Database Foreign Key - Basic question

Rails
1

Hi all

I’m still waiting on my Agile Rails book to arrive - in the meantime …
As an exercise I’m making a Help Desk application.
If I have a Problems table with two foreign keys to a People table,
how do I set up my models, problems_controller list method, and then
simply display say my problem submitter person? Here is what I have so
far:

Problems table with columns:
id
description
submitter_id (foreign key to People table)
assigned_to_id (foreign key to People table)
etc

People table with columns:
id
name

models:
class Problem < ActiveRecord::Base
has_many :people

class Person < ActiveRecord::Base
has_many :problems

problem_Controller:
def list
@submitter = Person.find(params[:submitter_id] ???

views:problems:list.rhtml

<%= problem.submitter.name %> ???

Hi, Anthony,

maybe you want to try something along the lines of:

class Problem < ActiveRecord::Base
belongs_to :submitter, :class_name => ‘Person’, :foreign_key =>
‘submitter_id’
belongs_to :agent, :class_name => ‘Person’, :foreign_key =>
‘assigned_to_id’
end

(untested, but should do it)

Best Regards
Jan P.
