Real-world email
Great! Now you have a way for users to toggle their watch status on any given ticket.
Let’s make sure that everything is working by running rake cucumber:ok spec. You
should see the following output:
62 scenarios (62 passed)
717 steps (717 passed)
# and
40 examples, 0 failures, 20 pending
Everything is still A-OK, which is good to see. Let’s commit this change:
git add .
git commit -m "Add button so users can toggle
watching on a ticket"
git push
You’ve now got a way that a user can start or stop watching a ticket. By watching a
ticket, a user will receive an email when a comment is posted to the ticket. You’re
doing great in theoretically testing email, but you haven’t yet configured your application
to send out emails in the real world. Let’s do that now.
12.3 Real-world email
You’ve just created the beginnings of a way to send email in your application, but
there’s still a part missing: the SMTP server that receives your mail objects and then
sends them out to their recipients. You could spend a lot of time configuring one
yourself, but many companies offer a free SMTP service, such as Gmail. 8 You’ll use a
Gmail account to send out tests of your emails, and you can use Action Mailer to connect
to this service.
WARNING You wouldn’t use Gmail to send or receive your emails if you
were running a much larger application, but rather another web service
such as SendGrid. This is because Gmail has a limit of about 200 sent
emails a day, and if there are 200 tickets updated in a single day then it’s
goodbye email cap. Gmail is great for light email usage, but if you want to
scale up your usage, SendGrid is one of the best options out there.
Action Mailer has a setting that you can use to set up your SMTP connection:
ActionMailer::Base.smtp_settings = {
:username = "youraccount@example.com",
:password = "yourpassword"
...
}
Before you dive into setting this up, you’re going to need a feature to ensure that it
always works. When you set up your application to send emails in the real world, it
may work from the get-go, and you can test it manually by sending out emails in your
8 SendGrid offers one too that you would use, but you’re going to need to receive emails next, and having a
Gmail account will allow you to do that.
