I’ve got a table in my schema which doesn’t have an ID column. Here’s
the
migration -
==== START OF CUT OF MIGRATION ==========================
class CreateCountries < ActiveRecord::Migration
def self.up
create_table(:countries, :id => false, :options => ’ IN SFPS001’) do
|t|
# t.column :name, :string
t.column :country_code, :string, :null => false, :limit => 2
t.column :country_name, :string, :null => false, :limit => 50
end
end
def self.down
drop_table :countries
end
end
==== END OF CUT OF MIGRATION ============================
Here’s the model definition -
==== START OF CUT OF MODEL ==============================
class Country < ActiveRecord::Base
set_primary_key :country_code
has_many :trip_leg_passengers, :as => :country_passport
has_many :airports
validates_presence_of :country_code, :country_name
validates_uniqueness_of :country_code
validates_uniqueness_of :country_name
end
==== END OF CUT OF MODEL ================================
Using the formats in the usual RoR book from Prag Progs, I’ve got the
list,
show and edit functionality working. However the “Add” function is not
working giving the following error dump -
==== START OF CUT OF ERROR OUTPUT ========================

I am assuming I have to change something because the primary key is
COUNTRY_CODE and there isn’t an ID column. But I can’t work out what.
Any help appreciated.
