resque_action_mailer_backend_example¶ ↑

This is the example application for the resque_action_mailer_backend gem. The changes made into this application to get it’s emails to be sent over using Resque were creating the lib/tasks/resque.rake file and then defining the resque:setup task as requiring the environment task that loads the Rails environment. This file should require the resque tasks file, below:

#lib/tasks/resque.rake
require 'resque/tasks'
namespace :resque do
  task :setup => :environment
end

Then, in the config/environments/development.rb file the email delivery method was changed to :resque and, finally, in the environment.rb file the resque_action_mailer_backend gem is required with:

config.gem "resque_action_mailer_backend"

If you’re going to use this application for testing, you should add your email configuration at config/initializers/email_config.rb, then you can start a resque worker with:

rake resque:work QUEUE=* VERBOSE=1

And then you can send a test email with:

script/runner "Mailer.deliver_test"

The email will show up at the Resque worker console and you’ll recive it as soon as the worker finishes sending it.

Resque and the append only rolling file¶ ↑

If you’re using the default Redis configuration, you’re probably using the append only file as a backup for your Redis dabase. As the name implies, the file is append only so once you get contents in there, they’ll never be removed and this will make the file grow bigger until it blows your hard drive.

Obviously, it’s going to take some time for something like this to happen, but with emails being sent things could change so you should be safe and setup a cron job running the code that tells Redis to rebuild the file with the current memory state. This is done by sending the BGREWRITEAOF command to Redis and this project already includes the scripts/redis_rebuild file that does just that so you don’t even have to worry about writting it, just setting up the cron job.
