I have a polymorphic class named \"Asset\" that have :

Answer 1

Something like this in the url:

:url => "/attachments/:path/:basename_:style.:extension",  

then in the interpolations:

Paperclip.interpolates :path do |attachment, style|
  if attachment.instance.file_owner_type == User.class.name
    # first set the _user variable (something like self.owner.id.to_s) 
    return "user_" + _user
  else
    # first set the _user, _dressing, _garmet, _category variables from your models
    return "user_#{_user}/dressing_#{_dressing}/garment_#{_garmet}/category_#{_category}/"
  end
end

Notice that you need to set the _user, _dressing, _garmet, _category variables from your models.

Hope this helps.

Try: attachment.instance.file_owner.class.downcase in your defined interpolation.
