[iCalendar-devel] Question about using iCalendar in rake tasks

First, thanks for making iCalendar - I can''t imagine having to do this
from
scratch!

I have a question I was hoping someone can help me with. I use iCalendar in
one of my Rails models to generate iCalendar files when certain types of
objects are created. This works fine within my Rails application, but I
recently had the need to invoke one of the finders in the model through a
rake task. The method called by the rake task never uses any iCalendar
functionality, but when I invoke the task, I get the following error:

$ rake appointment:upcoming_reminder --trace
(in /Users/chris/dev/ss)
** Invoke appointment:upcoming_reminder (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute appointment:upcoming_reminder
rake aborted!
undefined method `all'' for Icalendar::Event:Class
/Users/chris/dev/ss/app/models/event.rb:57:in
`findEventsTomorrowForEmail''
/Users/chris/dev/ss/lib/tasks/notification.rake:6
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rake-0.8.3/lib/rake.rb:617:in
`call''
...

The referenced line of the event model file is the invocation of a custom
finder. Also within that model I require and include icalendar. Is it
possible that somehow the include of Icalendar is causing this rake problem?
Is there a way around it?

Any suggestions are appreciated!

Thanks,
Chris

I''m relatively new to creating rake tasks so I''m at a bit of a
loss as to
why this is happening. Could it have something to do with the

[iCalendar-devel] Question about using iCalendar in rake tasks

That''s a new one that I''ve not seen before, can you share the
code that
is triggering this?  My guess it that something is empty or nil that you 
aren''t expecting, and that''s causing the issue.

[iCalendar-devel] Question about using iCalendar in rake tasks

Sure Sean. My model code (with a couple model names made generic by
find/replace):

require ''rubygems''
require ''icalendar''
require ''date''

class Event < ActiveRecord::Base
  include Icalendar

  belongs_to :model1
  belongs_to :model2
  belongs_to :model3
  belongs_to :model4

  attr_accessible :model4

  after_save :sendIcalEmail

  def sendIcalEmail
    logger.debug "in sendIcalEmail"
    if (!self.customer.nil? && self.customer.emailReminders == true)
      #icalEvent = Icalender::Event.new
      #icalEvent.start = DateTime.parse(self[:startTime])
      #icalEvent.summary = summary "Appointment with " +
self[:model3].fullName + " for " + self[:model4].description
      evstart = startTime.to_datetime
      evend = endTime.to_datetime
      evsummary = "Appointment at " + self.name
      cal = Calendar.new
        cal.event do
          dtstart       evstart
          dtend         evend
          summary       evsummary
          location
          alarm do
                action        "DISPLAY" # This line isn''t
necessary, it''s
the default
                summary       evsummary
                trigger       "-P1DT0H0M0S" # 1 day before
          end

        end


      #cal.add_event(icalEvent)
      #logger.debug cal.to_ical
      CustomerNotifier.deliver_eventNotification(self.customer.email,
cal.to_ical)
      logger.debug cal.to_ical
    end
  end


  def self.findEventsTomorrow
    tomorrow = Time.now.strftime("%Y-%m-%d")
    Event.all :joins => [:model1, :model2, :model3, :model4], :conditions
=>
["startTime LIKE ?", "#{tomorrow}%"]
  end

  def self.findEventsTomorrowForEmail
    tomorrow = Time.now.strftime("%Y-%m-%d")
    nextDay = (Time.now + 1).strftime("%Y-%m-%d")
    #Event.all :joins => [:model1, :model2, :model3, :model4], :conditions
=>  ["startTime > #{tomorrow} and endTime < #{nextDay} and
emailReminders 1" ]
  end

  def self.findEventsTomorrowForSMS
    tomorrow = Time.now.strftime("%Y-%m-%d")
    nextDay = (Time.now + 1).strftime("%Y-%m-%d")
    Event.all :joins => [:model1, :model2, :model3, :model4], :conditions
=>
 ["startTime > #{tomorrow} and endTime < #{nextDay} and smsReminders
= 1" ]
  end

end

And the rake task:

namespace :appointment do
  desc "Sends upcoming appointment reminders to clients"
  task :upcoming_reminder => :environment do
    events = Event.findEventsTomorrowForEmail
    print "Sending upcoming appointment reminders"
    events.each do |e|
      print e.startTime + " " + e.endTime + " " +
e.customer.email
    end
  end
end

Thanks for your help,
Chris

[iCalendar-devel] Question about using iCalendar in rake tasks

I may have found a clue on this. If I change the methods in the model to
"self.find" or "self.all" instead of using the model name
(Event.find/Event.all), it works fine.

I''m relatively new to Ruby so I''m not exactly sure why this
matters. (Either
work fine if I comment out ''include Icalendar''.) Is it
possible that methods
invoked with Event.* are somehow getting picked up by the Icalendar module
due to the include? Thinking that this may be the case, I tried adding the
following to the Icalendar module but that didn''t solve the problem:

    def self.included(base)
      base.extend(ClassMethods)
    end

I''m glad I have a workaround, but I''d still like to understand
why this
happened. If anyone has any ideas, I''d appreciate it. Thanks!

Chris
