Picture the to-do editor in Backpack (and, to a lesser extent, Basecamp) and you''ll have a good idea of what I''m trying to do.

I am trying to use SVN HEAD of Acts_as_ferret, and I have ferret 0.10.4installed from the windows Gem. Unfortuanantly, whenever I i let act_as_ferrets init.rb file require ferret, my app blows up, with weird "Invalid char" errors. I have pasted the page below.

Hi guys, I was wondering if you are able to have a link_to_remote, having an image_tag and the link_to_remote has a mouseover event that updates a div. Does the image_tag need the mouseover event? I currently have: <%= link_to_remote(image_tag(@p_image.public_filename(:thumb)), :update => "big_pic", :onmouseover => {:action => :color_change, :id => @p_image.id})%>

Hello! I am working my way through the Agile Web Development guide on RoR (the depot application). I am a bit lost as to where to debug the following error. The error is pasted below: ================================================================================================ NameError in Store#add_to_cart undefined local variable or method `product'' for LineItem:Class
