# This class lets you enqueue class methods with Delayed Job
# For Rails, name this delayed_profit.rb and put it in your app/models directory
# For the others, do what you do to load files
# Usage: Assuming Notifier is your ActionMailer class then ...
#   Delayed::Job.enqueue DelayedProfit.new(Notifier,
#     :deliver_profit_notification, 'hey!', 'we profitted')
#   This causes Delayed Job to execute
#     Notifier.deliver_profit_notification('hey!', 'we profitted')
class DelayedProfit

  def initialize(klass, send_method, *params)
    @klass = klass.to_s
    @send_method = send_method
    @params = params
  end

  def perform
    @klass.constantize.send(@send_method, *@params)
  end
end

# As a side note, if you are going to use this  with ActionMailer models,
# I suggest you NOT pass in models but instead pass in the ids of the models
# and do the Model.find(id) from inside the ActionMailer model's method
