Ah, yes. Sorry about that. The radio_group method isn't a part of the
FormBuilder, so while you can still call it within the scope of the form_for
block, you can't call it the way I told you to.
You will need to call it similar to:
<%= form_for @post do |f| %>
...
<div>
<%= radio_group "post[postType_id]", PostType.all(:order => "name
ASC").map {|pt| [ pt.id, pt.name ] }
</div>
...
<% end -%>
This *should* work if you adjust the code to your particular situation, but
post back if not.
