Adding new panels

We can create custom panels to display anything that we like on our dashboard.

In this example we will create a panel that displays recently edited properties.

Creating a new panel

Say we have a custom DataObject named Property that is controlled through a custom ModelAdmin called PropertiesAdmin. We would like to add a panel that lists recently edited properties.

First we create a dashboard-custom folder in our root directory to house our custom dashboard code. To enable the dashboard-custom directory to be picked up by Silverstripe we must create a _config directory inside dashboard-custom.

Next we create a new PHP file RecentlyEditedPropertiesPanel.php in dashboard-custom/src/Panels/. In our dashboard-custom/src/Panels/RecentlyEditedPropertiesPanel.php file we create a RecentlyEditedPropertiesPanel class, which extends DashboardPanel:

<?php

use Plastyk\Dashboard\Model\DashboardPanel;
use SilverStripe\Security\Permission;

class RecentlyEditedPropertiesPanel extends DashboardPanel
{
    public function canView($member = null)
    {
        if (!Permission::checkMember($member, 'CMS_ACCESS_PropertiesAdmin') || !class_exists(Property::class) || ! parent::canView($member)) {
            return false;
        }

        return parent::canView($member);
    }

    public function getData()
    {
        $data = parent::getData();

        $data['Results'] = $this->getResults();

        return $data;
    }

    public function getResults()
    {
        return Property::get()->filter(['LastEdited:GreaterThan' => date('c', strtotime('-6 months'))])->sort('LastEdited DESC')->limit(8);
    }
}

In our RecentlyEditedPropertiesPanel class we have a canView, a getData and a Results function.

• canView checks if the current user is able to view this panel by checking if they have permission to view the Property data.
• getData fetches the results for the template.
• Results returns a list of properties that have been edited in the last six months, limited to a maximum of eight results.

Next we create a template for our custom panel. In dashboard-custom/templates/ we create a RecentlyEditedPropertiesPanel.ss template with the following code:

<div class="dashboard-panel">
    <h3><a href="{$AdminURL}/properties/">Recently edited properties</a></h3>
    <% if $Results %>
    <table class="table">
        <thead>
            <tr>
                <th>Title</th>
                <th>Edited</th>
            </tr>
        </thead>
        <tbody>
            <% loop $Results %>
            <tr>
                <td class="link">
                    <a href="{$AdminURL}/properties/Property/EditForm/field/Property/item/{$ID}/edit">
                        $Title
                        <span class="note">$Address</span>
                    </a>
                </td>
                <td class="link date">
                    <a href="{$AdminURL}/properties/Property/EditForm/field/Property/item/{$ID}/edit">$LastEdited.Nice</a>
                </td>
            </tr>
            <% end_loop %>
        </tbody>
    </table>
    <% else %>
    <p>No properties edited in the last six months.</p>
    <% end_if %>
</div>

We then call ?flush=all in the browser URL to have the new templates and class picked up by Silverstripe.

We can now see we have a recently edited properties panel on our dashboard:
