after_create callback is not called in an association

#5800

I have the following scenario:

class A < AR::Base
  has_many :items, class_name => 'B'
end

class B < AR::Base
  belongs_to :a

  after_create :update_x

  private

  def update_x
    self.x.att += self.another_att
  end
end

When I call B.create the after_create callback is called. But when I call A.items.create the callback is not called.

I'm using Rails 3.0

This is working fine for me -- the callback is getting called in both cases.

I tried it again in a new Rails 3 application and I have the same behavior.

class Order < ActiveRecord::Base
  has_many :items, :class_name => 'OrderItem'
end

class OrderItem < ActiveRecord::Base
  belongs_to :order

  after_create :update_value

  private

  def update_value
    self.order.value += self.price
  end
  
end

In Rails console:

>> order
=> #<Order id: 1, value: nil, created_at: "2010-10-15 22:21:36", updated_at: "2010-10-15 22:21:36">
>> order.value = 0
>> order.save!
=> true
>> order.items.create(:price => 10)
=> #<OrderItem id: 1, price: 10, order_id: 1, created_at: "2010-10-15 22:22:54", updated_at: "2010-10-15 22:22:54">
>> order
=> #<Order id: 1, value: 0, created_at: "2010-10-15 22:21:36", updated_at: "2010-10-15 22:22:52">
>> order.items.create(:price => 10)
=> #<OrderItem id: 2, price: 10, order_id: 1, created_at: "2010-10-15 22:23:23", updated_at: "2010-10-15 22:23:23">
>> order
=> #<Order id: 1, value: 0, created_at: "2010-10-15 22:21:36", updated_at: "2010-10-15 22:22:52">
>> OrderItem.create!(:order => order, :price => 20)
=> #<OrderItem id: 3, price: 20, order_id: 1, created_at: "2010-10-15 22:23:48", updated_at: "2010-10-15 22:23:48">
>> order
=> #<Order id: 1, value: 20, created_at: "2010-10-15 22:21:36", updated_at: "2010-10-15 22:22:52">
