Rails - Oct 2005 - (no subject)

I''m stuck with a really basic single table inheritance question. I have
a table, people with the required ''type'' column and scaffolded
Person,
I edited the model (person.rd) to look like this:

class Person < ActiveRecord::Base
end

class Client < Person
  has_one :spouse
end

class Spouse < Client
  belongs_to :client
end

The controller for Person works fine but now how do I create/call the
CRUD for Clients and Spouses? Also do the inherited models need to be
identified somewhere in the application? Thanks. Hugh

Hugh,

I think the correct way to do this would firstly make Spouse < Person
instead of Client, unless all spouses are clients.

Secondly, move the declarations of the Client and Spouse models into
separate files (client.rb and spouse.rb).

Other than that, create a ClientController and just try it and see if it
works.  If it starts complaining about uninitialized constant Person
then you need to tell it where to look.  Either stick a line in your
controller that says ''model :person'' or in client.rb
"require ''Person''"

As for the crud stuff, you can either keep the controllers for Client
and Spouse unique (scaffolding or no), or you can inherit them from
PersonController.  Do note that you''ll still need to create views for
ClientController even if they exist for PersonController.
