安装:ruby script\plugin install acts_as_nested_set

Api

• root?() – 是否是根对象
• child?() – 是否是子对象(拥有父对象)
• unknown?() – 不知道该对象的状态(既不是根对象，也不是子对象)
• add_child(child_object) – 为根对象添加一个子对象(如果child_object是一个根对象的话，则添加失败)
• children_count() – 根对象的所有子对象的个数
• full_set() – 重新找到所有对象
• all_children() – 根对象的所有子对象
• direct_children() –根对象的直接子对象

建立一个rails project，名字叫"test",数据库采用mysql

rails  test -d mysql

mysql设置了密码，必须设置下数据库的访问密码

vim config/database.yml 

运行rake db:create 创建development环境的数据库

创建model

script/generate model XXX

增加一列

script/generate  migration add_columnname_to_XXX  columnname :type

增加测试数据

script/generate migration add_test_data

vim db/migrate/20091019012237_add_test_data.rb
 

def self.up
  3     Product.delete_all
  4     Product.create(:title => "PVC",
  5                    :description => %Q{
  6                    <p>
  7                    This is book
  8                    </p>
  9                    },
 10                    :price => 11,
 11                    :image_url => 'imgaes/svn.jpg')
 12   end
 13
 14   def self.down
 15     Product.delete_all
 16   end
 

添加后台管理页

script/generate model test

script/generate controller admin/test

vim congi/routes.rb

map.namespace :admin do |admin|

    admin.resources :tests

end
