Yii cgridview using dynamic active record model - yii

Question

I'm using the Yii-dynamic-active-record model class to get and put data to various database tables. Now I'd like to use cgridview to quickly build some views of this data, but I'm getting hung-up on writing a search function for this class.
I know that I could always do a foreach loop within the view and make my own html table, but if I could get the Yii way working that would be great for DRY.
*All the db tables have a ID column and this is the only column that really needs to be displayed... if you could get all the columns that would just be bonus points.
Thanks :)
Model
public function search()
{
$criteria=new CDbCriteria;
$criteria->compare('ID',$this->ID);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
View
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'entry-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
'ID',
),
));
Controller
$tablename=$_GET['tname'];
$table=Entry::forTable($tablename);
$model=$table->findAll();
if(isset($_GET['Entry']))
$model->attributes=$_GET['Entry'];
$this->render('all',array(
'model'=>$model,
));

I am a little confused by what you have done here, however I think I have a solution. First off, in line 3 of your controller code, you call $model = $table->findAll(); this is likely not what you intended, as it will provide you with an ActiveRecord[]. What you want to do is to pass your $table into the gridview. So your controller code would look like this:
$tablename=$_GET['tname'];
$model=Entry::forTable($tablename);
if(isset($_GET['Entry']))
$model->attributes=$_GET['Entry'];
$this->render('all',array(
'model'=>$model,
));
you then need to pass in the table name to the CActiveDataProvider in your model:
public function search()
{
$criteria=new CDbCriteria;
$criteria->compare('ID',$this->ID);
return new CActiveDataProvider($this->tableName(), array(
'criteria'=>$criteria,
));
}
now for the "yucky" part, you need to edit the static model method of CActiveRecord to this:
if(isset(self::$_models[$className]))
return self::$_models[$className];
else
{
if(class_exists($className)){
$model=self::$_models[$className]=new $className(null);
$model->_md=new CActiveRecordMetaData($model);
$model->attachBehaviors($model->behaviors());
}
else{
$model = Entry::forTable($className);
}
return $model;
}
This tells it to load from the Entry table when a class of that name does not exist. This practice is discouraged, however its the only way I see of getting around your issue.
