Aha! Posting the full error text led me to read it more carefully. There's a line in there that says:
app/helpers/listings_helper.rb:3:in `add_image_link' Looked in add_image_link, which is a helper that dynamicall adds more copies of the same partial. Needed to add the local variables there too, and now all is golden! Thanks again for your help. def add_image_link(name) link_to_function name do |page| page.insert_html :bottom, :attachments, :partial => 'listings/ attachment', :object => Attachment.new, :locals => {:foo => "bar"} end end --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
