Bug in nested_attributes when the primary key is not "id"

Reported by Mathieu Arnold | April 14th, 2010 @ 04:48 PM

In 2ff5f38abb4a44ed5356c34b40d30d446fb63408 a bug was introduced on line 357, in the case the primary key is not called "id".

Example :

create_table 'customer' do |t|
  t.string :name
create_table 'invoice', :primary_key => 'id_invoice' do |t|
  t.integer :client_id
  t.string :number
class Customer < ActiveRecord::Base
  has_many :invoices
  accepts_nested_attributes_for :invoices
class Invoice < ActiveRecord::Base
  set_primary_key 'id_invoice'
  belongs_to :customer

> @customer = Customer.create
> @customer.invoices.create
> @customer.update_attributes({invoices_attributes => {"0" => {"id" => "1", "number" => "1523"}}})

will fail because the query generated will be :

SELECT invoices.* FROM invoices WHERE invoice.client_id = 1 AND IN ('1')

which is wrong, it should be invoice.id_invoice.

Changing line 357 to do


and not do a all(:conditions ...).
