Steve,
You are passing a block when you use the 'do' keyword. When you pass
a block into form_tag, it writes directly to the page.
As an rhtml example (because I think Haml formatting might get
clobbered when I send this):
<% form_tag whatever do %>
... fields, html, etc goes here
<% end %>
or,
<%= form_tag(whatever) %>
... fields, html, etc goes here
<% end_form_tag %>
So if you see the way I've not-used and used = there hopefully that
will help clear things up.
Cheers,
Brad
