ll be able to know what project and ticket to create the comment
for when a user replies to that email.
When you run this spec using bin/rspec spec/mailers/notifier_spec.rb, you
see that you need to define the comment factory:
No such factory: comment (ArgumentError)
Let’s define this new factory in factories/comment_factory.rb like this:
Factory.define :comment do |comment|
comment.text "A plain old boring comment."
comment.ticket { |t| t.association(:ticket) }
comment.user { |u| u.association(:user) }
end
Now when you run bin/rspec spec/mailers/notifier_spec.rb, you see that it fails
with this error:
expected ["ticketee+1+1@gmail.com"]
got ["ticketee@gmail.com"]
Right then! A failing test is a great place to begin, and now you need to fix it. Let’s
open app/mailers/notifier.rb and add a :from option to the mail call inside the
comment_updated method:
:from => "Ticketee "
This will change the “from” address on emails that go out to your users by tagging the
addresses with the project and ticket id. When the user replies to this email, you can
use this tag to find the project and ticket that you need to create a new comment on.
Let’s run bin/rspec spec/mailers/notifier_spec.rb again to see it pass:
1 example, 0 failures
Now you need to work on the actual receiving of replies directed at this tagged
address!
