Folks,
各位，
I have been looking at this for sometime but I don't understand what could be messing up here. I am using Devise.
我一直在看这个，但我不明白这里有什么问题。我正在使用设计。
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,
end
结尾

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.
zip 存在于发布的数据中，并且发布的数据似乎格式正确。在网页表单上，我收到“地址 zip 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，但没有找到任何可以帮助我的东西。
Thanks for your thoughts and pointers.
感谢您的想法和指点。

Edit:
编辑：
Having accepts_nested_attributes_forin User model enables you to send the data to the Address model.
其accepts_nested_attributes_for在用户模式使您能够将数据发送到地址模型。
Then, in the Address model, you have to set the requested attr_accessible
然后，在 Address 模型中，您必须设置请求的 attr_accessible

Inside of SpecificModel(appfolder/app/model/specific_model.rb)
内部SpecificModel（appfolder/app/model/specific_model.rb）
Try using
尝试使用
attr_accessible :addresses_attributes, :another_attribute_to_make_mass_assignable, :another_attribute, etc.
attr_accessible :addresses_attributes, :another_attribute_to_make_mass_assignable, :another_attribute, etc.

Just include the datafieldin the model as mentioned below
只需在模型中包含数据字段，如下所述
attr_accessible :addresses_attributes
