Rails - Sep 2006 - newbie Q: it won't display foreign keys...

I have two tables

CREATE TABLE continents (
  id int(11) NOT NULL auto_increment,
  name varchar(255) NOT NULL,
  PRIMARY KEY  (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;


CREATE TABLE countries (
  id int(11) NOT NULL auto_increment,
  name varchar(255) NOT NULL,
  continent_id int(11) NOT NULL,
  PRIMARY KEY  (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;


I generate scaffolds for country and for continent

I modify the models and add belongs_to and has_one:

class Continent < ActiveRecord::Base
    belongs_to :country
end

class Country < ActiveRecord::Base
      has_one :continent
end

The code that is generated to show a country record is

<% for column in Country.content_columns %>
<p>
  <b><%= column.human_name %>:</b> <%=h
@country.send(column.name) %>
</p>
<% end %>

<%= link_to ''Edit'', :action => ''edit'',
:id => @country %> |
<%= link_to ''Back'', :action => ''list''
%>


This latter code does NOT display the field continent_id (or
continent.name as I would like)

Do I need to rewrite the code so that every individual field that needs
to be displayed is generated separately. and for teh foreign keys I
generate appropriate code or can the loop for column in be modified?

I also can''t find the documentation for the send method in
@country.send(column.name). Can someone give me a hint?

Thanks,

Ruud

Hi Ruud,

Scaffolding isn''t meant to be used as end, all code, 99.9% of the  
time you will have to mod it to your liking.

also....

http://www.ruby-doc.org/core/ -> check out the send method in the  
object class
