Skmvc is an elegant, powerful and lightweight MVC web framework built using kotlin. It aims to be swift, secure, and small. It will turn java's heavy development into kotlin's simple pleasure.
Inspired by 2 php frameworks: kohana
cp example.htaccess .htaccess
Controller handles request, and render data to response.
It has property req to represent request, res to represent response.
In application/classes/Controller directory, you should create your own controller class:
/**
* application/classes/Controller/Home.php
*/
class Controller_Home extends Controller
{
public function action_index()
{
$this->res->body("hello world");
}
}
visit http://localhost/skmvc/
public function action_view()
{
// 创建视图
$view = new View('test', array('name' => 'shi')); // 自定义视图, 视图文件 application/views/test.php
// $view = $this->view(array('name' => 'shi')); // 默认视图, 视图文件 application/views/$controller/$action.php
// 设置变量
$view->set('age', 24);
// 渲染
// $this->res->body($view->render()); // 显示渲染视图: 调用view::render()
$this->res->body($view); // 隐式渲染视图
}
vim application/views/test.php
<?php
echo "hello $name, your age is: $age";
visit http://localhost/skmvc/welcome/view
Orm provides object-oriented way to mainpulate db data.
It has 2 concepts:
1 Orm meta data: include information as follows
1.1 mapping from object to table
1.2 mapping from object's property to table's column
1.3 mapping from object's property to other object
2 Orm object | Model
2.1 visit property
you can use operator -> to visit orm object's property.
2.2 method
query_builder() return a query builder to query data from table
create() create data
update() update data
delete() delete data
user table
CREATE TABLE `user` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(255) NOT NULL,
`age` smallint(3) unsigned NOT NULL DEFAULT '0',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='用户表';
contact table
CREATE TABLE `contact` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`user_id` int(11) unsigned NOT NULL,
`email` varchar(254) NOT NULL,
`address` varchar(500) NOT NULL DEFAULT '',
PRIMARY KEY (`id`),
KEY `uniq_user` (`user_id`)

Odm provides object-oriented way to mainpulate mongodb data.
It has 2 concepts:
1 Odm meta data: include information as follows
1.1 mapping from object to collection
1.2 mapping from object's property to collection's column
1.3 mapping from object's property to other object
2 Odm object | Model
2.1 visit property
you can use operator -> to visit orm object's property.
2.2 method
query_builder() return a query builder to query data from table
create() create data
update() update data
delete() delete data
Mongodb doesnot need to create collections in advance.
Just use it, it will be created automatically.
Create models just like Orm.
Use models just like Orm.
Thanks for the elegant encapsulation. Odm extends the same super class just like Orm. Odm just needs to override the following properties and methods:
$_primary_key: Mongodb's default primary key is_iddb():Mongooinstancequery_builder():Odm_Query_Builderinstance
/**
* ODM
* 实现：
* 重用ORM的代码，只是变动部分属性 $_primary_key / 方法 db()
* 重用关系型数据的概念，mongo的collection对应db的table
*
* 关系型数据库与mongodb的3个层次的兼容：
* 1 Db层：Db 与 Mongoo 不用兼容
* 2 Query_Builder层：Db_Query_Builder 与 Mongoo_Query_Builder 尽量兼容
* 3 ORM层：ORM 与 ODM 完全兼容，终极目标
