Hi Cool,

Obviously the above 'person' and 'principal' are capitalized.

yes

Not much point doing this if you don't include the parameter. Also,
where is your form posting to?
<% form_for :student , :url => {:action => 'update'} do |s| %>
> <td><%= text_field :first_name, :label => "Student" %>
> <td><%= text_field :last_name %></td>
Then you can say:
<td><%= s.text_field :first_name, :label => "Student" %>
Or
<td><%= text_field :student , :first_name, :label => "Student"
%>
which is the same thing.

You don't need "fields_for" - I don't think you're using it below.

So instead, it would be something like:
<td><%= text_field :parent , :first_name, :label => "Parents/
Guardian" %></td>
And similarly for the rest of these:
> <td><%= text_field :last_name %></td>

See my previous post if you want a dropdown selection box; ie <%=
select ... %>.

ok; you could probably even omit creating these.

ok

So:
<td><%= text_field :parent , :first_name, :label => "Parents/
Guardian" %></td>
will create something like
<input type="text" name="parent[first_name]" ... />
The important thing is the name attribute.
It will be converted to
params[:parent][:first_name]
etc
Similarly for principal:
<td><%= text_field :principal , :first_name %></td>
So in your update action of your controller, you then say:
@parent=Parent.new(params[:parent])
and similarly for @student and @principal.
