The Rails API doc (api.rubyonrails.org) says that :autosave is still a
valid option for belongs_to in the latest version of Rails. However, a
look at the activerecord/lib/active_record/associations.rb (line 1590)
reveals that it is not in the @@valid_keys_for_belongs_to_association
array. I also noticed that it’s not in the ActiveRecord API doc
Does anyone have any more information on this? What is the current best
practice for persisting your child objects when saving a parent object?
Here’s an example:
class PaymentMethod < ActiveRecord::Base
belongs_to :billing_address, :class_name => “Address”
class Address < ActiveRecord::Base
class PaymentMethodsController < ActionController::Base
@pm = PaymentMethod.find(params[:id])
@pm.billing_address.line_one = params[:billing_address][:line_one]
Thanks in advance.
