Comment (by Amit Upadhyay <[EMAIL PROTECTED]>):
Replying to [comment:8 [EMAIL PROTECTED]:
> Another approach to solving this issue: instead of storing references to
the next/previous pages (the contents of which change as new objects are
added), there could be an option to store references to the next/previous
OBJECTS based on what's already on the page. So say you had 372 objects,
and you were looking at the first ten (so objects 1-10). Instead of a
"previous page" link with a "?page=2" string attached, you'd have a
"previous 10" link with a "?object=11" attached, a signal to start the
next page with object 11.
object==1 is the oldest item or the newest? This will decide the queryset
ordering. This will also decide if caching stays or gets invalidated when
new items are added. This will also decide if the page is bookmark-able or
not.
You are confusing the discussion of "should pagination be forward of
backward?" with "should we paginated by using page no. or object index?".
They are mutually exclusive discussions, and both will have to be
answered. I just assumed the second question is answered, and page number
was found to be "better" than object.
