# workaround, teach reloader to reload jobs
# if we do not do this then
#
# 1. on reload rails goes and undefines Jobs::Base
# 2. as a side effect this undefines Jobs::BotInput
# 3. we have a post_edited hook that queues a job for bot input
# 4. if you are not running sidekiq in dev every time you save a post it will trigger it
# 5. but the constant can not be autoloaded
