Question

I have a rails project that I would like to set up email notifications for. For example, if record X expires in 5 days, send an email to the owner. I have email notifications set up when new users register but can’t figure out how to send email based on a conditional (if x = y, then send email). Please help!!

You can use rake tasks for it. Set it in cron to execute once a day.

Example rake task code you can modify and use:

task :send_reminds => :environment do
  Record.all.each do |remind|
    UserMailer.remind_email(record).deliver if record.expires_in(5.days)
  end
end

Make new bash script, put it wherever you want:

#!/bin/bash
cd /your/path/to/rails/app
rake send_reminds

Use crontab -e to add your task to crontab. Add this line:

0 0 * * * /your/path/to/bash/script

It will execute it each day at midnight.

Remember to set chmod +x to the script!
