Ruby on rails RubyOnRails3中的单一模型不同视图和CRUD功能

ruby-on-rails ruby ruby-on-rails-3

Ruby on rails RubyOnRails3中的单一模型不同视图和CRUD功能,ruby-on-rails,ruby,ruby-on-rails-3,Ruby On Rails,Ruby,Ruby On Rails 3,作为RubyonRails的新手，我偶然发现了我应用程序的一部分。我阅读了RoR框架的基础知识，了解rails MVC的“约定优先于配置”特性。我有两个表，一个是apps\u events，另一个是apps\u events\u attributes。第一个的id是第二个的外键，在中有许多关系。app_events表有一个外键属性“app_id”字段，因此在特定app上选择I将重定向到其事件和属性。还有一个名为“is_standard”的字段，它实际上区分事件类型是标准事件还是自定义事件 现在，

作为RubyonRails的新手，我偶然发现了我应用程序的一部分。我阅读了RoR框架的基础知识，了解rails MVC的“约定优先于配置”特性。我有两个表，一个是apps\u events，另一个是apps\u events\u attributes。第一个的id是第二个的外键，在中有许多关系。app_events表有一个外键属性“app_id”字段，因此在特定app上选择I将重定向到其事件和属性。还有一个名为“is_standard”的字段，它实际上区分事件类型是标准事件还是自定义事件

现在，我必须在视图层上的两个不同选项卡中渲染特定应用程序的事件及其属性，并使用嵌套的表单作为其属性。用户可以通过此选项卡单击切换到标准和自定义事件。有谁能建议我如何实现相同的目标，并向我展示此场景的理想流程（模型名称和“is_standard”的检查部分，在控制器中传播相同的内容并渲染到视图）

顺便问一下，我可以在同一个模型上使用不同的控制器吗？如果我使用相同的控制器，那么它能够为不同的事件及其属性执行相同的CRUD功能吗？

我已经单独完成了所有的工作，并且这不是我最初认为的很难，所有的技巧都是由JQuery完成的。。。如果有人和我有同样的问题，我会和你分享这个想法

我的型号是

class AppsEvent < ActiveRecord::Base
  belongs_to :app
  has_many :apps_events_attributes, :foreign_key => 'apps_event_id',
       :class_name => 'AppsEventsAttribute',
       :dependent => :destroy
  accepts_nested_attributes_for :apps_events_attributes,
                            :reject_if => lambda { |a| (a[:name].blank? &&    a[:description].blank?) },
                            :allow_destroy => true
  validates_presence_of :description
  validates_presence_of :name
  validates_presence_of :code
  validates_presence_of :apps_events_attributes, :message => "can't be empty"
end  

class-AppsEvent“apps\u event\u id”，
：class_name=>“AppsEventsAttribute”，
：dependent=>：destroy
接受应用程序、事件和属性的嵌套属性，
：reject_if=>lambda{a |（a[：name].blank？&&a[：description].blank？}，
：allow_destroy=>true
验证是否存在：说明
验证是否存在：name
验证是否存在：代码
验证是否存在：应用程序\u事件\u属性，：message=>“不能为空”
