I’m using a CGridView generated by Gii’s CRUD generator, and customized one of the columns to show a related model’s attribute.
What happened is that the ability to filter by that column is now gone. (In the example: Venue)
How can I specify a way to filter the column?
I’d prefer to build a <select> with possible options, but a string filter would be fine too.
// $model is an Event, which BELONGS_TO Venue.
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'event-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
'id',
'datetime',
'text',
'Venue.name', // <-- this one. originally was 'venue' I.E. Event's foreign key pointing to venues.
array(
'class'=>'CButtonColumn',
),
),
));
