Change $summary_fields in a Page class

Questions
1

Silverstripe Version: 4.4

I’d like to change the fields used when viewing a page in a list.

By default they are Page Name Page type and Last Updated

I’ve tried both $summary_fields and $extra_summary_fields in my Page class.

I’ve done dev/build?flush=all with no change.

Found this here: https://docs.silverstripe.org/en/4/developer_guides/forms/field_types/gridfield/

use SilverStripe\Forms\GridField\GridField;
use SilverStripe\CMS\Model\SiteTree;

class Page extends SiteTree 
{
    
    public function getCMSFields() 
    {
        $fields = parent::getCMSFields();

        $fields->addFieldToTab('Root.Pages', 
            $grid = new GridField('Pages', 'All pages', SiteTree::get())
        );

        // GridField configuration
        $config = $grid->getConfig();

        //
        // Modification of existing components can be done by fetching that component.
        // Consult the API documentation for each component to determine the configuration
        // you can do.
        //
        $dataColumns = $config->getComponentByType(GridFieldDataColumns::class);
        
        $dataColumns->setDisplayFields([
            'Title' => 'Title',
            'Link'=> 'URL',
            'LastEdited' => 'Changed'
        ]);

        return $fields;
    }
}

Interesting.

A bit more info I should have added. I’m not trying to do it for all pages. I have a holder page (NewsListPage) and a view page (NewsPage).

I’d like to change the columns for those NewsPage pages only. The only $allowed_children Pages under NewsListPage are the NewsPage types.

I’ve used getCMSFields in both types to set their editing forms.

I’ve put some debugging in both page classes getCMSFields functions and doesn’t seem to get hit. I also added some debugging to SiteTree::getCMSFields and still nothing.

This is the view I’m trying to change:

Digging in the code these fields are hard coded in the CMSMain::ListViewForm Controller.
