rails-activerecord-model-rails-lab-v-000-源码
ActiveRecord模型Rails实验室
目标
手动创建迁移
手动创建模型
建立模型实例方法
建立模型
您可以在spec/models目录中找到此应用程序的测试套件，并使用以下命令运行它们： bundle exec rspec 。 该实验室进行测试以确保您的应用程序可以创建记录，并且具有可以在模型上调用的实例方法。
指示
手动创建一个名为“ students的表，该表具有以下列： first_name和last_name –这应该通过创建新的数据库迁移来完成
为学生表创建一个模型，该模型继承自ActiveRecord :: Base
在模型中实现to_s实例方法，该方法将为学生返回串联的名字和姓氏。 例如： first_name: "Daenerys", last_name: "Targaryen" => "Daenerys Targaryen"
