Couldn't find without an ID

hi friends...
my rhtml is for_for_test.rhtml
<html>
  <head>
    <title>Form_For Tester</title>
  </head>
  <body>
    <% form_for :blog, :url => { :action => 'save', :id => @blog } do

f> %>

      Name: <%= f.text_field :blog %>
      <%= submit_tag 'Save' %>
    <% end %>
  </body>
</html>

controller is

def form_for_test
  @blog= Blog.find[:all]
  end
  def save
  blog = Blog.find(params[:id])
  blog.update_attributes(params[:blog])
  redirect_to :action => 'form_for_test'
  end

error msg: Couldn't find Blog without an ID

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| %>

Gavin

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
