I have set up the following relationships Rails 2.3.5 and on update I
am finding that orphaned records are generated. Are my relationships
wrong or is there a recommended way to manage these orphaned records
on an update. Code is detailed below:
class User
has_many :management_assignments, :foreign_key => :manager_id
has_many :listings, :through => :management_assignments
....
class ManagementAssignment < ActiveRecord::Base
attr_accessible :manager_id, :id, :listing_id, :assignor_id, :status,
:assignment_date, :completed_date
belongs_to :manager, :class_name => 'User'
belongs_to :assignor, :class_name => 'User'
belongs_to :listing
class Listing
has_one :management_assignment, :dependent
=> :destroy
has_many :managers, :through => :management_assignments, :source
=> :user
accepts_nested_attributes_for :management_assignment, :allow_destroy
=> true
My update controller action is a bulk update which uses a nested form
to change the manager on the relationship as follows:
def update_multiple
@listings = Listing.find(params[:listing_ids])
@listings.each do |listing|
listing.last_updated_by = current_user
listing.update_attributes!(params[:listing].reject { |k,v|
v.blank? })
end
flash[:notice] = "Updated listings!"
redirect_to admin_listings_path
end
As a noob any help or feedback as to how to eliminate these orphaned
records would be much appreciated.
Thx.
David
