ruby - whenever gem is not working for every 2 seconds -

-

i have implemented whenever gem backend crons jobs working when try like

every 2.seconds   rake "my:rake:task" end

i error

`parse_time': time must in minutes or higher (argumenterror)

i want run task after every few seconds how can this.

you cannot whenever gem.

under hood, whenever gem creates cron job. these can configured @ minimum granularity of per-minute.

what could instead write shell script infinite loop runs task, , sleeps 2 seconds. however, advise against - running feels wrong. there's cleaner approach, e.g. running code after_save hook?
