Getting proper data from Nested DOM
20 August 2010 at 4:18pm
I'm having issues getting the correct data with my Nested DOM. All works except that, so far, I've attached 3 photos to the first room, and it's returning those 3 photos for every Room. I figured that I needed a filter by ID of some sort for the GetRoomPhotos(), but nothing I tried worked.
My RoomsPage lists multiple Rooms (DOM). Each Room has it's own RoomPhoto gallery (Image DOM).
class RoomsPage_Controller extends Page_Controller {
function GetRooms() {
return DataObject::get('Room');
}
function GetRoomPhotos() {
return DataObject::get('RoomPhoto');
}
}In the Template (RoomsPage.ss)
<% control GetRooms %>
...
<% control Top.GetRoomPhotos %>...<% end_control %>
<% end_control %>Here's the full source from the 3 PHP pages if it helps... http://pastie.textmate.org/private/a8scxavuf4v8puuc5wfs5w
Thank you

Look at your two functions. They both return the world of all Rooms or Photos, without regard to the containing object. Get rid of both of those functions.
RoomsPage.ss.
<% control Rooms %>
$RoomName
<% control RoomPhotos %>
$Attachment
<% end_control %>
<% end_control %> -

Hey Uncle C,
Thanks for your help. I tried ditching the functions and changing the template but it wasn't showing any of the photos, the room info was displaying properly.
I then changed 2 things,
- Room.php: my nested ImageDataObjectManager to FileDataObjectManager
- RoomPhoto.php: Attachment => Image to Attachment => FileAnd it started working. Trying to get it to break again, I then restored my files to the earlier versions but it still works. So I'm not sure what was going on.
