I am not sure what goes wrong exactly. I have 4 other tables in my database and this is the only one that it wont work and it gives an error.
Can you maybe explain to me what goes wrong?? is the problem from my database??
Later on it adds the record to the database even if it give an error before.

Answer 1

CGridView displays a list of data items in terms of a table.
Exception because CGidView not have property 'data'. Class have property 'dataProvider'. Here is an easy example of CGridView. You can use GII for generation examples from your models.
// in your view.
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'document',
// you can't use key 'data' here
'dataProvider' => $document->search(), // #var Document $document - your model
'columns' => array(
'id',
// ... other properties
)
));
// in model Document
public function search()
{
$criteria = new CDbCriteria();
$criteria->compare('id',$this->id);
//$criteria->compare('one_more_poperty', $this->one_more_poperty);
...
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
