Yii自定義CRUD。擴展不同表的公共模型

Question

我有20個表的項目。 所有表中的數據管理都是相同的。 只有表中的列將有所不同。 所以我想做出共同的模式，共同控制和共同的文件夾中的所有表 而在這之後僅延長所有這些類爲每個表

型號/ Crud.php

<?php 

class Crud extends CActiveRecord 
{ 
    public $crudTable = ''; 
    public $crudColumns = array(); 

    public static function model($className=__CLASS__) 
    { 
     return parent::model($className); 
    } 

    public function tableName() 
    { 
     return '{{'.$this->crudTable.'}}';   
    } 

    public function rules() 
    { 
     $rules = array(); 

     foreach ($this->crudColumns as $k=>$v) { 
      foreach ($v ['rules'] as $vv) { 
       $rules[] = array_merge(array($k), $vv);  
      } 
      if($v['search']) $rules[] = array_merge(array($k), array('safe', 'on'=>'search')); 
     } 

     return $rules; 
    } 

    public function relations() 
    { 
     return array(
     ); 
    } 

    public function attributeLabels() 
    { 
     $attributeLabels = array(); 

     foreach ($this->crudColumns as $k=>$v) 
     { 
      $attributeLabels[$k] = $v['attributeLabel']; 
     } 
     return $attributeLabels; 
    } 

    public function search() 
    { 
     $criteria=new CDbCriteria; 

     foreach ($this->crudColumns as $k=>$v) 
     { 
      if($v['search']) 
      { 
       $criteria->compare($k,$this->$k,(($v['search'] == 'partial') ? 'partial' : false));     
      } 
     } 

     return new CActiveDataProvider($this, array(
      'criteria'=>$criteria, 
     )); 
    } 
} 

車型/ Country.php

class Country extends Crud 
{ 
    public $crudTable = 'country'; 
    public $crudColumns = array( 
     'id' => array(
      'atributeLabel' =>'ID', 
      'rules' => array (
       array('numerical', 'integerOnly'=>true) 
      ), 
      'search'=>true, 
      'grid'=>true,     
      'view'=>true, 
      'form'=>true,     
     ), 
     'title' => array(
      'atributeLabel' =>'Title', 
      'rules' => array (
       array('required'), 
       array('length', 'max'=>128)          
      ), 
      'search'=>'partial', 
      'grid'=>true, 
      'view'=>true, 
      'form'=>true,            
     ),         
     'code' => array(
      'atributeLabel' =>'Code', 
      'rules' => array (
       array('required'), 
       array('length', 'max'=>2)          
      ), 
      'search'=>'partial', 
      'grid'=>true, 
      'view'=>true, 
      'form'=>true,            
     ),   
     'description' => array( 
      'atributeLabel' =>'Description', 
      'rules' => array (
       array('safe'), 
      ), 
      'search'=>'partial', 
      'view'=>true, 
      'form'=>true,        
     ),         
     'onoff' => array(
      'atributeLabel' =>'Onoff', 
      'rules' => array (
       array('numerical', 'integerOnly'=>true), 
      ), 
      'search'=>true, 
      'grid'=>true,     
      'view'=>true, 
      'form'=>true,        
     ) 
    ); 

    public static function model($className=__CLASS__) 
    { 
     return parent::model($className); 
    } 

    public function relations() 
    { 
     // NOTE: you may need to adjust the relation name and the related 
     // class name for the relations automatically generated below. 
     return array(
      'providers' => array(self::HAS_MANY, 'Provider', 'country_id'), 
     ); 
    } 
} 

組件/ CrudController.php

class CrudController extends CController 
{ 
    public $crudModel='';  
    public $crudModelString=''; 
    public $menu=array(); 
    public $breadcrumbs=array(); 

    public function filters() 
    { 
     return array(
      'accessControl', // perform access control for CRUD operations 
     ); 
    } 

    public function accessRules() 
     { 
     return array(
      array('allow', // allow all users to perform 'list' and 'show' actions 
       'actions'=>array('index', 'view'), 
       'users'=>array('*'), 
      ), 
      array('allow', // allow authenticated users to perform any action 
       'users'=>array('@'), 
      ), 
      array('deny', // deny all users 
       'users'=>array('*'), 
      ), 
     ); 
    } 

    public function actionIndex() 
    { 
     $model=new $this->crudModel('search'); 
     $model->unsetAttributes(); // clear any default values 
     if(isset($_GET[$this->crudModel])) 
      $model->attributes=$_GET[$this->crudModel]; 

     $this->render('/crud/index',array(
      'model'=>$model, 
     )); 
    }   

    public function actionView($id) 
    { 
     $this->render('/crud/view',array(
      'model'=>$this->loadModel($id), 
     )); 
    } 

... 
Some code 
... 

    public function loadModel($id) 
    { 
     $model=Crud::model()->findByPk($id); 
     if($model===null) 
      throw new CHttpException(404,'The requested page does not exist.'); 
     return $model; 
    } 

... 
Some code 
...} 

控制器/ CountryController.php

class CountryController extends CrudController 
{ 
    public $crudModel='Country'; 
    public $crudModelString='country';  
} 

它可以正常工作的指標作用，但R =國家/視圖& ID = 278送我錯誤

The table "Crud" for active record class "Crud" cannot be found in the database.

如何將表名稱發送到靜態方法並使此代碼正常工作？

Answer 1

更改loadModel這樣的：

public function loadModel($id) 
{ 
    $model=Crud::model($this->crudModel)->findByPk($id); 
    if($model===null) 
     throw new CHttpException(404,'The requested page does not exist.'); 
    return $model; 
} 

這將加載相應的表的模型。
