I have a view of photo nodes uploaded by users and want to group them by post date and user. That part is pretty straightforward once you patch views. Just set sort by "post date" with "day" granularity and add a username field to group by user and day.
I use "count distinct" for nid to show the number of photos by user. I even used "format plural", "no results behavior" and "rewrite output" to only show a link to more photos if there are more than 1 photos per user. So far so good ...
The challenge I'm having is when I try to show a photo and title. When I add the "title" field with "group results" it's now showing each photo instead of grouping. If I use "max" or "min" it will only show 1 photo per user but now the photo won't match the title.
So, how can I show a photo and matching title for photos grouped by day and user? At this point it doesn't matter much if the photo is the oldest or newest for that user and day.
