yii CGridView filter with relations

问题:

I'm using yii for my web application. In one of my view I have CGridView and dataprovider is Mail model. In this model I have relation with with 3 other models. In the grid I show cols from three models. How can I filter the CGridView?

回答1:

I have Restaurant, City, Country and User models with relations between them.

Model:

public function search() {
  $criteria=new CDbCriteria;
  $criteria->together = true;
  $criteria->with= array('xCountry','xCity','User');
  $criteria->compare('Id',$this->Id,true);
  $criteria->compare('Restaurant.Name',$this->Name,true);
  $criteria->addSearchCondition('xCountry.Name',$this->Country);
  $criteria->addSearchCondition('xCity.Name',$this->City);
  $criteria->compare('Zip',$this->Zip,true);
  $criteria->compare('Address',$this->Address,true);
  $criteria->compare('Description',$this->Description,true);
  $criteria->compare('Restaurant.Active',$this->Active,true);
  $criteria->addSearchCondition('User.Username',$this->Owner);
  $criteria->compare('Lat',$this->Lat);
  $criteria->compare('Lon',$this->Lon);

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

View:

$this->widget('zii.widgets.grid.CGridView', array(
      'id'=>'restaurant-grid',
      'dataProvider'=>$model->search(),
      'filter'=>$model,
      'columns'=>array(
        'Id',
        'Name',
        'Zip',
        'Address',
        'Active',
        array(
          'name' => 'User.Username',
          'header' => 'Username',
          'filter' => CHtml::activeTextField($model, 'Owner'),
          'value' => '$data->User->Username',
            ),
        array(
          'name' => 'xCountry.Name',
          'header' => 'Country',
          'filter' => CHtml::activeTextField($model, 'Country'),
          'value' => '$data->xCountry->Name',
            ),
        array(
          'name' => 'xCity.Name',
          'header' => 'City',
          'filter' => CHtml::activeTextField($model, 'City'),
          'value' => '$data->xCity->Name',
            ),
        array(
        'class'=>'CButtonColumn',
        ),
      ),
    ));

I hope this can help you.

UPDATE:

What if you try something like this:

...
'columns'=>array(
  'mailTemplate.name',
  'sendDate',
  'mailTemplate.subject',
  'client.email',
  ...

UPDATE #2:

Prepare yourself this will be a bit dirty.

Let's say we've got two classes, A and B. B belongs to A. B's got a property, let's say "color" and we want to display it in our grid where we list the "A"s.

The first thing you have to do is, manually create a property to your data provider class (what is "A"). This property will be "colorOfB", so you have to add "public $colorOfB;" to your model A.

Add criteria for this property:

$criteria->compare('B.color',$this->colorOfB,true);

Add the column to the grid:

array(
  'name' => 'B.color',
  'header' => 'Color of B',
  'filter' => CHtml::activeTextField($model, 'colorOfB'),
  'value' => '$data->B->color'),

The final thing is to set this property manually in A's controller:

$modelA = new A('search');
$modelA->colorOfB = $_GET['A']['colorOfB'];

this will set select list
