Hi Peter,
Many thanks for your extensive help on this one. I now have
@project_file = ProjectFile.new(params[:project][:uploaded_data])
in my projects controller.
<%= f.file_field :uploaded_data %>
but it still says
ActiveRecord::UnknownAttributeError in ProjectsController#create
unknown attribute: uploaded_data
