Updating the code formatting for better viewing.

伙计，

我已经看过一段时间了，但是我不明白这里可能发生什么.我正在使用Devise.

I have been looking at this for sometime but I don't understand what could be messing up here. I am using Devise.

class User < ActiveRecord::Base
  has_many :addresses
  accepts_nested_attributes_for :addresses

  # Other stuff here
end

class Address < ActiveRecord::Base

  belongs_to :user

  validates_presence_of :zip #:street_address1, 

结束

已发布的数据中存在zip，并且已发布的数据似乎格式正确.在网页表单上，我收到地址压缩不能为空"的错误消息.我一直在寻找导致无法批量分配受保护的属性"警告的原因，但没有发现任何对我有帮助的东西.

The zip is present in the data posted and the posted data seems to be formatted properly. On the web page form I am getting the error that "Addresses zip can't be blank". I have dug around for what causes the "Can't mass-assign protected attributes" warning but haven't found anything that will help me.

感谢您的想法和指导.

在用户模型中具有accepts_nested_attributes_for可使您将数据发送到地址模型.

Having accepts_nested_attributes_forin User model enables you to send the data to the Address model.

然后，在地址"模型中，您必须设置请求的attr_accessible

Then, in the Address model, you have to set the requested attr_accessible
