How to use Quantum?
Am new to Elixir and i need help how to schedule a task…
defmodule PluralsightTweet.Scheduler do
def schedule_file(schedule, file) do
Quantum.add_job(schedule, fn -> IO.puts PluralsightTweet.FileReader.get_strings_to_tweet(file) end)
end
end
this is the error am getting:
Quantum.add_job(“* * * * * * “, fn-> IO.puts “test” end)
** (UndefinedFunctionError) function Quantum.add_job/2 is undefined or private
(quantum) Quantum.add_job(” * * * * * *”, function<20.99386804/0 in :erl_eval.expr/5>)

That’s not how you must use Quantum, follow their documentation on: https://hexdocs.pm/quantum/readme.htm
More details:
Quantum.add_job/2is not a function, maybe what you mean isQuantum.Scheduler.add_job/2Quantum.Scheduler.add_job/2is not a function also, and yes a callback that should be defined by the modules that use@behaviour Quantum.Scheduler
My impression is that you may be confusing what the lib quantum really is. It’s not a job scheduler like, for example, sidekiq, what it does is something like what the command line tool cron does, scheduling recurrent executions.
