Need to run timer-based tasks, but you have no control over your cron? Heroku's hourly cron got you puzzled? Wristwatch is here to help.
Tell it what to do in config/wristwatch_jobs.rb, and which intervals to use,
and Wristwatch does the rest:
hourly "Flush unsent emails" do
Notifier.flush_unsent
end
daily "Reindex Solr" do
Rake::Task['sunspot:reindex'].execute
end
daily "Send reminder emails" do
Notifier.remind_users_to_call_mom
end
Wristwatch gives you lots of basic intervals to play with:
- hourly
- bi-hourly
- quarter-hourly
- bi-daily
- daily
- weekly
- bi-monthly
- monthly
and so on. See intervals.rb for details, and re-open it to add your own task triggers.
Wristwatch will add a cron.rake task if you're using Rails, which should make it easy to plug in to Heroku's hourly cron.
Wristwatch relies on hourly resolution, so daily cron probably won't trigger the :daily task. For best results, run cron.rake hourly.
Full configuration, logging, increased resolution and more. Stay tuned!
