Is there a simple way to edit two tables with a has_many/belongs_to
relationship? I have a very typical parent table (Departments) with
an id, name, description, etc. And I have a child Resources table
with an id, department_id, title, description, and other fields.
I want to allow a user to edit the child table but I see that the
standard behavior for scaffolds is to suppress displaying key fields
(primary and foreign) is there a way to override this?
Basically when I'm editing the child record I really need to display
the Department.title. I know I can do this by hand, but I'd like
the scaffolding to help me if possible! is it?
Check out the 3-part screencast on complex forms at railscasts.com
starting with #73
This will walk you through setting up editing two forms at once if you
want something more complex.

or just In your Resources (that's the child right?) view, use this in
your _form
<%= collection_select :resource, :department_id,
Department.find(:all), :id, :name %>
Read more about collection_select here:
it puts in department_id of a resource from what was collected from
all department listings and give you a select field with id of
department as a value and name of department as text.
and in your list use <%= resource.department.name %> inside the for
statement, and in show <%= @resource.department.name %> anywhere.
