In the object_list view, you are given an "object_list" parameter, which
is a list of all the objects for that page. To display them, you will be
doing something like
{% for folder in object_list %}
to iterate over that list. Inside that loop, you should then be able to
do
{% for media in folder.media_set.all %}
and so on.

QuerySets are lazy. Since pagination only wants, say, 10 items, it will
end up running "queryset[:10]" and only when the results are needed will
the query be turned into SQL and run. In this case, that will convert it
into a query involving a LIMIT clause, so you don't end up selecting
every single result; just the ones you need.
Am I making any of this clearer? Or just confusing things further? It's
always a bit difficult to know how much detail to put into these
postings, so let me know if I've put too little in this case.
