Question

当我点击提交时，参数会显示所有数据，但是，当我保存时，它显示为：

 SQL (1.0ms)  INSERT INTO `billings` (`birth`, `city`, `country`, `created_at`, `gender`, `ictype`, `idno`, `marital`, `name`, `national`, `phone`, `postcode`, `race`, `reference_id`, `shipping_address`, `state`, `street1`, `title`, `updated_at`, `uptime`, `user_id`) VALUES (NULL, NULL, NULL, '2014-08-28 02:55:19', NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, 0, NULL, NULL, NULL, '2014-08-28 02:55:19', NULL, 1)


class Billing < ActiveRecord::Base
#  attr_accessible :user_id
  attr_accessible :title, :birth, :ictype, :idno, :race, :gender, :national, :street1, :postcode, :city, :state, :marital, :shipping_address

  belongs_to :user
end

Class ShoppingCartsController < ApplicationController

    def create
        @billing = Billing.new(params[:billing])
        @billing = current_user.build_billing
        @billing.save
    end

end

为什么会这样？

Answer 1

答案是：

def create
#    @billing = Billing.new(params[:billing])
    @billing = current_user.build_billing(params[:billing])
    @billing.save
end

创建操作时数据库中的NULL值
