How do I return values when using form_for


#1

Hi I am trying to build a simple app where I’m trying to do pretty what
scaffold does. My question is when I am using ‘form_for’ how do I return
the id while editing the application like its done in the form_tag

for example

Editing book

<% form_tag :action => ‘update’, :id => @book do %>
<%= render :partial => ‘form’ %>
<%= submit_tag ‘Edit’ %>
<% end %>

<%= link_to ‘Show’, :action => ‘show’, :id => @book %> |
<%= link_to ‘Back’, :action => ‘list’ %>

Here the :id=>@book sends the id back so that i can find it in my
controller before i update it similarly how can i send something back
with the form_tag without using the hidden tags.
