that’s wrong. You probably meant Blog.find :all or Blog.find(:all)
(which are the same)

Well spotted Fred!
wouldn’t this be even easier though:
@blog = Blog.all

Hi! just briefly glancing over this but try adding ‘.id’ to the :id =>
on your form_for tag
So: <% form_for :blog, :url => { :action => ‘save’, :id => @blog.id }
do |f| %>
