关于模型部分參考http://blog.csdn.net/buyingfei8888/article/details/40208729
控制器部分：
<?php
class GoodsController extends Controller{
function actionShow(){
$goods_model = Goods::model(); //简单查询能够通过模型里面静态方法来创建
$sql = "select goods_id,goods_name,goods_price,goods_create_time from {{goods}} limit 10";
$goods_infos = $goods_model ->findAllBySql($sql);//通过原生态sql进行查询。findALlBySql返回一个对象数组，
// var_dump($goods_infos);
// foreach($goods_infos as $v){
// echo $v ->goods_name ."<br />";
// }
// exit();
$this->render('show',array("goods_infos"=>$goods_infos)); //这样的方式会渲染布局
//$this->renderPartial('add',array('goods_model' => $goods_model)); //这样的方式不会渲染布局
}
function actionAdd(){
$goods_model = new Goods();
if(isset($_POST['Goods'])){
// $goods_model->goods_name = 'apple phone';
// $goods_model->goods_price = '5199';
// $goods_model->goods_weight=102;
//对上面代码优化
foreach($_POST['Goods'] as $_k => $_v){
$goods_model -> $_k = $_v;
}
}
if($goods_model->save()){
$this ->redirect('./index.php?r=houtai/goods/show');
}else{
echo "error";
}
// $this->renderPartial('add',array('goods_model' => $goods_model));
}
/*
* YII 对get优化，作为參数传递进来
* 模板和加入时模板基本一样。直接复制略微改动即可。都是通过小物件 ，自己主动会把数据关联起来，节省开发成本
*/
function actionUpdate($id){
//除了加入数据进行 new Goods()。 别的都是调用静态方法 调用save方法运行是insert
// Goods：：model（）调用save方法运行是update
$goods_model = Goods::model();
$goods_info = $goods_model ->findByPk($id); //$goods_info 是 数据模型对象
if(isset($_POST['Goods'])){
foreach($_POST['Goods'] as $_k => $_v){
$goods_info -> $_k = $_v;
}
if($goods_info -> save()){
$this ->redirect('./index.php?r=houtai/goods/show');
}
}
$this->renderPartial('update',array('goods_model' => $goods_info ));
}
function actionDel($id){
//依据$id获得被删除数据对象。通过该对象调用delete方法就ok
$goods_mode = Goods::model();
$goods_info = $goods_mode ->findByPk($id); //获得被删除商品模型对象
if($goods_info ->delete() ){
$this ->redirect('./index.php?r=houtai/goods/show');
}else{
echo 'error';
}
}
function actionJia(){
$goods_model = new Goods();
// $goods_model=Goods::model();
$goods_model->goods_name = 'apple phone';
$goods_model->goods_price = '5199';
$goods_model->goods_weight=102;
var_dump($goods_model->save());
// var_dump($goods_model);
if($goods_model->save()){
echo 'success';
}else{
echo "error";
}
}
}

关于为什么Goods：：model()和new Goods() 运行save方法会分别调用update 和insert方法能够看CActiveRecord 源代码。
