How to show zend framework data grid data sorted by "date" as default?

Question

How to show zend framework data grid data sorted by "date" as default? When i get on the page, i wish to see data grid sorted by time as default, without getting params in URL like .../order/created_DESC/

$testimonials = new Application_Model_DbTable_Testimonials();
        $source = new Bvb_Grid_Source_Zend_Table($testimonials);

Thanks.

I solved this by passing to datagrid $select instead of $object

$testimonials = new Application_Model_DbTable_Testimonials();
        $source = new Bvb_Grid_Source_Zend_Table($testimonials);

is now

$testimonials = new Application_Model_DbTable_Testimonials();
        $testimonials->setSortOrder('created');
        $source = new Bvb_Grid_Source_Zend_Select($testimonials->getTestimonials());

Answer 1

It's hard to see what your class is doing since you didn't posted that one.

But when it's usess the fetchAll() function you can do two things:

Option 1

When there is an fetchAll()-call in the Grid class you can make this one:

$testimonialsTable->fetchAll(null, 'date'));

Option 2

You can re-write the fetchAll-Method in the Application_Model_DbTable_Testimonials class, when you make

public function fetchRow($where = null, $order = null, $offset = null)
{
    if ($order===null) : $order='date'; endif;

    return parent::fetchAll(where, $order, $offset)
}

Please notice in the last example fetchess always will be default sorted by the date-field.
