软件简介

ActiveRecord.js 是一个开源的JavaScript 对象映射框架，包括：

• Google Gears (client-side persistence)
• In Memory (if no SQL server is available on the client)
• Adobe AIR (client-side persistence)
• SQLite and MySQL (via Aptana Jaxer, the open source Ajax server)
• additional environments (like HTML5) expected to come through working with the community on the project

ActiveRecord.js abstracts away underlying SQL commands so that JavaScript
developers can have a unified API for storing, finding, selecting and
retrieving objects and their data using the ActiveRecord pattern popularized
by the Ruby on Rails community.

示例代码：

1. var User = ActiveRecord.define(‘users’,{
2. username: ‘’,
3. email: ‘’
4. });
5. User.hasMany(‘articles’);
6. 1. var ryan = User.create({
7. username: ‘ryan’,
8. email: 'rjohnson@aptana.com‘
9. });
10. 1. var Article = ActiveRecord.define(‘articles’,{
11. name: ‘’,
12. body: ‘’,
13. user_id: 0
14. });
15. Article.belongsTo(‘user’);
16. 1. var a = Article.create({
17. name: ‘Announcing ActiveRecord.js’,
18. user_id: ryan.id
19. });
20. a.set(‘name’,’Announcing ActiveRecord.js!!!’);
21. a.save();
22. 1. a.getUser() == ryan;
23. ryan.getArticleList()[0] == a;
