Hi,
I''m trying to use a partial in my form (Rails 2.3.4), and the docs I
see
say I can do this:
edit.html.erb:
<% form_for(@course) do |f| %>
<%= render :partial => f %>
<p><%= f.submit "Update" %></p>
<% end %>
_form.html.erb:
<p>Title: <%= f.text_field :title %></p>
But when I go to the edit page I get an error:
undefined local variable or method `f'' for
#<ActionView::Base:0x465873c>
If I change the render line to be:
<%= render :partial => "form", :locals => {:f => f}
%>
it works, but the latest updates say I don''t need to do that.
Am I missing something?
Thanks.

I found that if I change my form partial to be: <%= form.text_field :title %> it works. I can live with that. But.. reading the updates to rails and forms and partials, it says you can shortcut it more by doing: <%= render @course %> I found that Rails will look for the partial named: _course.html.erb. Ok, I copied my form partial, but it doesn''t like any of my ''form helper'' variables - f.text_field, form.text_field, or course.text_field. Is this possible? thanks again -- Posted via http://www.ruby-forum.com/.
