Hi there,

i try to accomplish following scenario:

for a photography website i need a gallery-overview page which pulls each newest/first document from its subcontainers/folders without having several Ditto-calls:

GalleryOverview (ID10)
Portraits
- Portrait 01
- Portrait 02
- ...
Landscape
- Landscape 01
- Landscape 02
- ...
Black & White
- Black & White 01
- Black & White 02
- ...

does anyone know how to do this?

and would it be possible to setup ditto, to automatically include a new category (pulling its newest/first document) & without having the client to add the ID of the new category-folder to the Ditto-call (maybe something like &parents=`10` &depth=`3` &hideFolders=`1`?)

thanks, j

This cannot be done with a single Ditto call, but through the appropriate manipulation of the recursion it is possible to solve this task with a single clause that will meet all your requirements.

I assume that the mentioned documents ("GalleryOverview", "Portraits", "Portrait 01", ...) are all containers. Photos are located under "Portrait 01", "Landscape 01", "Black & White 01", etc. Right? If so, then the task might be solved with something of this kind:

[[Ditto? &parents=`10` &depth=`2` &display=`all` &filter=`isfolder,1,1` &tpl=`newest-photo`]]

The above will catch all containers under "GalleryOverview" for two levels in depth. Now the most important part, content of the "newest-photo" chunk:

[[Ditto? &parents=`[+id+]` &depth=`1` &display=`1` &filter=`isfolder,0,1` &tpl=`PhotoDoc` &sortBy=`createdon` &sortDir=`DESC`]]

This chunk pulls newest (latest) photo doc for the each container caught on the first level of Ditto's call. I have tested this idea and it is working.
