gii生成Goods放在common\models下。 增加

 public function actionIndex() { $user= new Goods; $user->name ="cyg"; $user->save(); } } 

修改：

 public function actionIndex() { $user = Goods::find()->where(['id'=>6])->one(); //获取name等于test的模型 $user->name = "liwen"; //修改age属性值 $user->save(); //保存 } } 

删除：

 public function actionIndex() { $user = Goods::find()->where(['id'=>6])->one(); $user->delete(); } }
