Displaying position in admin panel summary fields

Backend
1

I’m trying to figure out how to display the position of my data objects in the summary fields of a GridField in the admin panel. Here’s what I’ve got so far:

private static $summary_fields = [
    'Number' => 'ID',
    'Description' => 'Details',
];

The problem is that I can only access the $Position variable in my SilverStripe templates, but not in the summary fields. Is there a way to show this position information in the GridField summary? I’ve looked through the docs but couldn’t find a clear answer. Any help or suggestions would be really appreciated!

hey there! i had a similar issue. try adding a custom method to ur class like getDisplayPosition() that returns the position. then in summary_fields, use ‘DisplayPosition’ => ‘Position’. it should work! let me know if u need more help

I encountered a similar challenge in one of my projects. A solution that worked for me was implementing a custom getter method in your DataObject class. Here’s an approach you could try:

Define a method like ‘getPositionForAdmin()’ in your DataObject:

public function getPositionForAdmin()
{
    return $this->Position;
}

Then, update your summary_fields:

private static $summary_fields = [
    'Number' => 'ID',
    'Description' => 'Details',
    'PositionForAdmin' => 'Position'
];

This method allows you to manipulate the position data before displaying it in the GridField summary. You can also add logic to format or modify the position value as needed for the admin interface.

oooh, interesting question! have u tried using a custom getter method for the position? something like getGridFieldPosition()? that might work in summary fields. curious to hear what others think… anyone else faced this challenge? maybe there’s a cool workaround i’m not thinking of?
