Question

这个错误令我感到困惑。这是控制器代码（不是Estimates控制器）

...

@estimate = Estimate.find_by_link(params[:link])

...

if @estimate.customer_id.nil?
  @estimate.update_attributes(customer: current_user)
end

它给了我以下错误：

SQL (13.0ms)  UPDATE "estimates" SET "customer_id" = 24, "updated_at" = '2014-07-28 21:59:26.193000' WHERE "estimates"."id" = 277
Completed 500 Internal Server Error in 436ms

ActiveModel::MissingAttributeError (can't write unknown attribute 'estimate_id'):
 app/controllers/quotes_controller.rb:60:in 'new'

然而这很好用：

if @estimate.customer_id.nil?
  Estimate.find_by_link(params[:link]).update(customer: current_user)
end

如果我使用.update而不是.update_attributes

，它会做同样的事情

我正在运行Rails 4.0.0和Postgres

增加型号：

class Estimate < ActiveRecord::Base

 date_time_attribute :due_date

 has_many :translation_jobs, :dependent => :destroy
 has_many :price_adjustments, as: :adjustable

  self.email.match(/\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i)
 end

 private

 end
end

 end
end

Rails .update失败 - id是未知属性？
