Ruby on Rails 3 - 回调不再起作用

大家好。

我有一个大问题。直到两周前，我的代码工作正常，但今天我意识到一些回调不再工作。

回调如下：

class DetailPurchase < ActiveRecord::Base
  belongs_to :purchase, :foreign_key => 'purchase_id'
  belongs_to :product, :foreign_key => 'product_id'
  belongs_to :buy_order_detail, :foreign_key => 'buy_detail_id'

  def before_create
    Storage.create!(:product_id => self.product_id, :current_quantity => self.quantity, :stg_data => purchase.prc_data)
  end

end

其想法是，每次创建 Detail_purhase 时，都应自动创建具有相同产品的存储。

但现在它不起作用，唯一的变化是现在我使用 jquery 而不是 prototype

这可能是问题所在吗？

Hi people.

I have a big problem. Untill 2 weeks ago, my code was working fine, but today I realize that some callbacks are not working any more.

The callback is the following:

class DetailPurchase < ActiveRecord::Base
  belongs_to :purchase, :foreign_key => 'purchase_id'
  belongs_to :product, :foreign_key => 'product_id'
  belongs_to :buy_order_detail, :foreign_key => 'buy_detail_id'

  def before_create
    Storage.create!(:product_id => self.product_id, :current_quantity => self.quantity, :stg_data => purchase.prc_data)
  end

end

The idea is that everytime a Detail_purhase is created, a storage with the same product should be created automatically after that.

But now it is not working, the only change is now I'm using jquery instead of prototype

Could that be the problem?

奇怪的是它起作用了。正确的语法是：

class DetailPurchase < ActiveRecord::Base
  belongs_to :purchase, :foreign_key => 'purchase_id'
  belongs_to :product, :foreign_key => 'product_id'
  belongs_to :buy_order_detail, :foreign_key => 'buy_detail_id'
  before_create :create_storage 

  def create_storage
    Storage.create!(:product_id => self.product_id, :current_quantity => self.quantity, :stg_data => purchase.prc_data)
  end
end

Weird it worked. Correct syntax is:

class DetailPurchase < ActiveRecord::Base
  belongs_to :purchase, :foreign_key => 'purchase_id'
  belongs_to :product, :foreign_key => 'product_id'
  belongs_to :buy_order_detail, :foreign_key => 'buy_detail_id'
  before_create :create_storage 

  def create_storage
    Storage.create!(:product_id => self.product_id, :current_quantity => self.quantity, :stg_data => purchase.prc_data)
  end
end
