resque-schedular undefined method enqueue_at

initializers\resque.rb must reference resque_schedule.

require 'resque_scheduler' 

resque task must be started

COUNT=5 QUEUE=* rake resque:workers

resque-schedule task must be started

rake resque:scheduler

to monitor resque-schedule, resque-web must be started with the config file of resque as parameter. This one must not reference anything from rails directly as resque-web is a sinatra app and it won't be able to load it properly.

resque-web ~/pathToYourApp/config/initializers/resque.rb
