ruby-on-rails - uuid_it ：无法批量分配受保护的属性：uuid

Question

我使用uuid_id gem 为我的应用程序中的各种模型生成 UUID（Rails 3.2.5 和 Ruby 1.9.3p194）。我正确地遵循了这里给出的步骤

创建标记为 的模型时出现此错误uuid_it。如果我uuid_it从模型中删除呼叫，它工作正常

这是日志的快照

ActiveModel::MassAssignmentSecurity::Error (Can't mass-assign protected attributes: uuid):

第 13 行在哪里application.create

编辑

应用程序/控制器/应用程序.rb

class ApplicationsController < ApplicationController
  # some code here
  def create
    @application = Application.new(params[:application])
    @application.creator = current_user
    @application.organization = current_organization
    if @application.save
      redirect_to @application, notice: "Successfully created application."
    else
      render action: 'new'
    end
  end
  # few lines here
