Lumberjack Sort and Summary

A common use case for SilverStripe's Lumberjack module is the holder/page pattern. In this case, the holder page will only have one type of child page.

Because Lumberjack is built flexible enought to accommodate multiple types of child pages, some features that we might expect when only a single page type is allowed are missing. Such as:

• Using the default sort order for the child page type
• Listing the pages with the defined summary fields
• Labeling the listings with the name of the name of the child type instead of "Child Pages"

This module applies the above when a single child type is defined for the parent holder page.

Thanks to @bcairns for the code and documentation this module was based on

Installation

composer require evanshunt/lumberjack-sort-and-summary

Usage

Define $allowed_children for the parent page. (Can be done either in yml config or model)

namespace MyNamespace;

use Page;

class StoryLandingPage extends Page
{
    private static $allowed_children = [
        StoryDetailsPage::class
    ];
}

Define $plural_name, $summary_fields, and $default_sort for child page.

namespace MyNamespace;

use Page;

class StoryDetailsPage extends Page
{
    private static $table_name = 'StoryDetails';
    private static $singular_name = 'Story';
    private static $plural_name = 'Stories';

    private static $can_be_root = false;
    private static $default_parent = StoryLandingPage::class;

    private static $db = [
        'PublicationDate' => 'Date',
    ];

    private static $summary_fields = [
        'Title',
        'PublicationDate'
    ];

    private static $default_sort = 'PublicationDate DESC';
}

Install and configure Lumberjack

MyNamespace\StoryDetailsPage:
  show_in_sitetree: false
MyNamespace\StoryLandingPage:
  extensions:
    - SilverStripe\Lumberjack\Model\Lumberjack

Configuration

No additional configuration is needed. This module overloads methods in Lumberjack itself, to check the value of $allowed_children on the parent class, and if only one class is defined, it will apply the changes based on the config values in the child class.
