Model-Conductor-Controller fix

Written on 11:42:00 AM by S. Potter

The New Bamboo blog talked about Presenters & Conductors last month. The demonstration Rails application was broken, so the enclosed link to a zip file contains the fixes I made to get the application running as expected. The offending code was in lib/action_conductor/lib/action_conductor/errors.rb:

module ActiveRecord
  class Errors
   def add_conductor_errors_for(record, mapping)
    return if record.valid?
    record.errors.each do |attribute, message|
      self.add(mapping[attribute.to_sym], message)
    end
   end
  end
end

The fixed code changed one line as so:

module ActiveRecord
  class Errors
   def add_conductor_errors_for(record, mapping)
    return if record.valid? or record.new_record?
    record.errors.each do |attribute, message|
      self.add(mapping[attribute.to_sym], message)
    end
   end
  end
end

The fixed zip file can be found at my 4shared account and also fixes the minor view errors.
