Hello, Rookie here ... learning rails and enjoying it ... having a
bit-o-trouble with has many in the following scenario:

class Party < ActiveRecord::Base
has_many :target_associations, :foreign_key => 'source_party_id',
:class_name => 'PartyAssociation',
:dependent => :destroy

has_many :source_associations, :foreign_key => 'target_party_id',
:class_name => 'PartyAssociation',
:dependent => :destroy
end

class PartyAssociation < ActiveRecord::Base
belongs_to :party, :foreign_key => "source_party_id"
belongs_to :party, :foreign_key => "target_party_id"
end

class CreateParties < ActiveRecord::Migration
def change
create_table :parties do |t|
t.timestamps
end
end
end

class CreatePartyAssociations < ActiveRecord::Migration
def change
create_table :party_associations, :id => false do |t|
You should not have :id false, the table needs an id column. It is
generally only when you use has_and_belongs_to_many that you do not
require an id column

Colin
t.integer :source_party_id
t.integer :target_party_id

t.timestamps
end
end
end

This RSpec statement:
it "should destroy source associations" do
@party.destroy
end

Causes this ERROR MESSAGE:
ActiveRecord::StatementInvalid: SQLite3::SQLException: no such column:
party_associations.: DELETE FROM "party_associations" WHERE
"party_associations"."" = ?

What am I doing wrong that prevents active record from knowing how to
form the delete statement?
