NoMethodError: undefined method `rule=' for nil:NilClass

[sebastiandeutsch]

Hi,

I'm trying out your gem and I'm getting an undefined method error with the following code (leaving recurring events aside for the moment):

event = calendar.events.where(uid: ical_event.uid.to_s).first_or_create
event.summary = ical_event.summary.to_s
event.description = ical_event.description.to_s

event.schedule.rule = "singular"
event.schedule.date = ical_event.dtstart
event.schedule.until = ical_event.dtend

event.save

These are my models:

class Event < ApplicationRecord
  acts_as_schedulable :schedule
end

class Schedule < Schedulable::Model::Schedule
end

Do I have to instantiate the schedule by myself - anything else that might be wrong?

Best

Sebastian
