Rails - Aug 2006 - after_create is not being called

Hi all

I have the following model:

class PhotoGallery < ActiveRecord::Base
  attr_accessible :title, :description, :file_path, :title_photo_id

  has_many  :photos, :dependent => :destroy
  belongs_to :title_photo,
          :class_name => ''Photo'',
          :foreign_key => ''title_photo_id''

  validates_presence_of :title, :description, :file_path

  def after_validation
    if !errors.invalid?("file_path")
      images = get_images
      if images.size == 0
        errors.add_to_base("There are no files in the directory 
#{get_images_path}")
      else
        errors.add_to_base(images.inspect)
      end
    end
  rescue SystemCallError
    errors.add_to_base("The directory #{get_images_path} does not 
exist")
  end

  def after_create
    if errors.empty?
      get_images.each do |image|
        photos.create :file => image.basename
      end
    end
    raise ="asdfasdfasdfa"
  end

  # some more stuff...
end

When I create a new photo gallery in the console, then after_validation 
is being called without any problem, but after_create isn''t! I got no 
idea why... :-(

Anyone has a clue? Thanks a lot.
Joshua

PS: I know, my Ruby style is still pretty bad... ;-)

Are you certain its getting created?

My gut reaction is that you have a before_create that is returning false....

I finally figured it out. The line

if errors.empty?

seems to return false, and so nothing happens. I removed the if 
statement, and now it works. Very strange although that the errors
don''t
seem to be empty...?! :O

And why didn''t the raise statement have any effect...?

Well, it works now, but I don''t really get it.
