Did you try adding a migration file like this one that I used:
class AddPhotoToTrick < ActiveRecord::Migration
def self.up
add_column :tricks, :photo_file_name, :string # Original filename
add_column :tricks, :photo_content_type, :string # Mime type
add_column :tricks, :photo_file_size, :integer # File size in
bytes
end
def self.down
remove_column :tricks, :photo_file_name
remove_column :tricks, :photo_content_type
remove_column :tricks, :photo_file_size
end
end
Try running a migration like that. My model is trick, rename tricks
appropriately.
