我是yii框架中的新手。我有3个表A，表B，表C.表A和表B都与主键和外键有关。方式表B和表C是用priamary和外键关系连接的。我想要显示，过滤管理页面的cgridview中的数据..使用yii fra 更新： 我有3个models.subscriber.php，assignment.php，groups.php 我想显示3个模型的属性，并在subscriber.php ???
的cgridview中显示它们subscriber.php ..........

当前的cgrid视图正在访问来自两个模型（assignemnt和订阅者）但不来自组的数据。并且它提供错误以获取非对象的属性
C：\ wamp \ www \ yii \ framework \ base \ CComponent.php（607）：eval（）'d code（1） ..那么plz检查这个2然后3个型号？需要紧急帮助。谢谢
答案 0 :(得分：2)
从表A的管理视图中，您应该能够通过在列定义中列出这些值来访问其他值：
'columns'=>array(
array('name'=>'column heading 1','value'=>'$data->modelB_nameinA->col_name1'),
array('name'=>'column heading 2','value'=>'$data->modelB_nameinA->C->col_name2'),
要对这些值进行过滤，您需要能够在modelA-＆gt; search（）函数中访问它们。我发现这样做的最简单方法是在A中为要从B和C显示的每个col_name显式设置一个公共值。您还需要将它们包含在modelA-＆gt; rules（）中的安全搜索语句中，并且为简单起见，也在modelA-＆gt; attributeLabels（）中。您可能还必须在A的关系中包含C，因此modelA类看起来像这样：
class A extends CActiveRecord
{
/**
* @return array validation rules for model attributes.
*/
public function rules()
{
// NOTE: you should only define rules for those attributes that
// will receive user inputs.
return array(
...
// Please remove those attributes that should not be searched.
array('Col1_fromA, Col2_fromA, Col1_fromB, Col1_fromC', 'safe', 'on'=>'search'),
);
}
/**
* Put here the names of the columns from B and C that you are wanting to filter on
*/
public $Col1_fromB;
public $Col1_fromC;
/**
* @return array relational rules.
*/
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(
'modelB_nameinA' => array(self::HAS_MANY, 'B', 'B_id'),
'modelC_nameinA' => array(self::HAS_MANY, 'C', array('C_id'=>'id'),'through'=>'B'),
);
}
/**
* @return array customized attribute labels (name=>label)
*/
public function attributeLabels()
{
return array(
'Col1_fromA' => 'Fancy name for Col1_fromA',
'Col2_fromA' => 'Fancy name for Col2_fromA',
'Col1_fromB' => 'Fancy name for Col1_fromB',
'Col1_fromC' => 'Fancy name for Col1_fromC',
);
}
/**
* Retrieves a list of models based on the current search/filter conditions.
* @return CActiveDataProvider the data provider that can return the models based on the search/filter conditions.
*/
public function search()
{
// Warning: Please modify the following code to remove attributes that
// should not be searched.
$criteria=new CDbCriteria;
// this is so those two tables are included in the SQL generated:
$criteria->with = array( 'B', 'C' );
$criteria->together=true;
$criteria->compare('Col1_fromA',$this->Col1_fromA,true);
$criteria->compare('Col2_fromA',$this->Col2_fromA,true);
$criteria->compare('modelB_nameinA.Col1', $this->Col1_fromB,true);
$criteria->compare('modelC_nameinA.Col1', $this->Col1_fromC,true);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
...
这样做的一个优点是您现在可以使用Col1_fromB和Col1_fromC作为cgridview中列定义中的名称值，您将获得在modelA定义中输入的花哨名称作为列标题。
答案 1 :(得分：0)
您需要在表A和B中定义关系以从表A中获取模型C. 表A关系：
public function relations() {
return array(
'tableB'=>array(self::HAS_ONE, 'TableB', 'tablea_id'),
);
}
表B关系：
public function relations() {
return array(
'tableC'=>array(self::HAS_ONE, 'TableC', 'tableb_id'),
);
}
因此，您可以访问与tableA相关的tableB和tableC模型：
$modelB = $tableA->tableB;
$modelC = $tableA->tableB->tableC;
您可以阅读有关关系活动记录的here。
在您的控制器操作中获取模型：
public function actionGrid() {
$model = new ModelA('search');
$model->unsetAttributes();
$this->render('view', array('model'=>$model));
}
使用CGridView查看代码：
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'grid',
'dataProvider'=>$model->search(),
'filter' => $model,
'ajaxUpdate'=>false,
'selectableRows'=>'10',
'columns'=>array(
array(
'id'=>'checkBoxId',
'class'=>'CCheckBoxColumn',
),
array(
'class'=>'CDataColumn',
'name'=>'modelA_attrib1',
'value'=>'$data->attrib1',
'sortable'=>true,
'filter'=>true,
),
array(
'class'=>'CDataColumn',
'name'=>'modelB_attrib1',
'value'=>'$data->modelB->attrib1',
'sortable'=>true,
'filter'=>true,
),
array(
'class'=>'CDataColumn',
'name'=>'modelC_attrib1',
'value'=>'$data->modelB->modelC->attrib1',
'sortable'=>true,
'filter'=>true,
),
...
<强>更新
如果我理解正确，您的users_phone_numbers和client_groups表中会有MANY_TO_MANY关系（组可能与许多电话号码相关，而号码则指向多个组）。
因此phone_number_group_assignment（通常称为phone_number_group）必须包含两个主键：
* @property integer $phone_number_id
* @property integer $group_id
subscriber的关系：
public function relations()
{
return array(
'groups' => array(self::MANY_MANY, 'Groups', 'phone_number_group_assignment(phone_number_id, group_id)'),
);
}
groups的关系：
public function relations()
{
return array(
'phone_numbers' => array(self::MANY_MANY, 'Subscriber', 'phone_number_group_assignment(group_id, phone_number_id)'),
);
}
因此，您可以从订阅者访问群组：$subscriber->groups
答案 2 :(得分：0)
在数据库中创建一个视图，并在连接操作后放置所有需要的列，然后创建模型。 我总是用这个
答案 3 :(得分：0)
正如@ user181452所说，创建一个View然后生成一个模型。其他方式是在目标模型中，将每个新属性与模型中的公共变量绑定
class NewModel {
public $new_attribute;
}
然后您就可以从视图中访问它了。你必须为你的项目选择最干净的方式，因为如果你有一个复杂的JOIN，创建一个视图会更好。
