ModelAdmin $summary_fields image width
4 April 2009 at 1:46pm
I am setting up a data management framework using ModelAdmin in 2.3.1.
I would like to display a small image in the summary fields for data objects so users have a quick reference to a piece of artwork to select. Is there a way to use SetWidth() in the $summary_fields for the CMS?
Thanks all, Y

$summary_fields can refer to a method of your dataobject, for example 'ImageForSummaryField' where this method returns the resized image.

Thanks very much for this. Would you mind providing example code to illustrate?

Hey,
seems like this post contains the answer:
http://www.silverstripe.org/general-questions/show/257794
I'm pretty new to Silverstripe as well and have not yet given this solution a try, but as far I understand, you should add a static column "Thumbnail" (next question: which type?) and then add a public function getThumbnail() which than returns the image.
Please post whether this worked.Greets,
Henning

eg (untested):
static $db = array(
'Name' => 'Varchar',
);static $has_one = array(
'Image' => 'Image'
);static $summary_fields = array(
'Name',
'SmallImageThumbnail'
);function SmallImageThumbail() {
return $this->Image()->SetHeight(40);

I tried above example, however i get the following error message.
[User Error] Uncaught Exception: Unable to traverse to related object field [SmallImageThumbnail] on [Ticker]
No matter what I try, i can't seem to get it to work.
I tried naming the function getSmallImageThumbnail, same error.
I tried using TickerImage.CMSThumbnail, same error only with TickerImage.CMSThumbnail instead of SmallImageThumbnail.<?php
class Ticker extends DataObject {
static $db = array(
'LinkType' => 'Enum(\'Internal,File,External\',\'Internal\')',
'LinkTarget' => 'Enum(\'_self,_blank\', \'_blank\')',
'ExternalURL' => 'Varchar(255)'
);static $has_one = array(
'TickerImage' => 'Image',
'TickerFile' => 'File',
'LinkTo' => 'SiteTree'
);static $summary_fields = array(
'SmallImageThumbnail',
'LinkType'
);public function SmallImageThumbnail() {
return $this->TickerImage()->setHeight(50);
}
}
?> -

I wanted to do something very similar a few months ago and found this 'tutorial' very useful:
