Rails4 Mongoid Paperclip does not upload file, but everything else

Question

I have a Rails4 Project Using Mongoid and Mongoid-Paperclip. I have ImageMagick just set up and the commands seem to work. The Model, that holds the image gets created, all the image fields get filled. The only thing that does not work is the copying of the files to the public/system/... folder (In development mode on my mac).

Here is the Code and output:

Catalog Image (embedded by Part)

class CatalogImage
  include Mongoid::Document
  include Mongoid::Paperclip

  field :caption

  embedded_in :part, inverse_of: :catalog_images
  has_mongoid_attached_file :image,
      :path => ":rails_root/public/system/:attachment/:id/:style/:filename",
      :url => "/system/:attachment/:id/:style/:filename",
      :styles => { :small => "200x200>", :medium => "500x500>" }
  validates_attachment_content_type :image, :content_type => %w(image/jpeg image/jpg image/png)
end

Part (Embeds many catalog images)

class Part
  include Mongoid::Document
  field :name
  field :description
  field :price
  field :clickout

  embeds_many :catalog_images

  accepts_nested_attributes_for :catalog_images

end

Gemfile

...
gem 'mongoid', '4.0.0.beta1', github: 'mongoid/mongoid'
gem 'bson_ext'

gem "mongoid-paperclip", :require => "mongoid_paperclip", :git => "git://github.com/meskyanichi/mongoid-paperclip.git", :branch => "develop"
...

Output

Files in embedded documents are not saved when the parent is saved. Meaning you can't persist files unless you explicitly tell it to. In your case:

embeds_many :catalog_images, cascade_callbacks: true

From https://github.com/meskyanichi/mongoid-paperclip

Note on embedded documents: if you plan to save or update the parent document, you MUST add cascade_callbacks: true to your embeds_XXX statement. Otherwise, your data will be updated but the paperclip functions will not run to copy/update your file.

This did not work for me, but still, your answer made me fix it. I had to add "cascade_callbacks" to the "embeds_many" line: `embeds_many :catalog_images, cascade_callbacks: true` – Stefan Feb 19 '14 at 12:41
@Stefan - Thanks. That was a mistake. Fixed my answer :) – veritas1 Feb 19 '14 at 12:47

Thanks to veritas1 I was able to fix it. I had to add "cascade_callbacks = true" to the "embeds_many" line.

class Part
  include Mongoid::Document
  field :name
  field :description
  field :price
  field :clickout

  embeds_many :catalog_images, cascade_callbacks: true

  accepts_nested_attributes_for :catalog_images

end
