Send mail only when a condition satisfy


#1

I would like to send a digest of what have been changed in a day to
some admins. However, some day there won’t be any change. How do I not
send emails on such cases?

Currently, my mailer is called Postoffice. I call
Postoffice.deliver_daily_digest every night by a cron job.

Inside of daily_digest method, I have queries to figure out what have
been changed. I don’t want to repeat these queries in my rake task.
Any suggestions would be appreciated.

I would extract those queries from the mailer into some other class
(eg DailyReporter).
The mailer is then just something dumb which inserts data passed to it
in various parts of the template

Usage might look like

report = DailyReporter.run
if report.anything_happened?
Postoffice.deliver_daily_digest(report)
end
