HI, Having just installed attribute_fu I''m getting the error ArgumentError in DogsController#new Unknown key(s): attributes, discard_if I assume this is coming from my model has_many parameters :attributes => true, :discard_if => proc { |upload| upload.photo_file_size.nil? I can only assume that I need an include or some path option somewhere or I havent set up attribute_fu properly? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
