5-関連モデル

1、 SectionModel.class.php
RelationModelを継承するには、モデルとクラス名をマッピングして、対応するデータテーブルとactionクラスを書きます.

 1 <?php

 2     class SectionModel extends RelationModel{

 3         public $_link=array(

 4             'Category'=>array(

 5                 'mapping_type'=>HAS_MANY,  //     1：n

 6                 'class_name'=>'Category',    //    

 7                 'foreign_key'=>'sectionid',     //  ，      

 8                 'mapping_name'=>'category',    //    

 9                 'mapping_order'=>'sectionid desc', //    

10             ),

11             'Article'=>array(

12                 'mapping_type'=>HAS_MANY,

13                 'class_name'=>'Article',

14                 'foreign_key'=>'sectionid',

15                 'mapping_name'=>'article',

16             

17             ),

18         );

19         

2、SectionAction.class.php  
関連付けrelation(true)をオンにします->

<?php

        class SectionAction extends CommonAction{

            public function index(){

                $sec=new SectionModel();

//Relation(true)     User           

//-----   

//dump($sec->relation(true)->find(3));
