My first guess, You don't have 'thumbnail' column in your database table. The clue is in the error message: 'find_or_initialize_by_thumbnail_and_parent_id', means attachment_fu looks for both 'thumbnail' and 'parent_id' column My db table looks something like this and it works fine. create_table :photos do |t| t.string :filename, :null => false t.string :content_type t.string :thumbnail t.integer :size t.integer :width t.integer :height t.integer :parent_id t.integer :album_id -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
