Dataobject preview
Shows a preview of your dataobjects like the one you get for pages. Works for GridField and ModelAdmin. Works currently only for Versioned DataObjects.
Pending fix: If you switch to "Edit mode" you will not be able to show the preview again since the button gets removed. Will fix it soon.
For the preview to work you need to implement the CMSPreviewable interface on your DataObject and declare the methods Link, CMSEditLink and PreviewLink($action = null).
PreviewLink is the only link we are interested for the preview to work. The DataObjectPreviewController will listen for this links to render your MyDataObject with the MyDataObject.ss template in your theme/templates/* folder.
Example
<?php
class MyDataObject extends DataObject implements CMSPreviewable
{
...
private static $extensions = array(
'Versioned("Stage","Live")'
);
public function PreviewLink($action = null){
return Controller::join_links(Director::baseURL(), 'cms-preview', 'show', $this->ClassName, $this->ID);
}
public function Link() {
...
}
public function CMSEditLink(){
...
}
}
Requirements
