How to publish pages via Model Admin in SilverStripe 4?

Question

I have created the Page, Data Object and Model Admin given below.

Page

class MyPage extends Page {

  private static $db = [];
  private static $singular_name = "My Page";
  private static $plural_name = "My Pages";
  private static $description = 'A page created for testing';
}

Data Object

use SilverStripe\ORM\DataObject;

class MyDataObject extends DataObject {

  private static $db = [
    'Test' => 'Int'
  ];
}

Model Admin

<?php

use SilverStripe\Admin\ModelAdmin;

class MyAdmin extends ModelAdmin  {

    private static $managed_models = [
        'MyPage',
        'MyDataObject'
    ];

    private static $url_segment = 'my-pages';
    private static $menu_title = 'My Page Admin';
}

When I create a new "MyDataObject" it creates and publishes the object when I click the save button. But when I create a "MyPage" it is still a draft after clicking the save button. I have to open the page from Pages Tree and hit the Publish button to publish the page.

You have to change your page's code as shown below. (Just add this line - private static $versioned_gridfield_extensions = true; )

<?php

class MyPage extends Page {

  private static $versioned_gridfield_extensions = true;

  private static $db = [];
  private static $singular_name = "My Page";
  private static $plural_name = "My Pages";
  private static $description = 'A page created for testing';

}
