Tasks: TOP => resque:work => resque:preload

Works well. 😄 Thanks a lot.

This is an issue if you are adding Resque to a Rails app. As we know Resque does not require Rails. The solution allows you to load the entire Rails environment when you start up the workers. I did not see this issue when demoing Resque on a stand alone Ruby application.

And if you're using foreman, the corresponding syntax in your Procfile, that will also work, is

resque: bundle exec rake environment resque:work

In my case, I used .env to set my QUEUE environment variable:

QUEUE='*'

thank you for this!
