# Caressing DelayedJob to work with Sinatra.
# I'm not sure if there is a gem for this or not, but i'm not a big fan
# of installing gems if i don't have to -- so heres what i found to be the
# bare foundation necessary to get delayed jobs running with sinatra
#
# 1. ./bin/delayed_job -- taken from the DJ gem's generator template but
# modified to point to this "environment" file rather than lib/environment
# 2. log/delayed_job.log -- DJ needs this
# 3. tmp/pids -- DJ needs this
# 4. Rails.logger -- DJ needs this
# 5. RAILS_ROOT -- DJ needs this constant defined
# 6. Delayed::Worker.backend = :active_record (or Delayed::Worker.guess_backend to guess)
# 7. migration file -- can take this from github or the gem's generator templates
#
# Debugging / Starting:
#
# 1. ./bin/delayed_job run
# 2. irb -r ./dj-sinatra.rb
# 3. tail -f log/delayed_job.log
#
# Console:
#
# Delayed::Job.enqueue SuccessfulJob.new # => should be clean in the logs/db table
# Delayed::Job.enqueue FailureJob.new # => should show failure message, etc.
